Single-wall & Double-wall PP PE PVC plastic corrugated pipe extrusion line, Plastic Corrugated Pipe Making Machine

PVC Single-Wall Corrugated Pipe Production Line

PVC Single-walled Corrugated Pipe based on PVC as the main raw material, made by extrusion blow molding. A new product developed in 1970s. PVC Single-walled Corrugated Pipe uses its ring groove structure to have both rigid PVC Pipe’s rigidity and hose’s flexibility, so that the pipe has the characteristics of soft within rigid. It can be used to transport certain liquids and gases and as embedded wire casing.

HDPE Double-Wall Corrugated Pipe Production Line

HDPE Double-Wall Corrugated Pipe is a new pipe with a ring structure outer wall and smooth inner wall. It was first develop successfully in the early 80s in Germany. After more than 10 years of development and improvement, it has been very mature in the production process and the use of technology. Because of its excellent performance and relatively economical cost, it has great promoted and widely used in Europe and the United States and other developed countries. In China, HDPE Double-wall corrugated pipe’s promotion and application is in the uptrend stage, and the technical indicators have reached the use of standards. Double wall corrugated pipe wall color is usually blue and black; some brands will use the yellow wall.

Description of plastic corrugated pipe extrusion line, Plastic Corrugated Pipe Making Machine​:

Control system: this Single-wall & Double-wall corrugated pipe line canbe adopts Siemens professional PLC control system, 15 "large color touch screen human-machine interface, high automation, reliable running, easy operation, remote communication function which can realize remote fault diagnosis and rule out the possibility.

Extruder: High speed and efficiency single screw extruder/ twin screw extruder is specially designed for extrude PP PE/PVC material. Grooved barrel, equipped with the lower noise blower, high speed and hard gear reducer. The inner and outer layers of the corrugated pipe are independently fed material by two extruders. It can make the inner and outer layers produce different material and guarantee high efficiency extrusion. We can also use one extruder to produce same color, same material corrugated pipe, that to save the cost of machine.

Corrugator forming machine: Corrugator forming machine is adopted horizontal structure with chain type transmission, equipped with open water cooling system also with cooling blower system. It greatly increases the production speed. Mold Blocks moving adopts advanced synchronous upper and lower mechanical drive system. It assures moving accuracy and plastic pipe quality stability. Advanced self-lubricating system makes the forming molds and mold plates abrasions minimize and greatly extend the service life.

Die head: The die head has two structures: Independent extrusion structure and co-extrusion structure.the extrusion die head has two channel structure, nitriding and polishing handling, special designed mouth molds, suitable for different material and different ring stiffness pipe production. The die head has water and air circular system respectively and form the double wall corrugated pipe by cooling water. The special molds structure assures the inner and outer layer wall thickness even and forming stability.

Cutting machine: By electrical, pneumatic joint control, it can make smooth pipe incision, dustless cutting, simple and sensitive operation becomes true. It can implement fixed- length automatically cutting which matched over loading fixed-length equipment.
