Corrugated Pipe Production machine line Introduction

Corrugated pipe extrusion machine can produce 9mm to 1200mm OD/ID corrugated pipe, which is widely used as cable protect cover, medical transfer pipe (small size corrugated pipe); gas transfer, water transfer (big size corrugated pipe), etc.

Corrugated pipe machine consists of:

1. Extruder

a. We choose extruder type according to different material. We usually use conical double screw extruder for PVC material while single screw extruder for PE/PP material.

b. We choose extruder model according to pipe size & mould design. For example, PE 9mm to 25mm corrugated pipe, we choose SJ65/30 single screw extruder for high speed design or SJ55/30 single screw extruder for normal speed design.

c. We choose extruder QTY according to pipe design. For single wall corrugated pipe, we use one extruder; for double wall corrugated pipe, 2 sets of extruders. For example, for PE 160mm single wall corrugated pipe production machine, we choose SJ75/33 single screw extruder; for double wall type we choose SJ75/33 single screw extruder + SJ65/33 single screw extruder as well as SJZ45/90 conical double screw extruder for small PVC single wall corrugated pipe extrusion.

According to client’s requirements, our extruder could be controlled by SIEMENS PLC with SMATAC HMI.

2. Pipe extrusion die + corrugated pipe forming die

a. Pipe extrusion die have the same function like normal solid wall pipe dies, making the melted plastic into round shape.

  1. But there is difference, because its wall thickness is very thin, so it will be blown with air when going into forming die, in case of very bad shaping and sizing, which is a difficult control part.
  2. Corrugated pipe forming die is usually made of aluminum/aluminum-alloy. According to pipe size & forming machine type, it has different designs of setting on forming machine. And there are different cooling types according to line speed design, such as normal speed production speed, fan cooling, high speed production speed, water cooling.
  3. Our designed forming die can realize on-line belling, which is convenient for pipe connection.

3. Forming machine

Forming machine is used to set the forming die and make the forming die continuously work.

4. Cutting machine + stacker or winding machine

a. Usually for small size (9mm to 110mm) corrugated pipe, it is equipped with winding machine, single disc winder or double disc winder, both are ok. For high speed, we suggest double disc winder.

b. Like 75mm, 90mm, 110mm pipes, they can be cut into short ones, such as 9m, 6m etc. It is better to have it equipped with cutting machine + stacker because cutting efficiency is higher than that of winding type.

Corrugated Pipe Production line Application

Single wall corrugated pipes

Single wall corrugated pipes are widely used in many fields such as auto wire, electric thread-passing pipes, circuit of machine tool, protective pipes of lamps and lanterns wire, as well as air conditioner and washing machine tubes, etc.

Double wall corrugated pipe 

It is mainly used for large water delivery, water supply, drainage, sewage discharge, exhaust, subway ventilation, mine ventilation, farmland irrigation, etc. under the pressure of less than 0.6MPa. such as:
1 Municipal Engineering: used as drainage pipe.
2. construction works: used as building rainwater pipes, underground drainage pipes, sewage pipes, ventilation pipes.
3. railway, highway communication equipment: used as communication cable, optical cable protection tube.
4. industry: widely used in chemical, hospital, environmental protection industries such as sewage pipes.
5. agricultural garden project: used in farmland, fruit tea garden, and forest belt drain.
6.Road Engineering: used as the seepage and drain pipe of railway and expressway.
7. Mine: used as mine ventilation, air supply, drain pipe.
8. double walled bellows: can do saline, highway seepage, drainage pipe.
9. golf course, football field project: used as a golf course, football field of infiltration, drainage pipe.
