HDPE Water Supply Pipes
HDPE water supply pipes are manufactured in a single extrusion process using specialized polyethylene as the raw material. They are widely used in urban water distribution networks, irrigation and water‑intake projects, and agricultural sprinkler‑irrigation systems. These pipes are particularly well suited to environments that demand resistance to acids, alkalis, and corrosion. Thanks to their fusion‑welded or electrofusion joints, HDPE pipes achieve seamless integration between the pipe body and its fittings, effectively withstanding both circumferential stresses caused by internal pressure and axial impact loads. Moreover, HDPE is non‑toxic, does not scale, and inhibits bacterial growth, thereby preventing secondary contamination of drinking water.

Product Introduction
HDPE water supply pipes are manufactured in a single extrusion process using specialized polyethylene as the raw material. They are widely used in urban water distribution networks, irrigation and water‑intake projects, and agricultural sprinkler‑irrigation systems. These pipes are particularly well suited to environments that demand resistance to acids, alkalis, and corrosion. Thanks to their fusion‑welded or electrofusion joints, HDPE pipes achieve seamless integration between the pipe body and its fittings, effectively withstanding both circumferential stresses caused by internal pressure and axial impact loads. Moreover, HDPE is non‑toxic, does not scale, and inhibits bacterial growth, thereby preventing secondary contamination of drinking water.
One-stop supply of large-diameter PE pipes and fittings. With a commitment to pragmatism and innovation, Luoyang Zhongxiong Pipe Industry Co., Ltd. manufactures HDPE pipes ranging from DN20 to DN1400. Our products have been supplied for numerous large-diameter solid-wall PE pipe projects both domestically and internationally, with applications spanning water supply and drainage, dredging, sand extraction, and more. Leveraging years of experience in PE pipe production, our company has successfully obtained multiple certification standards for PE pipes.
Implementation Standard
PE water supply pipe national standard GB/T 13663.2-2018; this standard, compared with the international standard… ISO 4427:1996 “Specification for Polyethylene Pipes for Water Supply” has only minor additions or deletions.
Application areas
- Urban municipal water supply network system
- Urban and Rural Drinking Water Supply
- Agricultural irrigation pipeline
- Electrical wire protection conduit
- Municipal industrial drainage and sewage pipelines
- Mine mortar conveying pipeline
- Landscape irrigation piping
- Dredging of sediment from ports, rivers, and lakes
- Transportation of Crude Oil Wastewater
- Material and liquid conveying pipelines for industries such as chemical engineering, synthetic fibers, food processing, forestry, textile printing and dyeing, pharmaceuticals, light industry, papermaking, and metallurgy.
Product Superiority
- Strong corrosion resistance: It is resistant to corrosion by a wide range of chemical media, and the chemicals present in soil do not cause any degradation of the pipeline.
- High wear resistance: Comparative wear‑resistance tests demonstrate that PE pipes exhibit four times the wear resistance of steel pipes. In slurry‑transport applications, they offer superior wear resistance, longer service life, and enhanced cost efficiency.
- Long aging resistance and service life: Polyethylene pipes containing 2–2.5% uniformly dispersed carbon black can be stored or used outdoors for 50 years without degradation due to ultraviolet radiation.
- Lightweight and easy to install: PE pipes are lighter than concrete, galvanized, and steel pipes. Their ease of handling and installation, combined with reduced labor and equipment requirements, significantly lowers project installation costs.
- Strong resistance to stress cracking: It exhibits low notch sensitivity, high shear strength, and excellent scratch resistance, with particularly outstanding resistance to environmental stress cracking.
- Low flow resistance: With a smooth inner surface and a Manning roughness coefficient of 0.009, its smoothness and non‑adhesive properties ensure that the pipeline delivers higher flow capacity than conventional pipe materials, while also reducing pressure losses and water‑transport energy consumption.
- Reliable connection: The pipeline system is joined using hot‑fusion socket and hot‑fusion butt fusion methods, with joint strength exceeding that of the pipe itself; polyethylene pipes are connected to other pipelines via flanged joints, ensuring convenience and speed.
- Strong low-temperature impact resistance: The low-temperature embrittlement temperature is extremely low, allowing for safe use across a temperature range of –60°C to 60°C. During winter installation, the material’s excellent impact resistance prevents pipe cracking.
