Pipe stress analysis blog project manager graphic (1)

If you manage a process plant, power facility, or oil and gas operation, you know that piping systems are at the center of your entire operation. But how often do you think about the hidden forces: the intense pressures, temperature shifts, and vibrations that are constantly pushing your pipes to their breaking point?

Ignoring these forces isn’t just a risk; it’s a guaranteed path to costly downtime, failures, and safety hazards. This is where pipe stress analysis comes in: it’s the essential engineering practice that ensures your piping system not only works but lasts.

What Exactly is Pipe Stress Analysis?

Caesar2

CAESAR II PSA

Pipe stress analysis is a systematic, mathematical study used to evaluate the stresses and displacements in a piping system. Think of it as a comprehensive health check-up for your pipes.

An engineer uses specialized software to build a virtual model of your entire system. They then subject this model to all the real-world conditions it will face:

  1. Pressure: The internal force from the fluid or gas being transported.
  2. Temperature: The thermal expansion and contraction that occur as the fluid’s temperature changes (often the single biggest source of stress).
  3. Weight: The dead weight of the pipe, fluid, and insulation.
  4. External Loads: Forces from wind, seismic activity (earthquakes), or external equipment (like pumps or valves).

The goal is to verify that the stress imposed on the pipe wall, fittings, and supports remains within the limits defined by industry codes, such as ASME B31.3 for process piping.

Why Is This Analysis Critical for Your Operation?

Skipping or shortchanging pipe stress analysis is a classic example of being penny-wise and pound-foolish. The costs of a failure far outweigh the cost of analysis.

1. Prevent Catastrophic Failure and Leaks

The most immediate benefit is safety. Excessive stress can lead to fatigue cracking, flange leaks, or even a sudden rupture. Analysis ensures that your system can handle every operational scenario without a catastrophic failure that endangers personnel and the environment.

2. Protect Expensive Equipment

Piping doesn’t exist in a vacuum; it connects to critical, often multi-million-dollar equipment such as pumps, turbines, and heat exchangers. If a pipe expands excessively and pulls on a connected nozzle, it can cause severe damage or destruction to that equipment, resulting in substantial replacement costs and prolonged downtime.

3. Ensure Reliability and Uptime

A properly analyzed and supported system experiences less vibration, less wear on supports, and fewer flange leaks. This directly translates into higher operational reliability, minimizing unexpected shutdowns —the biggest drain on a plant’s profitability.

4. Improve Support Selection

This is where analysis meets reality. Once the stress engineer knows where the forces are greatest, they can correctly design and specify the right supporting elements. Are standard clamps enough, or do you need specialized solutions such as pipe shoes, slides, or anchors to manage movement and transfer loads safely to the structure?

Pipe Stress Analysis Software

Autopipe psa

AutoPIPE PSA

Performing a thorough pipe stress analysis is a task too complex and iterative to be done manually. Specialized pipe stress analysis (PSA) software is essential for creating detailed virtual models, applying various load cases, and performing the millions of calculations required to comply with industry codes.

These sophisticated programs allow engineers to:

  • Rapidly model complex pipe routing, components (valves, fittings), and support structures.
  • Accurately simulate real-world conditions like thermal expansion, seismic events, wind load, and transient conditions (e.g., water hammer).
  • Automatically check results against stringent design codes (e.g., ASME B31.3, B31.1) to confirm compliance.

A few key players dominate the market, each offering powerful tools with slightly different specialties and features. The most recognized and widely used software packages globally include:

  • CAESAR II (Hexagon): Arguably the industry standard, known for its extensive code compliance checking and user-friendly interface.
  • AutoPIPE (Bentley Systems): Highly capable, often praised for its integration with CAD and structural analysis programs.
  • CAEPIPE (SST Systems): A well-established tool favored for its speed and intuitive graphical user interface (GUI).

Selecting the right software is crucial, as its accuracy and features directly impact the reliability of your final design. The results of this virtual analysis guide real-world decisions about where and how to place the critical pipe supports.

The Support Solution is Key

Stress analysis identifies the problem, but pipe supports are the engineered solution. If a study shows excessive movement or load on a critical elbow, the correct support, chosen for its material, design, and load capacity, is essential to resolve the issue.

At Pipe Shields, we specialize in high-quality, engineered supports that implement the findings of your stress analysis. We turn theoretical safety into physical reliability. By using the right shields, slides, and clamps, you ensure that the structure in the field safely manages the stresses calculated in the model.

Variable Spring Sizing

Piping systems are used to transport gases, liquids and suspended solids between units of a plant. The temperatures of the contents and the pipe when the plant is in operation are often quite different from the ambient temperature of the surroundings. The heat transferred during changes in temperature causes metal pipes to expand and contract. Piping designers must provide for movement due to temperature changes and forces caused by pumps, gravity, and other elements of the piping system.

Proven engineering practices are included in various codes for piping services developed by professional societies such as the American Society of Mechanical Engineers. Most companies use these codes to develop specific standards for their products. The Manufacturers’ Standardization Society has developed standards for pipe supports. Designs that satisfy codes are important to satisfy laws and to obtain financing and insurance for projects. Table 1 provides a list of some important standards.

Variable Spring Supports Ready for Shipment

 

Variable springs are one of the most important devices available to help support pipes. They are used to balance the concentrated gravitational load of vertical sections of pipe while allowing for thermal movement. Control of the direction and amount of movement of various sections of pipe is a major function of piping design. Computer models are used during design to predict the forces and movement at the point where a spring support is attached to the pipe. This is the information required to select the least expensive variable spring to use.

Variable springs are relatively inexpensive and very reliable. When replacement is necessary, the engineer needs to determine if the original size is still appropriate or if the system has changed and different forces and movement must be considered.

Table 1

Pipe support manufacturers product catalogs which describe the items they routinely supply. The engineered spring support section of our catalog contains detailed information on variable springs. The load and travel tables contain the information required to size variable springs. An abbreviated version of this table is given in Figure 6.

 

Physics of Spring Coils

Variable spring supports are attached to piping systems so the coil is in a vertical position as shown in Figure 1. Forces which compress the coil act in the same direction as the force of gravity. Movement due to temperature changes may be either up or down. Movement is a vector which has both direction (up or down) and magnitude. Travel is a scaler which describes the length of movement or compression of the spring coil.

A spring can only be compressed so much before the individual coils come together and it “goes solid”. The usual method used to provide for larger travel is to provide a longer coil or stack standard coils together as shown in Figure 2.

Force of GravitySpring Sizing Scale

Newton’s Third Law of Motion states that every force is accompanied by an equal and opposite force. A spring coil resists the force which compresses it. The more the coil is compressed, the greater resistance it has to further compression. This is why pipe supports which apply forces directly to the spring coil are called variables.

The magnitude of the force required to compress a spring coil depends on the size of the wire used to form the coil and on the diameter of the coil. A “stronger” coil can be produced by using a larger wire or by winding the wire “tighter”. The two industry standards are the PTP-1 (short spring) and the PTP-2 standard spring. Twenty-three different wire sizes from .23 inches to 2.5 inches are used to increase the size of the force required to compress the coil. At PT&P, we use 00, 10,…,200, 210, 220 to designate the wire size (resistance to force) of the coil as shown in the top of Figure 6.

Figure 3 shows a graph of pounds-force required to compress a PTP-2, size 90 coil as a function of the amount of compression. The graph is a straight line through the origin with a slope of 200 pounds-force per inch of compression. The slope of this line is the spring rate of this variable support. We compress the coil three inches during assembly (using 600 pound-force). The variable produced can be further compressed an additional 3.5 inches (range of deflection) by applying 1300 pounds-force. Each additional 200 pounds-force will compress the coil one inch.

 

Figure 3

Manufacturers recommend that only 80% of the range of deflection (called the operating range) be used for variables. The PT&P load and travel table uses red lines to enclose the loads in the operating range. Figure 3 marks both the minimum and maximum loads (700 and 1200 pounds-foce) for the operating range with red lines. The load at the center of the operating range (950 pounds-force) is marked with a blue line. The total compression of the coil at 700 pounds-force is 3.5 inches and the compression at 1200 pounds-force is 6.0 inches so the operating range is 2.5 inches.

Figure 6. shows how to obtain these values from the load and travel table of our catalog.
Figure 4

Selecting the Proper Size for a Variable

The coil size (force required for compression) should be chosen to balance the expected force on the support when the system is operating. To do this, choose the size (00 to 220) which has its center compressive force (blue line) in Figure 6 as close as possible to the Operating Load (“hot load”). Choose the shortest (least expensive) coil and operating range which will satisfy the expected movement the support will experience during the temperature changes expected going from cold load (non-operating force applied) to operating load.

Figure 5 illustrates the relation between the three quantities, operating load, cold load and movement. The direction of movement is defined by the change of load (force on the support) when the system changes from cold to operating. If the operating load is greater, the increase in the force will further compress the coil so the direction of the movement is down. If the operating load is smaller, the decrease in the force on the support will allow the coil to expand so the movement is up.

 

Figure 5

Figure 6

Variability Constraint

The change in the force on the support when changing from cold to operating is equal to the spring rate multiplied by the Travel (magnitude of the movement). Good practice as specified in MSS code requires that this change experienced by the support should be no more than 25% of the operating load, thus the inequality in Equation (a) must always be satisfied. Note that the spring rate is a function of both the coil size (Z) and the coil length (X). Coil size Z is chosen to match the operating load, so X is chosen as small as possible to satisfy Equation (a). The possible values of X are 1,2,4,6, and 8 which correspond to PTP-X and define the operating range of the support.

U-Type Constants Designed with Slide Plates for a Polypropylene Plant in Texas

test service nolan

147164a1

Constants use a spring coil (or series of coils) to accommodate pipe movement from the initial (installed) condition to the final (operating) condition of the piping system. For all constant spring supports, there is no difference in load, and the supported load will remain uniform throughout the deflection cycle.

PT&P designed and fabricated a U-Type constant spring support , with PTFE and a 25% glass-filled side plate for a Polypropylene Plant in Texas. The constant is fabricated from carbon steel and hot-dipped galvanized for extra protection against corrosion. The vertical movement is 1.5″ total upward travel and is capable of supporting a load of 10,350 lbs. throughout its range of movement. The constant underwent standard load testing prior to shipment.

Along with chemical plants, constant spring supports are utilized in refineries, power plants, and heat recovery steam generators (HRSG). The design of the constant spring support replaced a system of pipe support called a “counterweight” design still used in some facilities today. The counter-weight system utilized pipe clamps or lugs (attached or welded to the pipe), cables, pulleys, and a set of weights. Just like the old-fashioned brass weighing scales, weights were added to one end of the pulley system until an equilibrium was reached. The counterweight design needed a large amount of space with which to operate. Constant spring hangers replaced this system because they require much less space in order to function (similar to some designs we stand on to weigh ourselves). No matter the application, our team of experienced engineers and designers can help to resolve your pipe support needs.

Cold Shoes and Hot Shoes Designed for an Ammonia Project

Insulated Pipe Supports Designed for Cryogenic and High Temperature Pipe Systems for an Ammonia Project

Insulated pipe supports are designed to prevent direct heat transfer between pipes and their supports. Thus, they prevent heat loss due to conduction at each support. Whether a cold or hot temperature pipeline, the transfer from cold to hot or hot to cold is prevented.  They serve the following purposes: Carry the load and allow necessary movement (when used with slide plates) at each point of support, provide insulation in the support area where the regular pipe insulation is not sufficient to support the load and minimize installation costs by reducing the time required to install the support. The supports are not welded to the pipe, and each unit is shipped completely assembled (except for the riser supports and anchor supports, both of which require some welding).  In HVAC and plumbing applications, insulated supports also help prevent condensation and corrosion under insulation (CUI) by maintaining the vapor barrier at the support point. Their use contributes to better energy performance, reduced maintenance, and compliance with MEP design standards focused on energy efficiency and moisture control in building systems.

For this project, we custom-designed 98 insulated pipe supports for an ammonia project at a chemical plant in Louisiana. The supports were designed for both cryogenic and high-temperature pipe systems, with an 8″ to 22″ baseplate width and a 10″ to 28″ saddle length. They were designed for pipe diameters of 6″-24″ and are composed of polyurethane foam for cryogenic and high-density calcium silicate insulation for high temperatures. Standard Q.C. and dimensional tests were performed prior to shipment.  

This project was a combination of upgrading a current anhydrous ammonia plant and adding new capacity to the facility.  We worked with the EPC, on-site contractors, and operators to ensure specifications and delivery deadlines were met over a three-year period during project construction.  In addition to the insulated supports discussed here, we designed, manufactured, and shipped bellmouth reducers, metallic expansion joints, pipe shoe guides and anchors, pipe hanger hardware, slide plates, snubbers, sway braces, struts, and variable spring supports.

Beyond ammonia and chemical processing facilities, insulated pipe supports are widely used across other industries where thermal control and system integrity are essential. These include petrochemical plants, LNG and cryogenic gas facilities, power generation plants, and district energy systems for heating and cooling networks. They are also integral to MEP infrastructure in data centers, pharmaceutical manufacturing, and food processing plants, where preventing condensation and maintaining precise temperature control are critical. In each of these applications, insulated supports help maintain energy efficiency, protect against corrosion under insulation, and ensure long-term reliability of piping systems operating under extreme temperature conditions.

Unlocking Pipeline Efficiency: The Ultimate Guide to Pig Launchers

test service nolan

Us bellows pig launcher

Your pipeline is the circulatory system of your operation, and just like a human body, it requires routine maintenance to function at its peak. 

In chemical and petrochemical industries, pigging systems are used to separate different products within a pipeline to prevent contamination, as well as for cleaning and inspection. In water and wastewater treatment, they help remove sediment, biofilms, and scale from municipal mains to improve water quality and flow efficiency. In the food and beverage sector, pigging is employed to reclaim valuable products and prevent cross-contamination when transporting different batches of liquids such as chocolate, dairy, or juices. Similarly, in pharmaceuticals and cosmetics, pigging is applied in sanitary processes to clean and inspect pipelines, ensuring product purity and compliance with strict hygiene standards.

Pigging: the act of using a device called a “pig” to clean, inspect, or maintain a pipeline, is the most effective way to achieve optimal performance from your piping operation. And at the center of any successful pigging program is the pig launcher.

A pig launcher is a specialized piece of equipment that safely introduces a pipeline pig into a pressurized line. It’s a critical component that delivers efficient and safe pigging operations. 

Choosing the right one is important. This guide will help you understand the benefits and options available, enabling you to make an informed choice that will aid in maintaining a debris-free piping operation.

Equipment

The physical infrastructure is essential for any pigging operation. This equipment, including pig launchers and receivers, enables the safe and efficient introduction and removal of pigs from the pipeline.

  • Pig Launcher: An oversized section of pipe where a pig is loaded and then launched into the main pipeline. It’s equipped with a quick-opening closure for easy access and various valves to control pressure and fluid flow.
  • Pig Receiver: Located at the end of a pigging run, this is a similar oversized section of pipe designed to catch the pig and any debris it pushes. It also features a quick-opening closure for retrieving pigs and debris.
  • Kicker and Bypass Lines: The kicker line is a smaller pipe that directs a portion of the product flow into the launcher to propel the pig. Bypass lines are used in receivers to allow continuous product flow while the pigging process is underway.

Why Pig Launchers Are Important for Your Piping Operation

Investing in a quality pig launcher isn’t just about maintenance; it’s about safeguarding your assets and maximizing your return. The benefits extend far beyond a clean pipe:

  • Boosted Productivity and Flow: Debris, wax, and scale buildup inside pipelines can restrict flow, increase friction, and reduce overall throughput. Regular pigging removes these blockages, improving flow rates and boosting operational efficiency.
  • Reduced Operational Costs: By recovering valuable products, minimizing waste, and decreasing the need for extended shutdowns for manual cleaning, pigging systems can lead to significant cost savings.
  • Increased Safety: Modern pig launchers are designed with safety features, such as quick-opening closures and pressure relief devices, to protect personnel and equipment during operations, thereby mitigating risks associated with high-pressure systems.
  • Product Batching and Separation: For companies that transport different products through the same pipeline, pigging allows for the effective separation of batches, preventing cross-contamination and ensuring product purity.

For a deeper dive into how custom solutions can address specific challenges, read our companion piece: Custom-Designed Pig Launcher.

Your Options: Choosing the Right Pig Launcher

Pig launchers are not one-size-fits-all. They are highly customized based on your specific application, pipeline dimensions, and operational needs. Here are the key factors you need to consider:

Sizing and Pressure

The most important considerations are the size of your pipeline and the operating pressure. The launcher’s major barrel must be large enough to hold the pig, while the minor barrel must match the diameter of the pipeline. Our capacity for design pressure range is up to  4000 PSIG (pounds per square inch gauge) for pig launchers and receivers:

Material Selection

The material of the launcher is critical for lifespan, application, and media integrity . Most are fabricated from carbon steel, but for corrosive or sanitary/food grade applications (e.g., food and beverage/pharma), materials like stainless steel are often required to prevent contamination and withstand harsh environments.

Level of Automation

Pig launchers come with various levels of automation. From simple, manually operated systems with flag indicators to fully automated, remotely controlled units, the choice depends on your budget and the frequency of pigging operations. Automated systems reduce operator involvement, increase safety, and enable more frequent and aggressive pigging programs.

Things We Need to Know, Before We Quote a Pig Launcher or Receiver 

  • What will the launcher be used for, liquid or gas? This will determine the design code.
  • What will be the pressure and temperature of the fluids in the operating system?
  • Will you need supports (legs) to be included?
  • What type of finish will you select? The standard finish is our shop primer.
  • Do you have any special requirements? Anything added to a launcher or receiver can increase both complexity and cost.
  • What is the location of closure, where the pig will be loaded? As pressure requirements increase, closure options become more restrictive.

Specialized Features

To optimize your system, consider these options:

  • Quick-Opening Closures: These are essential for safe and rapid access to the launcher barrel, allowing for the insertion or retrieval of the pig.
  • Instrumentation Ports: These allow for pressure monitoring, while vents and drains are crucial for depressurization and cleaning.
  • Bypass Lines: A bypass allows product flow to continue while the launcher is offline for maintenance.

Multiple-Pig Systems: For complex operations, launchers can be designed to hold and launch multiple pigs in sequence, which is ideal for multi-stage cleaning or intelligent inspection.

At Sweco Fab, a Piping Technology & Products company, we offer the following capabilities for pig launchers and receivers:

Built for Real-World Vertical Support: Custom Riser Clamp Assemblies That Hold the Line

test service nolan

Pipe Clamp Assemblies Custom Designed for a Partial Oxidation Unit in a Synthetic Gas Plant

When vertical piping in a high-pressure system starts to shift, everything downstream is at risk. Hanger misalignment, accessory failure, and field delays would be the least of your worries when vertical pipe systems experience axial displacement. 

That’s where Piping Technology & Products’ custom riser clamp assemblies deliver assurance engineers can count on. With the proper design specifications, PTP can manufacture precision riser clamps that ensure secure and reliable product delivery.

Purpose-Built for Vertical Load Control

Riser clamp assemblies are specifically engineered for vertical pipe systems where axial movement must be restricted. It is not a one-size-fits-all product. Each assembly is fabricated to fit exact pipe diameter, temperature, and load specifications, most commonly for critical process lines in synthetic gas, petrochemical, or tall vertical rack applications.

At its core, the assembly relies on a heavy-duty steel clamp secured around the pipe, working in tandem with thrust plates to manage axial loads. 

For high-heat applications, manufacturers utilize A387 alloy steel (rated for service temperatures of 750°F to 1,000°F) and a high-temperature coating that won’t degrade or flake under scorching conditions.

Once installed, the clamp limits movement in the downward direction, ensuring the pipe doesn’t slip under load or due to temperature expansion. Engineers often pair the clamp with spring hangers or sway struts for a complete load path solution.

Real-World Application: Synthetic Gas Plant Retrofit

At the request of a synthetic gas facility, PTP engineered a custom riser clamp assembly for their high-temperature vertical piping. We used Alloy A387, a heat-resistant steel specifically selected for service temperatures reaching up to 1,000°F, to fabricate this assembly. 

To ensure performance under thermal cycling, we coated the clamp with a high-temperature industrial-grade coating designed to withstand prolonged exposure without degradation. By preventing vertical slippage during system startup, the clamp maintained alignment integrity and eliminated the risk of early rework or other types of damage to the pipeline.

Common Use Cases for Riser Clamp Assemblies

Riser pipe clamp assemblies serve a critical role in applications where vertical piping must be securely supported and restrained. 

Engineers commonly use them on vertical risers in fired heater loops, where high temperatures and axial loads demand reliable restraint. They also support tall structural pipe racks in petrochemical plants, ensuring alignment across multi-level piping systems. 

In high-rise and offshore environments, riser clamps provide secure anchoring for firewater systems subject to seismic or dynamic loading. Additionally, LNG facilities rely on them for vertical steam lines that require thermal movement control and long-term integrity.

Key Benefits for Field Execution

PT&P’s custom riser clamp assemblies provide clear advantages for vertical piping systems. 

They prevent pipe slippage by firmly securing the line in place, ensuring axial stability under load. 

Each assembly is custom-sized to match the exact pipe outer diameter, specified load, and temperature range, eliminating fit-up issues during installation. 

PT&P designs these supports to handle pipe sizes up to 48 inches and fabricates them with high-temperature materials and coatings that perform reliably in scorching environments. 

Engineers apply Finite Element Analysis (FEA) to optimize steel thickness, reduce excess material, and validate structural integrity. 

By managing design, fabrication, and delivery in-house, PT&P minimizes handoffs and reduces the risk of delays or errors throughout the supply chain.

Why Engineers Choose Riser Clamp Assemblies

Engineers value this clamp for its precision and structural integrity. Load ratings are validated through FEA, ensuring that the clamp can stand against almost any surprise event. For jobs with elevated temperatures or non-standard loads, our custom approach removes guesswork from spec compliance.

Why Project Managers Chose Riser Clamp Assemblies

What sets these clamps apart is how they minimize scope creep. 

When clamp assemblies are properly designed from the start, there’s no field modification, no install surprises, and fewer RFIs. The result: less rework, better schedule control, and a clear value add during procurement planning.

Trunnion Base ELL (Elbow) Pipe Supports for Cryogenic Piping: Proven Thermal Isolation and Custom Fit

test service nolan

Trunnion Base ELL Supports for a Cryogenic Line
Trunnion Base ELL Supports for a Cryogenic Line

What is a Trunnion Pipe Support?

A trunnion pipe support is a structural component used to support a piping system and is connected directly to the process line. It functions as a secondary pipe element, helping hold the main line in position for stability.  ASME standards guide their application and analysis to ensure safety and reliability, particularly in high-energy piping and under various operating conditions. 

In standard applications, trunnions are used to:

  • Support sections of pipe vulnerable to weight or stress
  • Help manage pressure at directional changes like elbows
  • Provides added stability and structural strength by helping reinforce the system at critical load points
  • Prevent displacement under heavy loads or external forces

In cryogenic systems, however, added challenges emerge. Maintaining thermal insulation at support points is critical. Without it, heat transfer through the support could lead to the evaporation of liquids into gases, cause condensation, and/or result in ice buildup. Over time, this can damage the pipe or disrupt flow.

Custom Trunnion Base ELL Pipe Supports for Cryogenic LNG Applications

Trunnions Designed with Insulation for an LNG Facility
Trunnions Designed with Insulation for an LNG Facility

At an LNG gasification facility, our customer required pipe supports that could prevent the transfer of heat and provide trunnion-like stability and strength. Piping Technology & Products collaborated closely with the client to design a customized solution that met both mechanical and thermal performance requirements.

The result was a trunnion base ELL support with a layered construction: an A36 carbon steel base, an integrated insulation block, and a stainless steel pipe saddle. This configuration prevented heat transfer between the pipe and the support.

By incorporating an insulation block into this design, we prevented heat transfer from the trunnion pipe support to the process line, which is a feature that a standard trunnion does not offer. The trunnion keeps the cold pipe separated from warmer support steel, suppressing frost build-up at the base and pipe rack. The pre-insulated support design maintained a steady temperature for the LNG from Point A to Point B, preventing it from warming up and converting from a liquid into a gas.

What Is a Trunnion Base ELL Support and How Does It Work? 

A trunnion base ELL support for LNG applications is a specialized insulated pipe support designed for cold-service and cryogenic process lines. It supports the main pipe while creating a thermal break between the pipe and the support base.

Unlike standard trunnions, which are not designed to address thermal integrity, this design minimizes thermal bridging. 

It typically uses:

  • A carbon steel base for structural strength
  • A block insulation layer to isolate temperature
  • A stainless steel pipe saddle that connects to the process pipe

Where Trunnion Base ELL Supports Are Used

Trunnion base ELL supports are specifically designed for cold-service environments where thermal performance is critical. 

They are commonly used in LNG liquefaction and gasification facilities, where maintaining sub-zero temperatures is essential to system operations and safety. These supports also play a key role in ethylene and ammonia plants, which use chilled piping to move process materials while minimizing energy loss. 

In all cases, the design enables operators to move product from one stage to the next without experiencing temperature changes, condensation, or structural complications caused by frost buildup.

Key Field Benefits

  • Thermal isolation is built in; it prevents cold pipe surfaces from transferring extreme temperatures to structural steel, helping maintain safe operating loads without added field insulation.
  • Reduces condensation, prevents ice formation, and pipe damage
  • Custom-fit to specification for pipe sizes ranging from 2 in. to 60 in., fitting cleanly into the line
  • Supports heavy vertical loads while preserving pipe wall integrity
  • Material matched to the parent pipe  to maintain mechanical and chemical compatibility
  • Delivered fast, often within weeks, even for custom builds
  • Provides rigid support in low-movement areas, preventing pipe sag or collapse in static runs or where line displacement is minimal.
  • Helps reduce stress at elbows and vertical transitions, reinforcing piping in high-pressure or structurally sensitive locations.

Why Engineers Choose Trunnion Base ELL Supports

Engineers specify trunnion base ELL supports when thermal isolation is non-negotiable. These supports are sized according to the process pipe’s outside diameter and insulation thickness, ensuring a proper interface without modifying the pipe’s thermal envelope. 

The materials used, including carbon steel (for areas not in direct contact with the process line), high-performance insulation, and stainless steel, are known to perform reliably in environments that reach as low as -300°F.

Why Project Managers Trust It

Project managers rely on trunnion base ELL supports to avoid the common pitfalls that delay cold-service projects. Because the insulation is integrated into the support design, there’s no need to coordinate separate insulation crews or handle last-minute RFIs about support height or fit-up. 

Eliminating this extra field work speeds up installation, lowers labor coordination complexity, and reduces the risk of frost-related damage during startup. By arriving job-ready and material-matched, these supports enable faster handoff to commissioning teams and help keep the schedule on track.

Pipe Support Walkdowns

test service nolan

Img 2870

 

Even the best-designed piping systems can deteriorate over time or encounter challenges due to improper installation or maintenance cycles that need updating.  

A pipe support that’s even half an inch too low can throw off alignment, especially for sensitive rotating equipment. Improper alignment of pipe shoes set at the wrong height, spring cans locked in place due to shipping, or non-functioning pipe supports can go unnoticed, and sometimes not until a costly unexpected shutdown occurs. 

A pipe support walkdown, performed by subject matter experts (SMEs), helps identify these issues before they become costly.

Solution: What is a Pipe Support Walkdown and How Does it Help?

A pipe support walkdown is a field-based verification process for any system using pipe supports or rotating equipment. 

A qualified technician or engineer inspects the installed pipe supports to confirm everything matches the design intent and is safe for operation. That means:

  • Verifying metallic expansion joints are properly aligned, anchors are secure, and shipping bars or restraints are removed to allow unrestricted axial or lateral movement during system operation.
  • Checking spring hangers are unlocked and set to the right load.
  • Verifying hold-downs, clamps, and anchors are tightened and positioned correctly.
  • Catching missing or incorrectly installed components before startup.
  • Ensuring fabric expansion joints are installed without twisting or distortion, frames are properly sealed, and flow direction indicators are correctly oriented to prevent leaks or premature wear.

A pipe support walkdown is not paperwork review. It’s boots-on-the-ground risk prevention.

 

Key Safety and Performance Benefits

  • Prevents startup failures by identifying locked supports, improper loading, or misalignment.
  • Protects against stress failures like cracked welds or ruptured anchors
  • Verifies load positions so pipe weight transfers as intended
  • Quickly identifies worn or failing rubber, fabric and metallic expansion joints
  • Confirms movement clearance for thermal expansion
  • Reduces incident risk for maintenance and operations teams

Engineer’s Take: Technical Insurance for the System

Walkdowns provide engineers with a final check on real-world variables, such as actual pipe weights, true centerlines, and friction conditions. They’re essential for validating that thermal movement will be absorbed by the system as designed, not resisted due to incorrect installation. For supports like spring hangers and slide plates, this is the only way to confirm field settings match the spec.

 

Project Manager’s Take: Stop Delays Before They Start

For PMs, plant walk downs are a high-leverage activity. One afternoon walk can prevent weeks of delay from an avoidable error. They reduce RFIs, holdbacks, and rework providing owners with confidence during system turnover. By validating installs, walk-downs keep your project on schedule and helps avoid costly failures and shutdowns.

 

Pipe Supports to Check and Verify During Walkdowns

  • Variable spring hangers
  • Constant supports
  • Rubber, fabric, and metallic expansion joints
  • Sway struts, snubbers, and anchors
  • And more

PTFE Slide Plates: Built for Real-World Movement

test service nolan

Custom Designed PTFE Slide Plate and Pipe Shoe Assemblies

In many situations, fixed equipment must be able to move in axial and/or lateral directions. 

Surfaces where controlled movement is desired are ideal for Piping Technology’s PTFE Slide Plates. Typically, you will find these slide plates underneath pressure vessels or other heavy equipment, such as pumps and compressors, that must be able to move freely along their support surfaces to prevent unplanned outages or operational downtime. 

Without PTFE Slide plates, friction between metal components puts your equipment at risk of misalignment, ruptured lines, or anchor failures, which in turn shortens the lifespan of both piping and equipment.

PTFE (polytetrafluoroethylene) slide plates help prevent these issues by providing a low-friction interface, enabling smooth movement.

What’s at Stake in the Field

Whether it’s a pipe shoe sliding on a beam or a heavy vessel on embedded steel, surface friction can lock systems in place, causing stress and damage. Without the right slide interface, steel-on-steel friction causes wear, cracking, and eventually system failure. 

PTFE slide plates resolve this issue by reducing friction and maintaining structural alignment, which is especially crucial during thermal cycling. As temperatures fluctuate, pipes expand and contract, and the slide plates allow for this pipe movement without stressing supports or causing misalignment.

How PTFE Slide Plates Work

PTFE slide plates are two-part assemblies. PTFE is bonded to a carbon steel bottom plate and is also bonded to the top plate, which makes up the slide plate assembly. Once the bottom assembly is attached to the existing steel and the upper assembly is connected to the bottom of a pipe shoe or trunnion, a low-friction surface is created, allowing for both axial and lateral movement. The PTFE layers are mated from the upper and lower assemblies, allowing movement between the moving component and a fixed support beam or surface.

The result: Easy, controlled movement that reduces load transfer to anchors, minimizes friction, and extends equipment life.

Real-World Example: Natural Gas Pipeline Using PTFE Slide Plates

An international pipeline construction company partnered with us to supply PTFE slide plates for a major gas pipeline project in Africa.

The slide plate assemblies supported pipe shoes mounted on structural steel beams, accommodating both axial and lateral movement while maintaining structural stability.. 

We engineered and delivered twenty guided cradle supports, ranging in size from 8″ to 30″. Each was fabricated from carbon steel and painted for corrosion resistance.  

Thanks to our in-house inventory of PTFE, we accelerated production and avoided costly field delays, delivering exactly what the project needed, right on time.

Where PTFE Slide Plates Are Used

  • LNG terminals
  • Petrochemical plants
  • Refineries
  • Power plants
  • Beneath equipment like pumps and compressors
  • On spring supports 
  • Bridges: Highway bridges, overpasses, railroad bridges
  • Cross-beam and girder slip joints

Key Benefits of PTFE Slide Plates in the Field

  • Produces a low coefficient of friction between a stationary support element and the moving pipe support component
  • Enables controlled pipe movement to prevent overstress during thermal expansion
  • Ideal for low-heat and high-velocity conditions.
  • Minimizes friction between steel components, reducing wear
  • Pairs easily with other supports like pipe shoes and spring cans
  • Operates effectively from –320°F to +500°F, maintaining its low-friction properties across this wide temperature range

Engineer’s Take: Why Choose Our PTFE Slide Plates

PTFE slide plates are a trusted choice for engineers thanks to their high load-handling capacity, consistent low-friction performance, and long-term durability. 

We offer sizes ranging from 4″ x 4″ to 12″ x 12″ (and larger if needed), engineered to support both lateral and axial movement without compromising structural integrity. 

Unlike most suppliers, we stock PTFE in-house, ensuring faster lead times and dependable availability. We can custom-manufacture slide plates to your exact specifications, including custom shapes, thicknesses, and bonding requirements. 

PTFE is easy to install, requires no surface treatment or grouting, and performs reliably in all weather conditions, making it a smart, low-maintenance solution for demanding applications.

Inspection and Upgrading of High Energy Piping Systems

test service nolan

This technical paper, presented at the 1987 Joint Power Generation Conference by engineers from Brown & Root U.S.A., Inc., addresses the critical need for systematic inspection and upgrading of high energy piping systems (HEPS) in power plants. Despite often being considered low-maintenance, these systems are prone to failures due to thermal fatigue, creep, vibration, and corrosion, particularly at welds, hanger points, and fittings.

The study identifies common failure locations, such as main steam lines, hot reheat lines, and boiler piping, and explains that older fossil fuel power plants are especially susceptible. Using historical data and case studies, the authors categorize failure types and associate them with specific plant components and operating conditions.

To mitigate these risks, the paper outlines methods to detect impending failures, including:

  • Stress analysis,
  • Visual and non-destructive inspection techniques (NDE),
  • Monitoring of pipe hangers and supports.

The authors emphasize the importance of systematic evaluation of symptoms (like pipe displacement or equipment overload), root cause diagnosis, and the application of targeted corrective actions, such as support replacement or system modification.

Overall, the paper provides a practical framework for maintaining the reliability and safety of HEPS, advocating for proactive maintenance strategies and the integration of modern diagnostic tools to prevent costly and hazardous failures.

Hydraulic Snubbers Built for Real-World Events

test service nolan

Hydraulic Snubbers Designed for a Geothermal Facility

Designed to control movement during impulse and prevent sudden displacement 

When thermal movement, seismic activity, or pressure surges strike, unrestrained piping systems can suffer catastrophic failures. For project managers and engineers tasked with safeguarding critical infrastructure in unpredictable environments, hydraulic snubbers provide a tested and proven line of defense.

Without them, it could lead to breaks in the piping system, cause misalignment issues, and/or anchor bolt failure. With tight project schedules and in high-risk applications, that’s a scenario no one can afford.

How Hydraulic Snubbers Work

Hydraulic snubbers allow free thermal movement during normal operating conditions. But when a sudden shock load occurs, such as a water hammer, blast, or seismic event, the hydraulic snubber reacts instantly to restrict movement.

By automatically locking up during sudden displacement and staying passive during slow, normal motion, they effectively protect the piping system without interfering with normal operation. This dual-mode performance makes them ideal for high-performance applications requiring both flexibility and protection.

Case in Point: Custom Manufactured Hydraulic Snubbers for a California Geothermal Plant

For a geothermal facility in California, Fronek Anchor/Darling, a division of Piping Technology & Products (PT&P), designed and fabricated high-load hydraulic snubbers tailored for seismic resilience. In this application, our engineers designed two unique snubbers and a three-bolt pipe clamp:

  • Hydraulic snubbers designed for a 50,000 lb. max load, 5” cylinder, 6” stroke, measuring 34 ¾” to 37 ⅝” piston-to-piston.
  • Hydraulic snubbers designed for a 20,000 lb. max load, 2 ½” cylinder, and 6” stroke, measuring 56 15/16” to 59 5/16” piston-to-piston. 
  • Custom three-bolt carbon steel pipe clamps designed to fit the snubbers and accommodate the high loads.

Before shipment, our quality and production teams performed cycle testing on each hydraulic snubber unit, extending it from zero to its full range. 

The result: the geothermal facility received vibration protection that met strict seismic standards, safeguarding its piping system from high-intensity earthquakes without interfering with thermal movement or risking damage.

Where Hydraulic Snubbers Work Best

Because of the ability to restrict and control sudden movements, snubbers are ideal for specific needs, such as:

  • Geothermal plants, where the buildup of steam could cause steam hammers in the pipeline.
  • Petrochemical plants, where sudden forces like pressure surges, thermal expansion, or seismic activity could impact system stability and safety
  • Power plants, where dynamic loads such as seismic events, steam hammers, or turbine trips could cause sudden pipe movements.
  • Nuclear plants, where seismic activity and system fluctuations can affect the movement of critical liquids and gases. 
  • High-vibration environments that aren’t always predictable
  • Seismically active zones that require restraint under load but flexibility at rest.

At the geothermal facility in California, our snubbers were necessary in ensuring the heat of the pipes didn’t cause misalignment of their route. Because of our hydraulic snubbers, these pipes can transport energy safely and without interruption to thousands of homes. 

Key Benefits of a Hydraulic Snubber

The benefits are visible the moment they are needed. Because of its design, a hydraulic snubber:

  • Transfers shock and vibration from the piping equipment to the building structure during dynamic events, absorbing the impact instantly.
  • Allows free movement under normal thermal expansion
  • Minimizes damage risk from water hammer or seismic activity
  • Has a fully customizable stroke and can be supplied with pipe clamps for specific load applications.
  • Can be easily and efficiently cycle tested for durability and code compliance

Engineer’s Take: Why Choose Our Hydraulic Snubbers 

Engineers and project managers trust hydraulic snubbers from Fronek/Anchor Darling and PT&P because they:

  • Meet ASME and seismic restraint codes.
  • Are manufactured to specific specs based on an engineer’s and project manager’s application needs.

Hold-Down Pipe Clamps with PTFE Slide Plates Offer Secure, Low-Friction Thermal Movement

test service nolan

HD-2 and HD-3 Hold-down Pipe Clamps

Allow Axial Movement While Maintaining Vertical Restraint

Pipe hold-down clamps secure the pipe in place while allowing it to expand, contract, and shift naturally without stress concentration or misalignment.

Thermal expansion can disrupt alignment, overstress anchors, and damage coatings, particularly on large-diameter pipes measuring 20 inches or more in diameter. Without proper restraint, pipe systems can buckle supports or shift pipe saddles, triggering high-cost field repairs.

In compressor stations, wastewater treatment facilities, pipeline terminals, petrochemical plants, and LNG terminals, slight misalignment can threaten structural integrity. Long lead times on specialized supports only aggravate the situation.

That’s why engineers choose pipe hold down clamps that install cleanly, eliminate the effects of stress, and account for thermal expansion.

HD-2 and HD-3 Pipe Hold Down Clamps with PTFE Slide Plates Manufactured by Piping Technology

Our HD-2 and HD-3 pipe hold-down clamps are designed to provide secure vertical restraint and controlled axial movement of the pipe.

These hold-down clamps are designed for pipes with diameters of 20 to 30 inches and are manufactured from carbon steel. The clamp saddle and base are lined with PTFE (polytetrafluoroethylene) and 25% glass fiber-filled slide plates, creating a durable, low-friction sliding surface.

The result: restrained vertical load with smooth axial movement, while restraining vertical and lateral movement in the piping system.

How it works:

  • PTFE-lined (or graphite) surface allows low-resistance axial pipe movement without binding or buckling
  • Glass fiber fill reinforces the sliding surface under load
  • Carbon steel body ensures long-term structural stability
  • Typically installs using a bolt-down configuration, minimizing the need for field welding

Case Study: Rush Delivery to South Dakota Natural Gas Pump Station

A natural gas pump station in South Dakota required large-diameter hold-down clamps that could withstand thermal cycling, vibration, and harsh outdoor exposure.

Project Specs:

  • Pipe Diameter: 20″ to 30″
  • Quantity: 22 custom-fabricated pipe hold down clamps
  • Material: Carbon steel with 25% glass-filled PTFE liners
  • Application Environment: Outdoor station, high-vibration compressor skid
  • Turnaround: One-week rush fabrication, shipped on time, zero field modifications

The hold-down clamps arrived installation-ready with clear labeling and documentation: no grinding, no guesswork, no schedule slip.

We pride ourselves on being the manufacturing leader for large-scale projects, providing rapid delivery to meet construction milestones. We offer a 24-hour emergency support hotline for critical situations:

Custom Pig Launchers Built for High-Pressure Pipeline Performance

test service nolan

24" x 30" diameter, 740 PSIG Pig Launchers and Receivers
24″ x 30″ diameter, 740 PSIG Pig Launchers and Receivers

Maintain Flow, Prevent Downtime, and Protect Pipeline Integrity

As debris builds up inside long pipelines, it becomes increasingly difficult for the media to flow. If left unchecked, this buildup can compromise safety and trigger costly maintenance shutdowns.

Pig launchers provide a proven and reliable inline solution. Allowing for the insertion of pipeline inspection gauges, custom pig launchers & receivers are engineered for cleaning, separation, and inspection. In some cases, our custom pig launcher systems let you maintain pipeline performance without depressurization, keeping operations online and flow rates steady.

How a Pig Launcher Works

A pig launcher is a pressure-rated chamber that safely introduces a pipeline inspection gauge, commonly referred to as a “pig,” into a piping system. Once loaded, sealed, and pressurized, the pig is pushed through the line by the flow of media or compressed gas. The pig removes debris, separates media, and/or inspects for defects along the way.

Each pig launcher & receiver unit includes:

  • Major barrel for pig loading and collection
  • Minor barrel that is inline with the main pipeline
  • Quick-opening closure for safe, quick, and reliable access to the pig when it’s in the launching and receiving process
  • Valves and flanges designed to maintain flow through the bypass line with pressure gauges, vents, drains, pig indicators, and more; all designed to ensure project-specific specs are maintained

When paired with a receiver, it forms a complete pigging system, ideal for routine maintenance, pipeline integrity checks, or product batching without interruption to operations.

Case Study Example: High-Pressure Pigging System Built to Spec

Adjustable Pipe Saddles for Stabilizing Heavy Horizontal Piping Under Dynamic Loads

test service nolan

30" Dia. Adjustable Pipe Saddle Supports Designed for an Oil Refinery

Designed to prevent deformation and reduce stress at key support points, adjustable pipe saddles deliver fixed, stable support where movement is not an option.

Chosen When Precision Elevation and Structural Rigidity Are Non-Negotiable

Heavy piping systems under load can shift, sag, or deform, especially when unsupported over distance or exposed to vibration, thermal change, or movement, putting your process-critical fixed equipment at risk . Adjustable pipe saddles are engineered to eliminate those risks. 

By locking the pipe into a fixed elevation and anchoring directly into structural steel or concrete, these supports maintain piping system alignment reduce localized stress prevent any long-term deformation in critical systems.

Why Engineers Choose Adjustable Pipe Saddles Over Adjustable Pipe Stands

Engineers will usually specify adjustable pipe saddles when systems require exact pipe elevation, concentrated load handling, and rigid structural anchoring that won’t shift under pressure. For projects where pipe supports must prevent movement entirely, rather than allow for it, saddles are the reliable, constructability built solution.

 

Adjustable Pipe Saddles vs. Fixed Pipe Saddles: What’s the Difference?

Adjustable Pipe Saddles

Adjustable pipe saddles feature a fixed-height saddle (the curved cradle that supports the pipe), but are mounted on adjustable vertical supports or stanchions. This allows the elevation to be fine-tuned during installation to match field conditions, which is ideal when construction tolerances, structural discrepancies, or elevation mismatches are likely.

How It Works:

  • A seamless center pipe section can be rotated to raise or lower the saddle height.
  • Pre-drilled base plates make anchor bolt installation fast and consistent.

Carbon steel construction with red oxide primer or hot dipped galvanized coating ensures corrosion resistance in harsh environments.

Fixed Pipe Saddles

Fixed pipe saddles are completely static supports. Both the saddle and its structural stanchion are built to a specified height, with no option field adjustability. They’re designed when exact elevations are known in the piping system, to achieve maximum stability and zero movement under load.

Case Study: Adjustable Pipe Saddles for an  Oil Refinery Retrofit in Michigan

When an EPC firm was retrofitting sections of a Midwestern oil refinery,  they needed the infrastructure  to support large process lines with varying elevations across aging foundations. We were able to design and manufacture  custom adjustable pipe saddles for 24″ and 30″ diameter piping, fabricated from carbon steel and coated with red oxide to withstand Michigan’s seasonal shifts.

Adjustable Pipe Saddle Product Specs:

  • Pipe Sizes: 24″ and 30″ OD
  • Support Height: Adjustable from 40″ to 42″

Demystifying Perceived Conflicts and Omissions in ASME B31.3

Industries go to great lengths in engineering analyses, construction/welding procedures and commissioning to assure public safety with high integrity final pressure boundary assurance of piping while paying only cursory attention in the codes to flange design and deployment.  Flanges are a break in the pressure boundary and thus, should receive constant focus in the codes.  Today’s high temperature flanges are virtually free of focus and remain a constant cause of process fires and hazardous leakage.

 

Additionally, constant threats to today’s elevated temperature ASME B31.3 piping pressure boundary integrity are

  1. Design Pressure and Temperature definition,
  2. Advanced pipe wall thickness calculations for high temperature, cyclic service
  3. Vibration,
  4. Expansion Joint design and troubleshooting,
  5. Mitered bend design,
  6. Branch area replacement,
  7. Hydrogen service,
  8. Low temperature brittle fracture.

Galvanized Knee Braces

Keeping Pipe Support Systems Stable, Even Under Lateral Load and Wind Stress

Unanticipated lateral loads from wind gusts to seismic tremors can quickly compromise pipe support systems in any projects. Structural instability around critical piping runs is a project risk that no project manager wants to explain. That’s where galvanized knee braces step in. These structural supports reinforce vertical pipe stands and structural steel, preventing sway, racking, or collapse during field events ranging from vibration control to water hammers.

How They Work: Braced to Resist and Built to Last

Galvanized knee braces function as diagonal steel members welded or bolted between vertical and horizontal components, forming rigid triangles that distribute and counteract horizontal forces. At Piping Technology & Products, we custom-fabricate galvanized knee braces from carbon steel and then “hot-dip galvanize” the entire unit for corrosion protection. This protects the knee braces from extreme weather conditions and exposure to saltwater and rain, which are often conditions seen at operating facilities.

The braces are prefabricated for standard layouts or designed custom to accommodate irregular geometries, offset loads, or tight envelope requirements. Once installed, they create a stable moment-resisting frame that ensures structural integrity for lateral loading.

Where They’re Used: Cross-Industry Structural Reinforcement

Galvanized knee braces are commonly deployed in:

  • Petrochemical plants: Pipe racks, platforms, and vertical supports

  • Power generation facilities: Turbine and cooling system infrastructure

  • Midstream terminals: Metering skids and loading platforms

  • Water treatment facilities: Pipe galleries and elevated walkways

  • Pulp & paper mills: Vertical piping columns under dynamic loads

Benefits at a Glance: Engineered Strength and Field-Ready Durability

  • Reinforces structures against wind, vibration, and lateral movement

  • Hot-dip galvanized for maximum corrosion resistance

  • Compatible with new construction and retrofits

  • Custom-fit to jobsite dimensions for fast install

  • Cuts down the risk of structural failure or pipe movement

  • Reduces field rework from instability or misalignment
