Feature And Application
Key features:
1.Due to its low-temperature tolerance,our DWC corrugated hdpe pipe for sewerage is suitable for cold climates.
2.The corrugated structure makes our DWC pipe enables use in soft soil or quicksand foundations, adapting to diverse geological conditions.
3.Ring stiffness up to SN10 grade, with strong compressive resistance for deep burial and geological settlement.
4.Because of the abrasion and impact resistance,our DWC pipes ideal for stormwater or sewage discharge containing sediments.
5.Our DWC pipes have good chemical resistance,such as acids, alkalis, and salts, suitable for industrial drainage and sewage.
6.Joints ensure a tight seal without leakage.
7.Smooth inner wall enabled low friction coefficient for efficient drainage.
8.Our DWC pipes are lightweight,easy to transport and install, reducing overall project costs (labor + logistics).

Applications:
1.Municipal Engineering and Residential Areas: Underground drainage for rainwater and sewage.
2.Industrial Zones, Wastewater Treatment Plants and Landfills: Drainage and sewage discharge.
3.Agricultural Irrigation and Flood Drainage: Water conveyance and dewatering.
4.Power and Telecommunication Cable Protection:  DWC pipe can be used as conduit sleeves.
5.Ventilation, Fluid Transport and Drainage in Chemical and Mining Industries.
6.Well Casing for Drilling Projects (Perforated Double-Wall Corrugated Pipe).
7.Brine Transport in Salt Industry and Water Conveyance in Fisheries.



Details

The corrugated annular structure of the outer wall significantly enhances the pipe's ring stiffness, improving its load-bearing capacity against soil pressure.
