Aluminum-plastic PPR Composite Pipe comprises of five-layer mutual-extruded structure,interior layer is food degree PE-RT(PE),exterior layout is of PP-R,middle one is of longitudinal superposition-welded aluminum layer,which isolates each kind of liquid from penetration.It integrates in excellent high-temperature resistant performance for aluminum-plastic composite pipe and less distortion after heated while having reliability for PP-R tubing thermal melting connection.so it preferably settles down shortcoming of higher cost for aluminum-plastic composite tube joint and more linear expandability coefficient for PP-R tubing,its connection is the same as that of PP-R tubing.
