G-Type Variable Spring Supports Designed for a Coker Replacement Project

PT&P fabricated PTP-6 G-type variable spring supports for a coker replacement project in Kansas. The variables are comprised of two standard spring housing 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. They are 50″ in length, designed for an operating load of 15,000 lb. and fabricated from carbon steel with a hot-dipped galvanized finish. All variable assemblies underwent standard load and spring testing prior to shipment.

14 Foot Long Sway Struts Custom Designed for a Gas Facility in Canada

PT&P custom designed sway struts for a pipeline in a natural gas facility located in Canada. The sway struts are fabricated from carbon steel and include a painted finish for corrosion protection. The lengths range from 106″ to 173″. They are capable of supporting loads up to 8,000 lb. and are designed to restrain movement in one direction while providing movement due to thermal expansion or contraction in another direction.

54″ Dia. Pre-Insulated Pipe Shoes Custom Designed for a Pipeline in Texas

February 21st, 2015 Comments off


Pipe Shields/PT&P designed and manufactured pre-insulated pipe shoes for a 54″ diameter pipeline in a chemical processing plant in Texas. The hot shoes are custom designed with a wide base to accommodate lateral movement and axial movements of +/- 4 1/2″. We designed the hot shoes to include additional bolting along with bolting torque recommendations order to help prevent slippage of the pipe inside the pipe shoe. We designed the supports to accommodate vertical loads up to 22,200 lb. and temperatures up to 1800°F. The outer part of the shoe was manufactured of hot-dipped galvanized carbon steel while the inner insulation material is 4″ thick high density calcium silicate insulation.

F-Type Variable Spring Supports Designed for an LNG Facility

PT&P manufactured F-type variable spring supports for an LNG facility in Colorado. The variables installed heights range from 10-5/8″ to 21-1/16″. The F-Type pipe hanger assembly is used to support the pipe from below and are typically mounted to concrete pads via anchor bolts or welded to structural steel. The various springs shown are designed for operating conditions ranging from loads of 633 lb. to 6510 lb. As with all of our variable supports, these were quality checked with a 100% spring coil deflection test and a load cell calibration to set the assembly at the prescribed installed load.

Heavy Duty Yoke U-Bolt Pipe Clamps Designed for a Pipeline in Canada

These custom heavy duty Fig. 43 yoke u-bolt pipe clamps are designed for a pipeline in Canada. The yoke clamps are designed for 42″ diameter pipe sizes and are fabricated from hot-dipped galvanized carbon steel. They are designed to support a load of 27,500 lb. PT&P supplied a total of 28 assemblies in three weeks for this project. These yoke clamps went through finite element analysis and performance tests prior to shipment.

108″ Dia. Storage Tank and Containment Tank Designed for a Chemical Plant in Texas

January 11th, 2015 Comments off


Sweco Fab., a division of PT&P, designed and fabricated this 108″ diameter storage tank that will be submerged inside a containment tank for a chemical plant in Texas. The storage tank is fabricated from 1/2″ thick SA516-70 carbon steel and is 240″ in length. The containment water tank measures 295″ L x 124″ W x 128″ H. The storage tank is designed for 100 PSIG at 130°F internally and 15 PSIG at 130°F externally. The storage tank was hydro tested for 1 hour at 150 PSI and a full radiography test was done prior to shipment.
