Key Features

1.Superior Structural Strength: Unique double-wall design with corrugated outer wall provides excellent ring stiffness (up to SN16), while the smooth inner wall ensures efficient fluid flow.

2.Exceptional Corrosion Resistance: HDPE material offers outstanding resistance to chemicals, acids, alkalis, salts, and various organic solvents, with a service life exceeding 50 years.

3.Lightweight yet Strong: Only 1/8 the weight of concrete pipes and 1/5 that of cast iron pipes, significantly reducing transportation and installation costs.

4.Excellent Flexibility: Good impact resistance and flexibility allow adaptation to uneven ground settlement, with superior seismic performance.

5.Environmentally Friendly: 100% recyclable material, pollution-free during production and use, meeting environmental requirements.

6.Outstanding Abrasion Resistance: Smooth and wear-resistant inner wall minimizes scaling, maintaining high flow capacity over time.

Product Advantages

Easy Installation: Uses socket connection or thermal fusion jointing, with installation speed 3-5 times faster than traditional pipes.

Lower Total Cost: Although unit price is slightly higher, savings in transportation, installation and maintenance reduce lifecycle costs by over 30%.

Excellent Adaptability: Wide working temperature range (-60℃ to +60℃), suitable for various climatic and geological conditions.

Superior Hydraulic Performance: Low friction coefficient (Manning's n=0.009), providing 30% greater flow capacity than concrete pipes of same diameter.

Low Maintenance: No regular anti-corrosion treatment needed, with minimal daily maintenance costs.

Application Scenarios

1.Municipal Engineering: Urban stormwater drainage systems, sewage collection systems, road drainage.

2.Construction Projects: Building subsurface drainage, basement drainage, roof rainwater discharge.

3.Industrial Applications: Factory wastewater discharge, chemical pipelines, mine drainage.

4.Agricultural Irrigation: Farmland drainage, water-saving irrigation systems.

5.Power & Communication: Cable protection conduits, optical fiber communication ducts.

6.Special Applications: Landfill leachate collection, wastewater treatment plant networks.
