Product Description
Peculiarities of HDPE Double-Wall Corrugated Pipe:
1. Strong Resistance to External Pressure: The outer wall features a ring corrugated structure, which significantly enhances the ring stiffness of the pipe, thereby improving its resistance to soil loads.
2. Low Project Cost: Under equivalent loading conditions, an HDPE double-wall corrugated pipe requires a thinner wall thickness to meet performance standards, resulting in approximately 50% savings in raw materials compared to solid wall pipes of the same material specifications.
3. Easy Construction: Due to its lightweight nature, the pipe is easy to handle and connect, facilitating rapid installation and straightforward maintenance.
4. Low Friction Coefficient and High Flow Rate: The smooth inner wall reduces friction, allowing for a higher flow rate compared to other pipes of similar diameter.
5. Excellent Low-Temperature and Impact Resistance: With an embrittlement temperature of -70°C, the pipe maintains its integrity under typical low-temperature conditions without requiring special protective measures during installation.
6. Superior Chemical Stability: HDPE molecules are non-polar, making them resistant to degradation by most chemical substances, with the exception of a few strong oxidants.
7. Long Service Life: In the absence of direct exposure to ultraviolet sunlight, the pipe can last over 50 years.
8. Outstanding Wear Resistance: The wear resistance of HDPE pipes is several times greater than that of steel pipes.
9. Appropriate Deflection: A certain length of HDPE double-wall corrugated pipe can withstand slight deflections in the axial direction, remaining unaffected by minor ground settlements.
