Polyethylene (PE) pipes for water supply

Huaxi Village’s polyethylene (PE) pipes are made from either imported or domestically produced high-density polyethylene resins specifically designed for pipeline applications. They are manufactured in accordance with the national standard GB/T13663.2-2018 and boast a range of superior features, including high strength, hygienic properties, non-toxicity, impact resistance, resistance to aging, corrosion resistance, light weight, and ease of installation. Widely used across multiple sectors, these pipes are an ideal replacement for conventional iron water pipes because they do not rust.

Product Details

hs Earthquake-resistant and weather-resistant

It has strong adaptability to uneven foundations and misalignments, and can withstand harsh environmental conditions such as earthquakes and typhoons.

hs Ultra-high strength

Always maintains high strength, excellent resistance to environmental stress cracking, and good creep resistance.

hs Corrosion-resistant

Corrosion-resistant, no need for anti-corrosion treatment, and long service life.

hs Environmentally friendly and non-toxic

Non-toxic, safe and hygienic, polyethylene itself is a non-toxic, recyclable material that does not pollute the environment.

hs Easy to install and maintain

Easy and reliable connection, simple construction and maintenance (without interrupting water supply during the process), suitable for both open-cut and trenchless technologies.

hs Resistant to low-temperature impact

It has excellent resistance to low-temperature impact and can be safely used within a temperature range of -20°C to 40°C, with no adverse effects on winter construction.
