hdpe coil pipe

    HDPE coil pipes are bent into a U-shaped or spiral pipeline form, mainly used for conveying liquids or gases. Has good flow characteristics, smooth inner surface, and low friction loss. Its unique hot melt connection method ensures the sealing and stability of the pipeline, suitable for various complex irrigation systems. The main component of HDPE irrigation pipe roll is high-density polyethylene, which has a high molecular weight and crystallinity. Therefore, its hardness, tensile strength, wear resistance, and resistance to environmental stress cracking are superior to ordinary polyethylene.These pipelines have strong UV resistance and are suitable for urban water supply, landscape water supply, industrial raw material transportation pipeline network, and industrial wastewater discharge.

1. Urban water supply and drainage system:

• HDPE water pipe roll, for its good corrosion resistance and long life, is often used in urban water supply pipeline system to ensure the safe delivery of drinking water.
• In the drainage system, the HDPE pipe roll can effectively collect and treat the sewage, and its inner wall is smooth, reducing the flow resistance and improving the drainage efficiency.

• HDPE coil pipes are widely used in the field of farmland irrigation, especially in water-saving irrigation systems, such as drip irrigation and sprinkler irrigation systems, to ensure the uniform and efficient distribution of water to each field.
• Its excellent low temperature resistance makes the HDPE pipe and fittings can work normally in the cold winter and ensure the normal growth of crops.

• In the chemical, pharmaceutical, food and other industries, HDPE coil pipe is used to transport a variety of corrosive media, such as acid, alkali, salt, etc., and its corrosion resistance ensures the long-term stable operation of the pipeline system.
• The HDPE pipe roll is also often used as a protective casing for power cables and communication lines, protecting the cables and lines from damage to the external environment.

• HDPE coil pipes are also used in high-end fields such as oil and gas pipelines and submarine pipelines, and their excellent performance and reliability have been widely recognized.
• And, as well, the flexibility and impact resistance of the HDPE pipe roll in situations that requires flexible connections, such as vibration or expansion joints.
• At the same time, there are many applications ares in mobile home, container home, construction home, elevated bridges and other water transportation.
