200-3000mm Computerized HDPE Hollow Wall Winding Pipe Production Line with Hollow Wall Structured Design

The HDPE Large Diameter Spiral Wound Pipe Extrusion Line is engineered for manufacturing HDPE spiral-wound pipes, also known as Krah pipes, structural wall pipes, or spiral interlock pipes.

These pipes are widely used in municipal sewerage, drainage, stormwater management, and infrastructure projects. With their high ring stiffness, excellent corrosion resistance, lightweight structure, and convenient installation, they provide a durable and cost-effective alternative to traditional concrete and cast iron pipes.

1. Municipal sewerage and drainage systems
2. Infrastructure and civil engineering projects
3. Industrial wastewater discharge systems
4. Culverts and stormwater drainage systems

1. High ring stiffness and excellent structural strength.
2. Lightweight construction with reliable load-bearing performance.
3. Excellent resistance to acids, alkalis, salts, and other corrosive substances.
4. Outstanding resistance to long-term creep deformation.
5. Long service life of up to 50 years under proper operating conditions.
6. Environmentally friendly, recyclable, and corrosion-resistant.
7. Energy-efficient extrusion system with an optimized screw design for efficient plasticization.
8. Dual-extruder configuration for profile extrusion and adhesive bonding during spiral winding.
9. Advanced spiral forming unit with multi-axis transmission and a rotary forming head for uniform pipe wall construction.
10. Automatic saw cutting system for precise pipe length control.
11. Fully automated PLC control system with multi-point control and dual-screen operation for coordinated management of extrusion, forming, winding, and cutting.
