HDPE drainage pipes have the following performance advantages:
1. Physical properties
· Strong corrosion resistance :HDPE material has stable chemical properties and can resist the corrosion of various chemical media, making it suitable for harsh environments.
· Wear-resistant: The inner wall is smooth, with a low friction coefficient. Its wear resistance is four times that of steel pipes, making it suitable for transporting fluids containing solid particles.
· Good impact resistance: The low-temperature brittleness temperature is extremely low, and it can be safely used within the temperature range of -40℃ to 60℃. It is not prone to cracking during winter construction.
· High ring stiffness: By adopting double flat-wall structure, steel belt reinforcement or double high-bar reinforcement, etc., the ring stiffness of the pipeline is enhanced, enabling it to withstand considerable internal and external pressure.
· Good flexibility: It can be bent, adapt to uneven settlement of the foundation and ground deformation, reduce the use of joints, and lower the risk of leakage.
2. Hydraulic performance
· Low water flow resistance: The inner wall is smooth with a low roughness coefficient, allowing water to pass smoothly, which can reduce head loss and improve drainage efficiency.
3. Construction and Maintenance
· Reliable connection: Hot-melt or electrofusion connection is adopted, with the joint strength being higher than that of the pipe body, good sealing performance, and less prone to leakage.
· Convenient construction: Light in weight, easy to move and install, it can shorten the construction period and reduce construction costs.
· Low maintenance cost: Corrosion-resistant, wear-resistant, long service life, reducing the frequency of maintenance and replacement.
4. Economy and Environmental Protection
· Good economic performance: Low comprehensive cost, long service life, and significant long-term economic benefits.
· Environmentally friendly and recyclable: The materials are recyclable and meet environmental protection requirements.
