Size selection of the PEX-AL-PEX pipe Diameter: 3/8",1/2",5/8",3/4" and 1" Wall thickness: 2mm Material: PEX-AL-PEX, both the inner and outer layer cross-linked AL layer thickness: 0.2 mm Maximum working pressure: 10 bar (PN 10) Maximum operating temperature: 95°C Features of the PEX-AL-PEX pipe The outer and inner layers of the PEX-AL-PEX pipe are made of PEX (silane crosslinking polyethylene) The intermediate aluminum layer reinforces the structure of the pipe, thus forming and retaining a particular pipe shape. It can withstand temperatures up to as high as 95°C and a working pressure of 1.25MPa, thus meeting design requirements for high temperature radiation heating. The PEX-AL-PEX tube has a large aluminum layer that allows it to bear high loads. It has all the characteristics of a metal pipe, making it safe and reliable. The thickness of the aluminum layer is evenly distributed, and the its stiffness is uniform. The hoop stress and shape change evenly, thus ensuring a reliable connection between the pipe and pipe fittings. The product features smooth end, uniform pipe wall and excellent roundness.
