Sliding Cryogenic Insulated Supports For A 60&Quot; Diameter Vapor Line
Sliding Cryogenic Insulated Supports

These sliding cryoshoes are fabricated from carbon steel with 2″ thick polyurethane insulation. The polyurethane is 20 lb. density, which has a compressive strength of 500 psi and a tensile strength of 600 psi. The cold shoes are designed for temperatures as low as -300°F and for loads up to 3,500 lb. They will be used to support a 60″ diameter low temperature vapor line in a Texas facility.

Replacement Constant Spring Supports with Neoprene Coating for a Highly Corrosive Application at a Salt Water Cooler Tower

October 19, 2010
Original Supports (Not Fabricated By Pt&Amp;P)

PT&P received a call to inspect spring supports in operation at a salt water cooler tower. It was quickly determined that replacement supports would be needed due to the heavy corrosion of the original supports not fabricated by PT&P.

A total of 40 constant and variable spring supports were fabricated as replacements. Each support was sealed with a neoprene coating over a hot-dip galvanized finish instead of stainless steel. This type of finish will ensure a much longer life-span. The spring supports ranged in loads from 800 lb. to 15,000 lb. with various travel ranges.

Variable Spring and Cro-Moly 3-bolt Clamp Assemblies for a Power Generation Facility

October 5, 2010

Variable Spring And Cro-Moly 3-Bolt Clamp Assemblies For A Power Generation Facility

The variable spring and clamp assemblies are fabricated using a combination of carbon steel for the housing and internal components, spring steel for the spring coils, and Cro-Moly (A-387 GR. 22) for the high temperature 3-bolt clamps. This pipe hanger assembly is an example of PT&P’s standard variable spring design wherein multiple coils are arranged in series to produce adequate load carrying capacity and coil deflection to compensate for the anticipated pipe movement. These particular assemblies are capable of an overall load range of 9,320 lb. to 15,970 lb. with a total travel range of 5″. All pipe hanger assemblies underwent standard load and travel testing, 100% deflection testing, and load cell calibration before shipping to a power generation facility.
