PEX-AL-PEX Multilayer Pipes for Gas

PEX-AL-PEX multilayer pipes are a revolutionary product for gas market. They are proven to be more cost-effective, easier and faster to install, as well as to have superior characteristics and benefits as compared with traditional gas pipes. The PEX-AL-PEX pipe comes with 5 layers. The inner and outermost layers are PEX and central core layer is overlap-welded aluminum. They are bonded by hot melt adhesives.

Pipe Colors
Inner layer: black
Outer layer: Yellow, gray
Executive Standard: GB/T 18997.1, ISO 17484-1, AS 4176.8
