HDPE Water Supply Pipe is made from high-density polyethylene (PE100) and is one of the most commonly used pipe materials in modern municipal water supply and drinking water transmission systems. This product boasts excellent flexibility, corrosion resistance, and impact resistance, enabling it to adapt to complex geological environments. It is widely used in urban water supply, rural drinking water projects, and industrial water transmission systems.
Compared to traditional metal pipes or PVC pipes, HDPE water supply pipes are safer, more durable, and have a longer service life (up to 50 years or more).

HDPE material itself is non-toxic and odorless, suitable for drinking water transmission systems, and meets international hygiene standards. Its stable molecular structure provides the following characteristics:
Corrosion Resistance: Unaffected by acids, alkalis, and salts
High Flexibility: Adaptable to foundation settlement
Impact Resistance: Not easily broken in low-temperature environments
UV Resistance: Suitable for outdoor environments
Smooth Inner Wall: Reduces head loss and increases flow rate
HDPE water supply pipes can be customized according to project requirements:
Diameter range: DN20 – DN1800mm
Pressure rating: PN6 / PN10 / PN16 / PN25
Standards: ISO 4427 / EN12201 / ASTM
SDR rating: SDR11 / SDR17 / SDR21
Color: Black with blue stripes (standard)
HDPE pipes utilize heat fusion technology, using a welding machine to ensure a completely sealed system:
Butt Fusion
Electrofusion
Flange Connection
