Piping Technology designed hot shoes with sliding bases for a power plant in Mississippi. The assemblies will be installed on 28″ diameter pipe and include 1-1/2″ thick calcium silicate insulation. Manufacturing fabricated these supports from galvanized carbon steel with a polyethylene base. They are capable of an operating load of 7,200 lb., temperatures up to 1,200 degrees F and an axial movement of +/- 4-1/2″. The shipment was met three days prior to the critical field need date.

The compact spring is ideal for applications with large loads and limited space.
– Minimizes excessive loads on sensitive equipment
– Same load for smaller working range while consuming 25-50% less space
– Ideal for locating under equipment flanges
– Reduces design time, maintenance cost and accidents
These springs are the solution for satisfying excessive nozzle loads for load sensitive equipment, such as pumps, compressors, turbines, blowers, heat exchangers, pressure vessels and storage tanks. In addition, the entire spring support can be made from corrosion resistant stainless steels or other suitable alloys making it ideal for combating aggressive environments like seawater, marine air and harsh chemicals.

PT&P designed G-Type variable spring supports for a paper manufacturing plant in Minnesota. The variables are comprised of two standard spring housing coil subassemblies joined together with an intermediate bridge assembly. The bridge assembly is customized to match existing site conditions which allows for use in applications with limited space or interferences. The variables are fabricated from carbon steel with a hot-dipped galvanized finish. The assemblies were designed for a total operating load of 1,348 lb. with an upward design travel of 0.8013″. Each assembly underwent a standard load test prior to shipment.

U-Type constant spring supports were designed to support ducts in an acid plant. The constants are fabricated from carbon steel, galvanized and painted for extra protection against corrosion. The U-type constants are designed to support piping from below. The base plate is 25-7/8″ wide and bolted directly to the top of the steel or floor. The assemblies measure 84″ in length and 22-1/2″ in height. They only have vertical movement subjected by 6-1/2″ total upwards travel and are capable of supporting a 13,489 lb. load. The constants underwent standard spring testing prior to shipment.
