A-Type Variable Spring Supports for a Process Power Plant in Oklahoma

Type: Variable Spring Supports
Size: Rod Diameter 2” / Casing 8′ long & 3 1/8” Diameter
Material: Carbon Steel
Design: Operating Load 31,563 lbs., Installed Load 29,000 lbs., 0.82″ Downward Movement
Testing: Standard Load & Travel Tests

PT&P designed two standard PTP-4 size 210 A-type variable spring supports for a Process Power Plant in Oklahoma. The springs are fabricated from A36 carbon steel and with a hot-dipped galvanized finish. The springs are designed to accommodate a Hydro Test Load of 34,000 with operating Load of 31,563 and installed Load of 29,000, movement of 0.82″ downward. A Standard Load and Travel test was conducted on the variables prior to shipment. The springs utilize a rod diameter of 2” and the spring casing 8′ long and 3 1/8” in diameter.

Custom Designed Big Ton Spring Supports for a Propane Dehydrogenation Application in Texas

Custom Designed Big Ton Spring Supports for a Propane Dehydrogenation Application in Texas

Type: Big Ton Spring Supports
Size: 42″ x 24″ x 26 1/2″
Material: Carbon Steel
Design: 94,261 lb. Load & 0.085” Movement
Testing: Standard Load Tests

PT&P custom designed big ton spring supports for a propane dehydrogenation application at a chemical plant in Texas. The components within this assembly include the spring housing, coils, name plates, pressure plate, and load indicator. While both assemblies measure 42” L x 24” W x 26-1/2” H, it was modified based on independent specifications for operating loads and movement to accommodate a load of 94,261 lb. and 0.085” of movement. This type of support is ideal for applications, such as supporting pressure vessels that combine very heavy loads with thermal expansion because of the stability they provide. The big ton was tested in the load cell to insure proper operation throughout the entire working range of the coils.

Over 4,000 Cryogenic Pre-Insulated Pipe Supports Designed for LNG Service

Over 4,000 Cryogenic Pre-Insulated Pipe Supports Designed for LNG Service

Type: Pre-Insulated Pipe Shoe & Clamp Assemblies
Material: 304 L Stainless Steel | Protective Coating | Micarta® Insulation
Design: 20″ L x 36″ W x 75″ H | 56″ Dia. Pipeline | -459°F
Testing: Load & Pull Tests

PT&P designed over 4,000 supports for LNG service in Texas. These pre-insulated pipe shoe and clamp assemblies were custom designed for cryogenic temperatures with special low temperature grade NP500CR Micarta® insulation. This type of Micarta® consists of a glass fabric with a special formulated epoxy resin. It has excellent physical properties at operating temperatures down to -459°F. It has very low thermal conductivity and has been produced specifically for use in cryogenic applications. The shoes pictured are fabricated from 304 L stainless steel with a protective coating and are designed for a 56″ diameter pipeline. The shoes measure 20″ long, 36″ wide and 75″ high. This project included supports varied in pipe sizes from ¾” to 56″ diameter. A load test was performed prior to shipping this rush order.
