HDPE Hollow Wall Spiral Pipe Extruding Machine with 200-3000mm Pipe Range Single-Screw Extruder for High Ring Stiffness
Product Overview
Huashida manufactures advanced large-diameter hollow wall winding pipe production lines with extrusion capacities up to 4000mm, designed for:
- HDPE Hollow Wall Winding Pipes
- Anti-Static Mine Ventilation Pipes
Featuring specialized connectors (electrofusion belts/heat-shrink sleeves) for rapid, cost-effective installation.
Key Advantages
Structural Superiority
- High ring stiffness (SN4-SN16) and impact resistance
- Lightweight (30% lighter than concrete pipes) with 50-year service life
Performance Excellence
- Resists creep deformation, external pressure, and chemical corrosion (acids/alkalis/salts)
- Smooth inner wall (Manning coefficient n=0.009) for optimal flow
Economic Benefits
- 40% lower installation cost vs. traditional concrete/ductile iron pipes
- No heavy machinery required for deployment
