Pex-al-pex multilayer pipes for gas systems

BRIEF DESCRIPTION

Multilayer pipes made of cross-linked polyethylene with a smooth yellow outer surface, a smooth white inner one (both made of PEX-b) and a middle layer which consists of aluminium foil with an oxygen barrier function combined with the PE layers (inner and outer) through specific adhesives.

The diameters range (OD) goes from 16 to 32 mm. Pipes are delivered in coils and pipe lengths, with or without the yellow coating of corrugated pipe. They find application in the gas distribution for domestic appliances.
