Gussets are added reinforcement plates used to strengthen the overall structure of the shoe and provide either extra load carrying capacity or added strength when the pipe shoe is used as a guide or anchor.
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.
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.
Cryogenic Supports (Cold Shoes) with Permali Insulation
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.
Cold Insulated Pipe Anchors with Axial Stops
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
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.
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.
