Description

MINGDA aluminum-plastic PPR composite pipe comprises of five-layer mutual-extruded structure, interior layer is food degree PE-RT, exterior layout is of PPR, the middle one is 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 PPR 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 PPR tubing, its connecting is the same as that of PPR pipe.
