PEX-b/AL/PEX-b metal multilayer pipe, external layer color yellow, internal layer in PEX-b (cross-linked polyethylene), intermediate layer in aluminum longitudinally welded (butt-butt) with laser/TIG technology and external layer in PEX-b (cross-linked polyethylene).

The intermediate layers of glue homogeneously join the aluminum layer to the PEX layers. The presence of the aluminum layer guarantees a safe barrier against oxygen and other gases, as well as giving the product excellent resistance to crushing. .

Suitable for the transport of gas for domestic use, thermal conductivity of the pipe 0.43 W/(m K) and coefficient of linear thermal expansion 0.026 mm/(mk).

Available in diameters 16x2, 20x2, 26x3, 32x3 and also with yellow corrugated covering sheath for anti-crushing and anti-UV protection, temperature range of the Multigas System (pipe and fittings): 5÷70 °C.

Maximum operating pressure of the Multigas System (pipe and fittings) 0.5 bar.

The Multigas System involves the combined use of the G999 series multilayer pipe with RM-GAS fittings and allows the creation of systems for the transport of methane gas and LPG for domestic use. The temperature range of the Multigas System (pipe and fittings) is 5÷70 °C, maximum operating pressure of the Multigas System (pipe and fittings) 0.5 bar.
