HDPE water supply pipes, namely high-density polyethylene water supply pipes, are made of high-density polyethylene as the main raw material and processed by extrusion for transporting various types of water, such as domestic water and industrial water.
It has the following outstanding characteristics:
- Excellent Corrosion Resistance: It has good tolerance to most chemical substances and can resist the erosion of various acids and alkalis in water. This ensures long-term stable operation in complex water quality environments and greatly extends the service life.
- High Toughness and Strength: HDPE water supply pipes possess both high toughness and relatively high tensile strength. This makes them less likely to rupture or deform when facing external impacts, ground settlement, etc., effectively guaranteeing the safety and reliability of the water supply system.
- Smooth Inner Wall: The inner wall of the pipe is extremely smooth, with low water flow resistance. This not only improves water conveyance efficiency, reduces energy consumption, but also decreases the adhesion of impurities in the water to the pipe wall, minimizing the risk of pipeline blockage.
- Hygienic and Non-toxic: Made of environmentally friendly high-density polyethylene material, it contains no harmful substances and will not cause secondary pollution to the transported water. It meets national drinking water hygiene standards and can be safely used for domestic drinking water transportation.
- Reliable Connection: Common connection methods include electrofusion connection and hot melt connection. Through these two methods, the pipe and fittings can achieve integrated connection. The strength of the connection is higher than that of the pipe itself, with good sealing performance, effectively preventing water leakage.
- Superior Low-temperature Resistance: In low-temperature environments, it can still maintain good flexibility and mechanical properties, and is not prone to brittle fracture due to low temperatures. It is suitable for water supply projects in cold regions.
HDPE water supply pipes have a relatively rich variety of specifications. The nominal outer diameter generally ranges from 20mm to 1000mm, and the wall thickness is reasonably designed according to different pressure levels and application scenarios. Standard lengths are usually 6m, 9m, 12m, etc., and can also be customized according to customer requirements.
Due to its many advantages, HDPE water supply pipes are widely used in urban water supply systems, cold and hot water transportation within buildings, industrial water circulation systems, agricultural irrigation water supply, and water supply projects in special fields such as mines and oil fields.
