HDPE Pipe for Water Supply
Key Features of HDPE Water Supply Pipes
- Non-toxic: The HDPE material is non-toxic and tasteless. It belongs to green building materials and has passed strict health tests, effectively improving water quality and ensuring it meets your needs.
- Low Flow Resistance: The smooth inner wall makes pipeline transportation easy. Under the same conditions, HDPE pipe’s delivery capacity can be increased by 30% as its roughness is much less than that of steel and glass-reinforced pipes.
- No Leakage: HDPE pipe is connected by butt fusion, socket fusion, and electrofusion, which means the strength of the joint point is higher than that of the pipe itself.
- Excellent Flexibility: Small diameter HDPE pipes can be coiled, and large diameter products can be slightly bent, making them more convenient for construction sites.
- Good Resistance Ability for Scratch: HDPE pipe has four times the wear resistance of steel pipe, which means a longer service life and better economic efficiency.
- Convenient for Construction: PE pipes can be installed in a variety of trenchless ways, making construction and installation very convenient.
- Long Life-span: Designed for 50 years of service life under rated temperature and pressure.
- Lower Operation and Maintenance Costs: HDPE pipes are not only convenient to transport and install but also greatly reduce workers’ labor intensity and improve work efficiency.
Applications of HDPE pipe for water supply
Urban Area Water-Supply Work System: Large diameter HDPE pipe is healthy and non-toxic, making it more suitable for urban water supply main conduits and buried tubes.
Replacement of Cement, Iron, and Steel Pipes: HDPE pipes are ideal for renovation projects as they do not require large area excavation. They can be widely used in the pipe network reconstruction of old towns.
Industrial Materials Transmission Pipe: HDPE pipes are used in various industries including chemical, chemical fiber, food, forestry, pharmacy, light industry, papermaking, and metallurgical industries for raw material conveying.
Landscaping Water Supply Network: Landscaping projects require a large number of water supply pipes. HDPE pipes are the best choice for their toughness and low costs.
