PVC Double Pipe Extrusion Line It is mainly used to produce 16mm to 40mm PVC pipes and 16mm to 63mm PVC pipes. The entire production line consists of a cone double host, a double-out mold, a double-tube vacuum box, a double traction cutting machine, a turning frame and so on. Two tubes can be produced at the same time to achieve greater production efficiency. The processing flow of this line is as follows: PVC powder + additives-mixing-material feeder-twin screw extruder-mold and calibrator-vacuum forming.

This Double Pvc Pipe Line is widely used for producing pvc water supply pipe, drainage pipe  and high voltage cable protection pipe. With PVC pipe mold, it could also produce PVC pipe. It is consist  of SJSZ series extruder, mold, vacuum tank, spraying cooling tank, haul-off, cutting machine, stacker, and can produce PVC pipe from mixed powder directly.

This double pipe extrusion line uses special designed screw and mould, which makes it easy forming, even plasticization, high capacity, stable running and easy operation.

Production process

PVC powder + additive → mixing → spring feeding → twin screw extruder → mould and calibrator → vacuum forming machine → haul off machine → cutting machine → stacker
