Pexb al pexb pipe making machine is used to produce 5-layer overlap welding pex al pex composite pipes. Pipe diameter:½“，5/8”，¾“,1”,1-1/4“ or bigger up to 2-1/2”。Pipe producing process:Al strip uncoiling-inner glue and plastic layer extruding- outer glue and plastic layer extruding- pipecooling device- pipe coiling device. The produce multi-layer composite al-pexb pipes are mainly used as underfloor heating pipes in floor heating system.
The thin layer of aluminum in PEX-AL-PEX tubing acts as an oxygen barrier, preventing oxygen in the air from penetrating the system and rusting cast iron system components.
