Shunfang manufactures large-diameter HDPE pipe systems for two duties: steel-wire-reinforced PE pressure pipe for water transmission and supply, and structured-wall HDPE pipe for gravity drainage and sewers. Very large pipes can be produced on site where transport is the constraint.
Pressure pipe
Steel-wire-reinforced PE pipe for water transmission and supply. Reinforced PE pressure pipe for raw-water, municipal and industrial supply lines.
Pressure pipe
Composite pressure pipe for water mains up to DN1600.
Pressure pipe · 2.6 m and above
Spiral-wound pressure pipe for mains of 2.6 m and above.
Gravity pipe
Large-Diameter Structured-Wall HDPE Pipe. Spiral-wound structured-wall HDPE pipe for stormwater, sewer, culvert and outfall lines.
Structured-wall · Type A
All-polyethylene gravity pipe with smooth inner and outer walls.
Structured-wall · Type B
Steel-reinforced gravity pipe for very large diameters and high ring stiffness.
| Your project | Recommended pipe | Why |
|---|---|---|
| Pressure main up to DN1600 | Steel Wire Reinforced PE Composite Pipe | Standard pressure classes 0.4–2.5 MPa, 3.0 MPa by project review |
| Pressure main 2.6 m and above | Large-Diameter Reinforced PE Pressure Pipe | Made by spiral winding for pressure pipe of this size |
| Gravity sewer or stormwater line that needs a smooth outer wall | Type A: Hollow-Wall Spiral-Wound Pipe | Smooth inside and outside |
| Gravity drainage at very large diameter or high ring stiffness | Type B: Steel-Wire-Reinforced HDPE Structured-Wall Pipe | Steel-wire-reinforced ribs; SN12.5 and SN16; published sizes DN160–DN5000 and project-specific manufacture up to 6 m |
