Medium layer of aluminum lastic composite pipe is welded aluminum band, and inner and external layers are all made of polyethylene. Special purpose hot melting adhesive is used , and extrusion molding method is adopted for composite of pipe.Pressure resistance of metal pipe and corrosion resistance of plasitc pipe are combined together on the pipe. Thermal conductivity: 0.*5w/(mk); Coeffient of thermal expansion: 0.**5mm/(mk); Bending radius: >5D(d refers to outer diamter of pipe ) Medium temperature *0~*5c; Gas(oxygen) permeability 0; Inner wall of pipe smooth , small fluid resistance , and roughness is0.***4mm; Other good performance of antistatic , long sevice life
