High Density Polyethylene Pipe for Water Supply is a flexible plastic pipe for municipal water supply and drainage systems, water treatment piping systems, industrial water supply and drainage systems, rural or agricultural irrigation systems. It is made of thermoplastic HDPE (PE100, PE4710), 100% new food grade virgin material imported from Borealis, making it non-toxic, green and safe for potable water transportation. In addition its excellent flexibility allows the polyethylene pipe to be coiled and makes trenchless installation safer with butt-welded joints.


ZHSU high-density polyethylene water supply pipe has an elongation at break of more than 500%, high adaptability to uneven settlement of the pipe foundation and excellent seismic capacity.


HDPE pipe materials are non-toxic, green and safe with no heavy metal additives. High-density polyethylene water pipes made from virgin-grade polyethylene materials are safe for transporting potable water.


Excellent flexibility allows the PE pipe to be coiled, making trench-less installations safer. We supply long lengths of HDPE pipe, which eliminates the use of large numbers of joints and fittings and improves cost-effectiveness.


HDPE pipes can usually be joined by butt welding or electrofusion welding. The strength of the joint is higher than the pipe body and has the ability to resist water hammer pressure, resulting in greatly improved safety and reliability of the water supply.


HDPE pipe is resistant to a wide range of chemicals since the chemicals in the soil do not lead to the degradation of HDPE pipe. Moreover, polyethylene is an electrical insulator, so it will resist rotting and rusting or promoting the growth of algae and bacteria.

HDPE pressure piping systems adopt butt fusion welding for large-size connections. Small size connections are made by socket fusion welding.

Butt fusion welding uses a welder to heat the ends of the pipe (at a temperature of 210±10°C) until the ends are melted. Meanwhile the HDPE pipe ends should be quickly bonded and pressure maintained. All procedures are completed after cooling. The welding procedure can be found in the table below.

Product Knowledge

How does the flexibility of HDPE Pipe For Water affect its performance in water distribution systems?
The flexibility of HDPE Water Pipe plays a crucial role in their performance in water distribution systems. Here are several ways in which the flexibility of HDPE contributes to its effectiveness:
Ease of Installation:
HDPE pipes are known for their flexibility, allowing for easier handling during transportation, storage, and installation.
The material's flexibility simplifies the process of maneuvering around obstacles and adapting to the contours of the terrain.
Reduced Need for Joints:
The flexibility of HDPE allows for longer continuous lengths of pipe to be used without the need for frequent joints.
Fewer joints reduce the potential points of failure and leakage in the water distribution system.
Resistance to Ground Movement:
Water Supply HDPE Pipe can absorb and distribute stress caused by ground movement, such as settlement or minor earthquakes.
The flexibility helps prevent damage or failure due to shifts in the ground.
Trenchless Installation:
HDPE's flexibility makes it suitable for trenchless installation methods like horizontal directional drilling (HDD) and pipe bursting.
Trenchless methods minimize disruption to the environment and existing infrastructure while allowing for efficient installation.
Adaptability to Changing Conditions:
The flexibility of HDPE Pipe for Water Supply allows them to adapt to changes in temperature and external conditions.
HDPE can expand and contract with temperature variations without compromising its structural integrity.
Reduced Transportation Costs:
HDPE's flexibility enables the coiling of pipes for transportation, reducing shipping costs and the need for large transportation equipment.
Coiled pipes are easier to transport to the installation site.
Impact Resistance:
The flexibility of HDPE contributes to its impact resistance.
HDPE pipes can withstand impacts and external forces during installation or in service without cracking or breaking.
Improved Performance in Cold Weather:
HDPE maintains its flexibility even in cold weather conditions.
This characteristic is important for water distribution systems in regions with winter temperatures, as the pipes remain pliable and resistant to brittleness.
Minimized Risk of Water Hammer:
The inherent flexibility of HDPE helps absorb and dampen the effects of water hammer, reducing the risk of sudden pressure surges.
This is beneficial for protecting the integrity of the pipes and associated fittings.
Ductility and Resistance to Brittle Fracture:
The flexibility of HDPE is associated with its ductile nature, which means it can deform without undergoing brittle fracture.
This property contributes to the overall toughness and resilience of HDPE pipes.
Performance in Seismic Zones:
In seismic-prone areas, the flexibility of HDPE pipes allows them to absorb ground movement and seismic forces.
HDPE's ability to deform and return to its original shape helps prevent damage during earthquakes.
The flexibility of Black HDPE Water Pipe is a key attribute that enhances their performance in water distribution systems. It simplifies installation, reduces the risk of failures, and allows for adaptability to various conditions and installation methods. When properly designed and installed, flexible HDPE pipes contribute to the overall reliability and longevity of water distribution networks.
