PAP(PEX-AL-PEX) pipe is composed of a five-layer structure consisting of inner and outer layers of polyethylene, a middle layer of longitudinally welded aluminum pipe, and two layers of adhesive between the aluminum pipe and the polyethylene. It has the comprehensive advantages of metal pipe and pure plastic pipe - excellent corrosion resistance and chemical resistance.

Compared to plastic pipe, PAP pipe can endure higher pressures and higher temperature, as well as excellent performance in oxide isolation;

Compared to metal pipe, PAP pipe is much lighter, easier to apply(ease to cut and bendable), low cost(saving fittings), etc.
