Cryogenic transport of fluids and/or gases in oil and gas pipelines is often problematic as the low temperature of fluids or gases entering the pipeline leads to substantial shrinkage of most pipe materials, thereby generating significant thermal stress. While numerous attempts have been made to accommodate for thermal stress, new difficulties arose with such solutions.

PERMA-PIPE offers XTRU-THERM, POLY-THERM, and MULTI-THERM the most economical and maintenance-free system for LNG pipelines that require safe, reliable, and leak-free solutions to withstand operational stresses and displacements while also regulating thermal forces.
