HDPE Double Wall Corrugated Pipe Making Machine DWC PIPE MAKING MACHINE

The fully automatic plastic double wall corrugated drain pipe extrusion making machine uses HDPE / PP as raw materials. The inner wall of the double wall corrugated pipe produced by this production line is very smooth and flat.

And the outer wall is trapezoidal corrugated shape. This kind of double wall corrugated pipe has the characteristics of good corrosion resistance, high insulation, small flow resistance etc. as the ordinary plastic pipe, but also because of special inner and outer wall hollow ring structure, it has the advantages of high rigidity, light weight, high pressure resistance, good toughness, abrasion resistance, impact resistance, not easy damage, convenient construction, low installation cost, long service life etc.

The characteristics of fully automatic plastic double wall corrugated drain pipe extrusion making machine:

Extrusion Machine

Both outer layer and inner layer are extruded
inside die head. Each material flow channel inside die head is placed evenly. Each
channel is after heat treatment and mirror polishing to ensure material flow smoothly. Also die head provides compressed air
between both layer.
Calibration sleeve is used to cool inner layer to form smooth and flat pipe inside. Pressure water flows inside calibration sleeve
to have good cooling effect. Vacuum is created on calibration sleeve surface when producing big diameter pipe, ensure inner pipe roundness.
