Custom-sized large-diameter PE solid-wall pipes for water supply and drainage, made from virgin material.

PE water supply and drainage pipes, namely polyethylene water supply and drainage pipes, are plastic pipes made primarily from high-density polyethylene (HDPE) through specific processes. The following is a detailed introduction to PE water supply and drainage pipes:
I. Main Features
Corrosion Resistance: PE water supply and drainage pipes have excellent corrosion resistance, can withstand erosion from various chemical media, and are free from electrochemical corrosion, ensuring the safety of water supply and drainage.
Flexibility: PE water supply and drainage pipes are highly flexible, easy to bend, and unaffected by uneven ground settlement. In engineering, the direction of the pipeline can be altered to bypass obstacles, or it can be directly laid in slightly uneven trenches without the need for pipe fittings.
Low-Temperature Resistance: PE water supply and drainage pipes have good low-temperature resistance, with an impact brittleness temperature of -70°C. No special protective measures are required during construction under general low-temperature conditions (0°C).
Abrasion Resistance: The abrasion resistance of PE water supply and drainage pipes is superior to that of ordinary steel pipes, being more than 4 times that of steel pipes. They can withstand the wear and tear of transporting abrasive media such as ore sand and slurry.
Hygienic Performance: During processing, PE water supply and drainage pipes do not require the addition of heavy metal salt stabilizers. The material is non-toxic, does not scale, and does not breed bacteria, avoiding secondary contamination of drinking water.
Long Service Life: Under rated temperature and pressure conditions, PE water supply and drainage pipes can be safely used for over 50 years.
Ease of Construction: PE water supply and drainage pipes are lightweight, making transportation and installation convenient, thereby reducing engineering installation costs. Additionally, the welding process is simple, construction is fast, and maintenance is straightforward.
II. Application Areas
Urban Water Supply Systems: With their excellent corrosion resistance, aging resistance, and good hygienic performance, PE water supply and drainage pipes are the material of choice for urban water supply systems. Whether for new urban water supply systems or the renovation and upgrading of old pipe networks, PE water supply and drainage pipes demonstrate high applicability and reliability.
Rural Drinking Water Safety Projects: PE water supply and drainage pipes play a crucial role in rural drinking water safety projects, effectively addressing issues such as rusting, cracking, and bacterial growth in traditional water pipes, ensuring the safety of drinking water for rural residents.
Agricultural Irrigation Systems: PE water supply and drainage pipes can be used in farmland irrigation systems to transport water sources to various agricultural areas, enabling efficient and water-saving irrigation. Their good pressure resistance and abrasion resistance allow them to withstand various pressures and impacts during irrigation.
Industrial Water Systems: PE water supply and drainage pipes are also widely used in industrial fields, such as water systems in chemical, petroleum, and power industries, as well as production water in food processing and pharmaceutical industries. Their excellent corrosion resistance and aging resistance ensure long-term stable operation of the pipelines.
Other Areas: PE water supply and drainage pipes can also be used for green irrigation and fountain landscapes in garden landscaping projects; in firefighting systems, they can be used to transport firefighting water; in seawater desalination projects, they can be used to transport seawater and desalinated water.
III. Implementation Standards
PE water supply and drainage pipes comply with the national product standards GB/T 13663.1-2017 and GB/T 13663.2-2018 "Polyethylene (PE) Piping Systems for Water Supply—Part 2: Pipes." These standards ensure that the quality and performance of PE water supply and drainage pipes meet relevant requirements.
In summary, with their unique properties and advantages, PE water supply and drainage pipes play a vital role in water supply and drainage systems. Whether in urban water supply, rural drinking water safety, agricultural irrigation, or industrial water use, PE water supply and drainage pipes demonstrate their irreplaceable status and value.
