Pipe for cryogenic liquid PERMA PIPE

XTRU-THERM®, our "State of the Art" preinsulated piping system for fluids from cryogenic temperatures up to 250ºF. The extruded HDPE jacket results in a completely bonded system that moves as a single unit for maximum efficiency and service life.

XTRU-THERM® is a process driven product, developed to eliminate problems inherent in foam injected systems. The pipe is insulated using a special spray applied continuos feed insulating process which works in line with our extruded high density polyethylene plastic material. The JACKET remains flexible at low temperatures and has a higher temperature rating than PVC. The HDPE jacket has been specifically designed to bond to the insulation. Designed for both above and underground insulated pipe applications. The hardness, tensile and flexural strength, toughness, diameter and thickness of the jacket are controlled.

The foam insulation is spray-applied and rises, unrestricted, to its final thickness. The free rise allows cell structure of the foam to be uniform in all directions. Because the foam is spray-applied and not injected, XTRU-THERM® is guaranteed to be 100% void-free. The blowing agent (HCFC, a gas that expands the foam and creates cell structure) does not dissipate from the cell like other water-based agents. Therefore, the cell structure and thermal value is maintained and the foam will not shrink.
