PT&P designed and fabricated eighteen graphite slide plates for a refinery project in India. These plates are made of graphite sheets with thicknesses of 6mm and 12mm. The overall dimensions of the plates are 3/8″ x 19-11/16″ x 19-11/16″ and 3/8″ x 61″ x 61″. The plates will be tack welded on top of big ton spring supports in the refinery to minimize frictional effects.

PT&P recently fabricated 22 Fig. 190 Type 3 riser clamps for suspending the vertical runs of pipe at the central power plant in Puerto Rico. The clamps are designed for 17″ and 24” pipes and have an overall length of 71″ and 87” respectively. Both designs have a bar stock size of 1.75″x10″ and load bolts of 2.75″ diameter. Utilizing gusset plates at the clamp’s bend radius allowed for the smallest, yet sufficient clamp stock size for the specified loads. The smaller clamp has an operating capacity of 14,000 lbs while the larger operates at 20,500 lbs. Chrome-Moy 387 Grade 22 bar stock was used with A193 Grade B7 bolting to accommodate high temperature operating conditions.

Sweco Fab. Inc. recently manufactured 16 injection spray nozzle assemblies from INCO 625 material for a specific pressure application. Each nozzle is made up of a 1½ S/160 pipe. The quill construction is clog proof and utilizes the turbulence created by its unique design to achieve distribution of the injected liquid into the product flow.

PT&P recently designed and manufactured a support assembly with two PTP-2 Type C spring hangers and a special clamp support. The springs are designed for an 8,500 lb load and a maximum travel of 1″. The entire pipe hanger assembly, with a net weight of 860 lbs, was fabricated from Carbon Steel and A-387 GR. 22 Chrome. The springs were calibrated to determine the exact spring rate prior to adjusting to customer specifications.

Piping Technology and Products, Inc. fabricated 4702 carbon steel shoes for various pipe sizes ranging from 2” to 10”. As per customer request, the shoes are designed to accommodate 30 PSI compressive strength. A three-coat paint system was applied for corrosion protection. All supports were liquid dye-penetrant tested at 5% of welds.

PT&P recently manufactured 1,520 PTP-2 and PTP-4 spring hanger assemblies designed specifically for a furnace application. These custom variable springs have welded components as opposed to bolted components found in standard assemblies. Due to the space limitation within the furnace, the spring coils were set in a welded housing which allows for the springs to be closely oriented within a smaller spatial envelope. The pipe hanger assemblies are made from carbon steel, consisting of variable spring, rod, and riser clamp components. Instead of galvanizing, the assemblies were coated with a red-oxide primer due to the high temperature operating conditions of the furnace. This prevents the possibility of molten zinc (from the galvanizing process) contaminating the furnace tubes.
The springs are designed for loads of 143 to 660 lbs. and for total travel ranging from 3/4 to 2″. Each assembly was pre-assembled to ensure free movement throughout the spring’s travel range before welding the bottom closure plate. Prior to shipment, all assemblies were calibrated to determine the exact spring rate and then were set to the customer’s designated cold load position. These springs are then located and installed into the furnace based on the spring rate.

PT&P was called on by an energy center in Oklahoma to inspect failing pipe shoes designed for temperatures ranging from 650 to 1065 °F supplied by another company. After thorough inspection, PT&P’s field service representatives concluded that the problem was due to the existing pipe clamps’ inability to firmly grip the pipe during expansion. This exposed the pipes to atmospheric moisture, resulting in both heat loss and deterioration. To alleviate the situation, PT&P designed secured pipe clamps that were bolted and torqued such that the entire pipe shoe would move with the pipe’s expansion. PT&P’s field service team also provided on-site installation of the replacement pipe shoes. The entire process involved stripping of the existing damaged insulation, removal of the failing supports, and installation of new pipe shoes and insulation.
Over 160 pipe shoes were engineered, manufactured, and installed for this energy center. The fabricated pipe shoes, designed for pipe sizes ranging from 12 to 28″ in diameter, are equipped with special base plate and slide bearing plate combinations which allowed axial movement from 1/2″ to 7″ and lateral movement up to 10 1/2″. In addition, they were designed to support a maximum vertical and lateral load of 38,000 lb. and 7,600 lb. respectively.

Piping Technology & Products, Inc. has designed and manufactured over 177 tons of supports for the Chad/Cameroon Development Project in Chad, Africa. Adjustable Base Supports designed to support pipe size ranging from 3 to 18″ in diameter were one type of the many supports fabricated for this project.
Each of the hot-dipped galvanized pipe stands has an 8″x8″ base plate and a midrange height of 12″. The pipe stands allow for a maximum travel of +/- 3″. These supports provide for easy adjustment in the field when supporting pipe trunnions on concrete pads or foundations. In addition, these pipe stands have a major advantage when the exact installation heights are not known at the remote job site.
Other supports including constants and variables spring hangers, rigid rod hangers, structural steel, FRP pads, and pre-insulated pipe supports were also manufactured in a range of different specifications and materials.
