Multilayer pipes for gas installations
We offer a range of multilayer pipes ideal for gas distribution systems. Our range includes pipes made from both PE-Xb/Al/PE-Xb and PE-Xc/Al/PE-Xc.
We understand that every installation requires the most practical solution, which is why our pipes are available in both bars and rolls.
Multilayer pipes can be used with TRIDENT 5G00 SERIES fittings.

Description
Multilayer pipe is characterized by a 5-layer structure in which a butt-welded aluminum layer is enclosed between two layers of cross-linked polyethylene (PEX) and fixed to the latter by two layers of adhesive.
Thanks to this feature, multilayer pipe represents a perfect combination of the properties of plastic (cross-linked polyethylene with high mechanical resistance) and ductile metal (highly flexible aluminum), in which the qualities of PEX are added to those of aluminum, giving life to a product with extraordinary and multiple qualities.
PEX confers chemical resistance, corrosion resistance, lightness, hygiene and guarantees a very smooth and polished contact surface, thus reducing pressure drops and avoiding encrustations.
The presence of aluminum makes it possible to shape the pipe with extreme simplicity in order to significantly speed up installation and prevent the passage of oxygen inside the pipeline.
The pipe can be used in methane or LPG supply systems and is combined with the fittings of the TRIDENT series in the gas use systems proposed by General Fittings.
