PE-AL-PE Multilayer Pipes
PERT-AL-PERT Multilayer Pipes
Risong multilayer pipe is a kind of five-layers' pipe that combines the advantages of a metal and plastic pipe and eliminates the disadvantages of both materials at the same time.Both inner and layer are made by PE(X) material, which made multilayer pipe can be used at 95℃ hot water, the aluminum core in middle layer is absolutely diffusion tight, which can reliably prevents oxygen/gases from permeating into the pipe. The multilayer pipe can compensate and reduce snap-back forces and heat-expansion with changes of temperature.
Risong multilayer pipes mainly include: PE-AL-PE multilayer pipes for cold water and gas, PERT-AL-PERT multilayer pipes for cold and hot water, PEX-AL-PEX multilayer pipes for cold and hot water.
Risong is a leading provider of multilayer piping systems. Besides multilayer pipes, Risong is also able to provide compression type brass fittings, press type brass fittings, various of installation tools.
