The pex-al-pex pipe(multilayer pipe,PAP pipe) we can supply include:
1) Aluminum layer is longitudinally welded (by ultra-sonic wave method) in an over-lapping way. 2) Aluminum layer is BUTT-WELDED by argon arc welding method. 3) Aluminum layer is BUTT-WELDED by LASER welding method.

The PEX-AL-PEX composite capitalizes on the corrosion and chemical resistance
of plastic and the pressure capacity of metal by laminating the aluminum
layer between layers of plastic. The resulting tubing is non-corroding,
bendable for form stability, flexible, and resists most acids, salt solutions,
alkalis, fats, and oils.
PEX-AL-PEX pipe (PAP pipe) is widely used in residential and commercial
plumbing and in pressure service on compressed air and compressed gas
systems. PEX, and PEX-AL-PEX pipe are typically joined with metal fittings.
