Qingdao Huashida's large-diameter hollow-wall winding pipe equipment ranks among China's earliest HDPE hollow-wall winding pipe production lines. Backed by strong technical expertise and extensive experience in installation, commissioning, and operation, this equipment can manufacture both hollow-wall winding pipes and antistatic gas-extraction pipes for mining applications. The pipeline system uses specialized fittings-such as electrofusion belts and heat-shrink sleeves-ensuring easy assembly, reliable performance, and cost-effective construction.
The pipes are hot-wound from high-density polyethylene with an I-beam-style wall, combining the strength of steel with the flexibility of plastic. Available in diameters from 300 to 1200 mm, these pipes are ideal for municipal sewer and drainage projects and provide a high-quality alternative to concrete, cast-iron, and conventional pipes.
Equipment Specifications:
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.
Pipe Advantages
• High ring stiffness and external-pressure resistance
• Lightweight yet high impact strengt
• Resistant to acids, alkalis and salts
• Service life ≈ 50 years
Machine Features
• Dual-extruder co-extrusion: square pipe + adhesive melt
• Multi-axis drive winding box for stable operation
• Composite die head for rotary forming
