HDPE Hollow Wall Winding Pipe Production Line with 200-3000mm Pipe Range, PLC Control, and Hollow Wall Structure

Qingdao Huashida's large-diameter hollow-wall winding pipe equipment is one of the earliest HDPE hollow-wall winding pipe production lines developed and manufactured in China. With strong technical capabilities and extensive experience in installation, commissioning, and production, the equipment can produce both hollow-wall winding pipes and antistatic gas-extraction pipes for mining applications. Using specialized fittings (electrofusion belts and heat-shrink sleeves), the pipeline system offers easy connection, reliable performance, and economical construction.

The pipes are hot-wound from high-density polyethylene with an I-beam-structured wall, delivering steel-like strength while maintaining the flexibility of plastic. With diameters ranging from 300 to 1200 mm, they fully meet the requirements of municipal sewer and drainage systems and serve as an excellent replacement for concrete, cast-iron, and traditional pipe materials.

Machine Scope:
Pipe Diameter: 300-1200 mm
Applications: Municipal sewer and drainage systems; replacement for concrete and cast-iron pipes

Extruder

The system uses a PE/PP single-screw extruder. The feeding section of the extrusion unit is equipped with forced water cooling and a grooved barrel, significantly reducing the power consumption of the main drive motor. The extruder features a large L/D ratio screw (30-38:1), offering strong material adaptability and excellent plasticizing performance. For customers using recycled materials or adding calcium carbonate, specially designed screws can be customized upon request.

Spiral Forming Machine

Equipped with a composite die head, the machine forms pipes through spiral rotation. With a compact structure and unique design, it ensures high-quality products.

Forming Machine

High-quality workmanship and compact design with stable transmission.

Control System

Professional PLC control system with intelligent centralized operation.
