Double Wall Corrugated Pipe Extrusion Line

Double Wall Corrugated Pipe Extrusion Line
Sevenstars Machinery this line is used to produce Double wall corrugated pipes. it has two units of singles screw extruder Raw material is PE/PP granule/pellets.This machine can use PP PE material to produce big diameter double wall corrugated pipe.The pipe has light weight,strong impact resistant capability,high ring stiffness and corrosion resistance. And widely used in threading pipe, drain pipe, power pipe.
Double wall corrugated pipe is mature product which has the advantage of low weight, low cost, anti-corrosion, good ring stiffness
and flexibility. The product is mainly used in urban drainage and sewage systems. The HDPE double-wall corrugated pipe extrusion
line has the advantages of high output, stable extrusion and high degree of automation.

Extruder
The extruder is consist of screw, barrel, vacuum automatic feeder, hopper dryer, gearbox and motor. Spiral screw with mixing section, which improve the output and plasticization effect. Special for PE/PP material efficient extrude. Water cooling system with automatic temperature control is at the material inlet port of the barrel. The hopper dryer adopt drying and storing material integrated design, also with automatic temperature control and intelligent display. All the parts be made by reputed manufacturer and provided by reputed supplier.

Water Cooling Corrugator 
Corrugator is used to place and move corrugated mold. Vacuum is created to absorb outer layer into corrugated mold to formcorrugate shape. By moving corrugated mod, pipe is also pulled out from corrugator.
The horizontal structure layout of the corrugated pipe forming machine ensures higher rigidity, lower center of gravity, and smoother operation.
