Big Diameter HDPE Hollow Wall Corrugated Pipe Extrusion Line with Single-Screw Extruder for Municipal Underground Drainage System

Double Wall Corrugated Pipe Production Line is a new type of high-speed water-cooled corrugated pipe production 
line developed and designed by ourselves based on advanced foreign technology. Mainly using polypropylene (PP) or 
high-density polyethylene (HDPE) as raw materials. Production of single and double wall corrugated pipes. Due to its 
unique structure, this pipe has the advantages of light weight, good impact resistance, strong corrosion resistance, and
 cold and heat resistance. It is widely used in urban drainage (water supply), geographical infiltration, construction water 
supply and drainage, PEF, wire and cable laying, bridge steel cable sheath, agricultural irrigation, and other fields.

The DWCP series high-speed corrugated pipe forming machine adopts a closed water-cooled structure, and the mold 
base drives the left and right modules to move within the closed curve. The mold base adopts a gear dynamic structure, 
which has the advantages of automatic compensation for mechanical wear, smooth operation, low noise, long service life, 
and highsynchronization. The unique design of the circulating water circuit has high reliability, good cooling effect, and 
low water impact in the pipeline, which improves the reliability of continuous production of pipes and ensures the surface 
forming quality of pipes.
