Large Diameter HDPE Solid Wall Pipe Extrusion Production Line

Product overview This production line is a heavy‑duty, high‑output system engineered to produce ultra‑thick‑walled, large‑diameter HDPE solid wall pipes (PE100 compatible). It combines high‑efficiency single‑screw extruders, a spiral‑distribution mold with in‑mold suction and internal cooling, a two‑stage hydraulic vacuum sizing tank, multi‑crawler traction, and chipless cutting — all coordinated by a centralized computerized control system for stable, continuous, highly automated production.

Applications

• Municipal and industrial water mains (large transmission lines)
• Drainage and sewer systems requiring high‑strength, large‑bore pipes
• Irrigation and agricultural mainlines
• Offshore and coastal drainage works, culverts, and industrial process piping where large diameters and thick walls are required

Core selling points

1. High‑efficiency extruders: The production line uses the JWS‑H series single‑screw extruders — engineered for high throughput. Their special screw‑barrel geometry produces ideal melt uniformity at comparatively lower melt temperatures, improving product quality and reducing thermal degradation.
2. Spiral distribution mold with in‑mold suction cooling: The die’s spiral distribution design ensures even material flow for large diameters. The integrated in‑mold suction internal cooling system, combined with low‑sag PE100 material, enables reliable manufacture of ultra‑thick wall sections and very large diameters.
3. Precision vacuum sizing & automated conveying: A two‑stage hydraulic open/close movable vacuum sizing tank provides accurate dimensional control. Independent multi‑crawler traction units and a chipless cutter are centrally coordinated by computerized control, delivering high automation, stable continuous production, and reduced manual intervention.
4. Optional wire‑rope tractor: For very large diameters, an optional wire‑rope traction device simplifies initial startup and reduces mechanical stress during the first pull‑in, improving reliability and operator convenience.
