Steel Strip Reinforced HDPE Spiral Corrugated Pipe SN8
SN8 | ID300-2600mm
Steel Strip Reinforced HDPE Spiral Corrugated Pipe with SN8 ring stiffness combines the flexibility of HDPE with the strength of steel reinforcement. The spiral corrugated structure provides excellent load-bearing capacity while maintaining flexibility for ground settlement adaptation. ## Product Features This pipe features a unique composite structure with HDPE inner and outer walls bonded to a galvanized steel strip reinforcement layer. The SN8 grade offers reliable ring stiffness for standard depth installations. ## Technical Advantages - **High Ring Stiffness**: SN8 grade provides ≥8 kN/m² stiffness for reliable structural performance - **Corrosion Resistance**: HDPE material resists chemical corrosion and biological attack - **Long Service Life**: Designed for 50+ years of continuous operation - **Easy Installation**: Lightweight compared to concrete pipes, reducing installation costs ## Typical Applications Widely used in municipal drainage, sewerage systems, and industrial wastewater applications where reliable, long-term performance is required.
