Plastic composite pipe extrusion line is mainly composed of extruder, five layer coextrusion die, vacuum sizing, cooling, hauling, cutting, reeling, etc. Thanks to the multi layer coextrusion technology, it can extrude the PEX and PE-RT anti oxygen pipe with the diameter range from 16 to 160mm. Also, it adopts the extrusion die and the dedicated screw for the oxygen resistant material EVOH. The highest production speed can reach over 20m/min. By exchanging different dies, we can produce the oxygen barrier pipe with distinct specifications. In addition, the five layer pipe is covered with PU foam layer and PE corrugated pipe layer. The winding machine can be coiled into disk, which is not only convenient for installation and long distance transportation of hot water, but also helps cut down the heat loss.
