PE-RT – Al – PE-RT

GPP’s PERT-AL-PERT multilayer pipe is a kind of five layers pipe that combines the advantages of a metal and plastic pipe, eliminating the disadvantages of both materials at the same time. Both inner and layer are made of PERT material, enabling PERT-AL-PERT multilayer pipe to be used at 95℃ hot water. The aluminum core in the middle layer is absolutely diffusion tight, reliably preventing oxygen/gases from permeating into the pipe. The PERT-AL-PERT multilayer pipe compensates and reduces snap-back forces and heat-expansion during temperature changes.
