HDPE Double Wall Corrugated Pipe Making Machine DWC PIPE MAKING MACHINE
HDPE corrugated pipe making machine extrusion line production machine plastic pipe extruder
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 double wall corrugated pipe is generally connected by the expansion socket and the sealing ring.
This can effectively prevent the impact of thermal expansion and contraction.
The double wall corrugated pipe is widely used in the fields of highway, railway roadbed, subway engineering, waste landfill, tunnel, green belt, sports field and high water content caused by the slope protection and other drainage areas.
