HDPE Double Wall Corrugated Pipe Extruder Machine for Municipal Water Supply


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

Double-Wall Corrugated Pipe Production Line Components

Extruder:
Single-screw extruders have a simple structure and low cost, making them suitable for applications with low production requirements.
Twin-screw extruders offer excellent plasticizing, mixing performance, and extrusion stability, resulting in higher production efficiency.

Corrugator:
Enables the installed corrugated forming module to operate continuously and stably, providing the vacuum and cooling functions required for corrugation.

Cooling System:
Typically uses water cooling, air cooling, or a combination of both.
Water cooling offers high cooling efficiency, quickly reducing pipe temperature, improving production efficiency and pipe quality. Air cooling is relatively simple and low-cost, making it suitable for applications with low cooling speed requirements.

Cutting Equipment:
A planetary cutter or fully automatic corrugated pipe cutter is used to precisely cut double-wall corrugated pipe, achieving high cutting accuracy and smooth cuts.

Control System:
A PLC control system ensures precise control and coordinated operation of all production line components.
