SIFFO HDPE Double Wall Corrugated Pipe Features
High Ring Stiffness and Compression Resistance: The corrugated structure of the outer wall significantly enhances the ring stiffness of the pipe, enabling it to withstand larger external loads and making it suitable for deep burial projects.
Flexibility and Impact Resistance: HDPE material has good toughness, can adapt to uneven foundation settlement, has strong impact resistance, and is not easily broken.
Corrosion Resistance and Aging Resistance: It has excellent resistance to acids, alkalis, soil corrosion, and microbial erosion, with a service life of over 50 years, and requires no anti-corrosion treatment.
Lightweight and Convenient Construction: Weighing only 1/8 of concrete pipes and 1/5 of cast iron pipes, it has high transportation and installation efficiency, reducing construction costs.
Smooth Inner Wall and Strong Flow Capacity: The inner wall has a low coefficient of friction (Manning coefficient is approximately 0.009), resulting in high drainage efficiency and preventing scale buildup.
Environmentally Friendly and Good Sealing: The socket connection provides strong joint sealing, preventing sewage leakage and soil contamination; the material is recyclable.
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.
