U-Type Constant Spring Supports Designed for a Power Plant

Type: Constant Spring Supports
Material: Carbon Steel | HDG | PTFE, 25% Glass Filled
Design: 8,200 lb. Load | 11-1/2″ Total Travel
Testing: Standard Load and Travel Test

PT&P designed and manufactured 48 constant spring supports for a power plant in Mexico. The constants pictured above are Fig. 200 U-type constant spring supports fabricated from A-36 carbon steel and include PTFE, 25% glass filled slide plates bonded to the load flange. The supports are 39″ H x 26″ W x 80″ L and are designed for operating loads up to 8,200 lb., with a total travel of 11-1/2″. These are horizontal constants designed to support piping from below in conjunction with a pipe saddle. All the constants went through standard load and travel testing per MSS Standards prior to shipment.

Variable Spring Supports for a Furnace application at an Ammonia Plant

Type: Variable Spring Supports
Material: Carbon Steel | Red-Oxide Primer | 304 SS
Design: 3,000 lb./in.
Testing: Load Test

PT&P custom designed variable spring support assemblies for a furnace application at an ammonia plant. The furnace springs are fabricated from carbon steel and painted with a red-oxide primer to help prevent corrosion. The pipe clamps are fabricated from 304 stainless steel. They are designed to support a cold load of almost 3,000 lb./in. while operating in an area where temperatures are higher than ambient. There were a total of 173 assemblies fabricated for this project, 152 variable hangers, 3 constant spring supports, 6 ball joint rigid struts, and 12 rigid rod hangers. Special load tests were performed prior to shipping.
