300+ Cryogenic Insulated Pipe Supports Designed For An Lng Pipeline

Type: Cryogenic Insulated Supports
Size: Range: 6″ to 24″ Dia. Pipe
Material: Carbon Steel | Hot-dipped Galvanized | PUF
Design: 15,000 – 30,000 lb. Load | -112 F | +/- 2″ Movement

Over 300 pre-insulated pipe supports were custom fabricated for a cryogenic pipeline at an LNG facility in Louisiana. High density polyurethane foam was used for insulation, with thicknesses ranging from 2” to 4”. The cold shoes are for pipe diameters ranging from 6” to 24” and are fabricated from carbon steel with a hot-dipped galvanized finish. They are designed for temperatures down to -112°F, movements of +/-2” and operating loads ranging from 15,000 to 30,000 lb. Standard quality control tests were performed prior to shipment.

Micarta Block Assemblies Designed For A Vessel Application In Texas

Type: Insulated Support – Micarta® Block Assembly
Size: 2″ H x 12″ W x 81″ L
Material: Micarta® | PTFE, 25% Glass-filled
Design: -454°F | Visual / Dimensional Tests

PT&P designed Micarta® block assemblies for placement beneath the saddle support of a vessel at an oil refinery in Texas. These insulated supports measure 2” x 12” x 81” and include PTFE, 25% glass-filled material bonded to the top of the Micarta®. Micarta® consists of glass fabric with an epoxy resin, which provides great insulating characteristics and superior physical properties. The blocks are designed to prevent cryogenic temperatures down to -454°F from transferring past the base of the support to the supporting steel or foundation. Visual and dimensional tests were performed prior to shipment.

Variable Spring Supports For A Propane Dehydrogenation Unit In Texas

Type: Variable Spring Supports
Size: Accommodate Elevation Difference up to 11′-5″
Material: Carbon Steel | Hot-dipped Galvanized
Design: 20,000 lb. Load | 4,700 lb./in. Spring Rate

PT&P designed and manufactured over 50 variable spring supports for a propane dehydrogenation unit in Texas. The spring cans, rods, welded beam attachments, turnbuckles and clevises are fabricated from hot-dipped galvanized carbon steel. The variables can accommodate an elevation difference up to 11’-5” from the bottom of the steel to the connection of the pipe. They were designed for an operating load of 20,000 lb., a spring rate of 4,700 lb./in. and 0.007” upward movement. Standard load testing was conducted prior to shipping.
