Why use a cryogenic support for a cold pipeline?

February 17, 2011

The types of insulation are broken down per their temperature ranges. In general, high temperature supports use different types of insulation than the low temperature supports. Cryogenic means that this particular support should be used on cold pipelines.

 

What is a cold shoe?

February 11, 2011

A cold shoe refers to a support component which incorporates an insulating material that attaches directly to the pipe and also functions as a load bearing component transferring the load to a point outside of the insulating enclosure.

What is a pipe anchor support?

February 1, 2011

A pipe anchor support is a rigid device that completely restricts pipe movement in all three dimensions while bearing the weight, side, and thrust loads. It is designed to prevent essentially all pipe rotation and displacement at the point of application.

What are the properties of polyurethane?

November 2, 2010

Polyurethane is a light-weight material used primarily in low-temperature applications to provide both a load bearing function and insulating function for the pipe. Some of the specific design parameters of polyurethane are as follows:

  • Temperature Range-Ambient to -300 DEG. F
  • Compressive Strength-220 PSI to 911 PSI (Dependent on Density)
  • Tensile Strength-200 PSI to 800 PSI

When would one use piping cold shoes?

In general, insulated pipe shoes are used whenever one is trying to incorporate a support which provides both load carrying ability and insulating properties simultaneously. Normally cold pipe shoes are used in cryogenic applications where operating temperatures are below 32 degrees F.

Why is a clamp support used in cold lines?

Insulated clamp supports may be used in cold applications where the insulation and clamp combination act together to provide a load carrying member and simultaneously provide insulation for the pipe. In some applications, the clamp would be fixed directly to the pipe surface and subsequently insulated with the pipeline.
