PT&P custom designed pre-insulated pipe supports with polyurethane insulation for cryogenic temperatures in a light hydrocarbon production facility in Texas. A total of 59 cold shoes were fabricated from A36 carbon steel with a hot-dipped galvanized finish. The cold shoe assemblies range in diameter from 24″-48″ and were designed to support loads ranging from 17,000 to 31,000 lb. Standard Q.C. and dimensional tests were performed prior to shipment.

PT&P custom designed pipe clamp assemblies for a partial oxidation unit in a synthetic gas plant located in Texas. The pipe clamps were fabricated from alloy A387 and coated with a special paint for high temperatures. The assemblies were designed with supportive structures for pipe sizes ranging from 2″ to 16″. Standard quality control inspection and tests were conducted prior to shipment.

PT&P custom designed sway struts for a chemical plant located in Texas. The sway struts and rod hangers are both fabricated from carbon steel. The overall length of the support assemblies’ range from 31″ to 83″ and are capable of supporting loads up to 1,750 lb., with an operating temperature of 1100°F and 1 1/2″ of vertical movement. The sway struts are designed to restrain movement in one direction while providing movement due to thermal expansion or contraction in another direction.

PT&P custom designed pipe hanger and clamp assemblies for a flue-gas desulfurization application in an energy facility located in Kansas. The assemblies are designed for pipes ranging in size from 2-1/2″ to 6″ in diameter, and are capable of a 650 lb. operating load. Materials include tube steel, fig. 92 washer, fig. 122 all threaded rod, fig. 30 turnbuckle, fig. 40 weldless eyenut and fig. 70 pipe clamp.

PT&P designed spring loaded stainless steel roller stands for a wastewater treatment plant. The rollers were custom designed for ease of assembly to support a 30″ diameter pipeline. They include eight springs in two spring housings and are designed for 1,000 lb. load. The base plate is 18-3/4″ x 13″ and the BOP is 10-3/16″. Roller stands are used to support pipelines that expand and contract longitudinally in the axial direction and where vertical adjustment is not necessary.

PT&P manufactured F-type variable spring supports for a chemical processing plant in Texas. The variables are designed with an internal guide and for a movement of 0.09″. They are designed for a 5,350 lb. cold load and 5,450 lb. hot load. Because these springs had to be capable of withstanding a hydro-test in excess of 33,000 lb. (which substantially exceeded the standard maximum hydro-test of 18,000 lb.), special collars were used in conjunction with the standard travel stops. These collars are designed to absorb the large hydro load by relying on the high strength characteristics of the load flange and housing components of the assembly while essentially bypassing the threaded internal components.

PT&P manufactured Fig. PTP 100-E constant spring supports for a steam methane reformer plant project in Thailand. The constant springs are designed for a pipe operating temperature from 650°F to 1250°F and an operating load of 3,355 lb. with a movement of 13″ upward. The constants are fabricated from carbon steel and painted with an epoxy for high temperatures. Standard load and travel test were completed prior to shipment.
