50-160mm PPR Pipe Extrusion Line

Repol PPR (Polypropylene Random Copolymer) is. used to produce pipes and tubing for a variety of. domestic and industrial hot and cold water. applications. It offers all the advantages of plastics.A pipe extrusion line consists of different parts. An extruder converts raw plastic material into a continuous tubular melt by extrusion through an annular die. The molten pipe then proceeds through a sizing or calibration bench (which adjust its dimensions) to a cooling tank.Extrusion production line usually consists of main machine, auxiliary machine and control system. ① Host. The main equipment for plastic extrusion molding is the extruder, which is the host. It mainly includes extrusion and feeding system, transmission system, heating and cooling system, and control system.
