Product Description:

50-800mm Large Diameter HDPE Double Wall Corrugated Pipe Extrusion Machine Line


Application of the pipes produced:

electricity wire sleeve, urban water supply and drainage system, agricultural irrigation pipe, underground filtration irrigation and the water supply or drainage system in buildings, etc.


Characteristics of the pipes produced:

 Light weight, good performance of shock resistance, high rigidity, corrosion-resistance, cold and hot resistance


Characteristics of the machine:

Mould and Auxiliary Machine: The mould die is of high precision and the mould blocks are changeable. There are two cooling modes to the mould block, by water and by fan. The planetary cutting machine is of high cutting precision; SIMENS human-machine interface control system realizes high automation.

Extruder: The extruder can be designed according to the different materials; HDPE material uses high efficiency single screw extruder, the PVC material uses conical double-screw extruder.


  1. Two high efficient co-extrusion single screw extruders

2.It adopts excellent screw and new groove sleeve design,
which makes the extruder with bellow advantages: high plasticization rate,
smooth melt, stable production process, 
and enable the inside and outside layer of the pipe to use different materials
3. Corrugation forming block is made by special alloy material. It has high precision, 
intensity and outstanding heat emission.
4. Nitrogen treatment of the mould surface. There is wall thickness adjusting device
in the mouth mould and can produce pipes of different raw materials.
It has a flaring function, which can reduce the investment and enhance efficiency.
6. The production line adopts advanced Simens PLC control system
, with human-machine interface operating system, has high automaticity, easy operation.
