Pex-Al-Pex multilayer pipess two types determined by its welding technology, i.e overlap and laser, it is a five layer composite pipe, with aluminum layer in the middle, outside layer material is PE(X)/PERT/PE, inside layer is PE(X)/PERT/PE material, each layer are bonded by heat adhesive, extruded out under high temperature and high pressure, it bears advantages of both plastic and metal, good pressure-bearing performance, hard and flexible, anti-corrosion, safe and sanitary, good mechanical performance, heating-resistant, oxygen-free, low heat expansion coefficient, light in weight, easy for installation, long service life, and aluminum involves overlap-welded and butt-welded process, can be used for cold water, hot water, gas, etc.
