Polyethylene material was for the first time produced in the beginning of the 1930s, but production of pipes from polyethylene was begun in the middle of the 1940s. The first standard for polyethylene pipes was published in 1953 in England.

High-density polyethylene (HDPE) is a thermoplastic polymer produced from the monomer ethylene. It is sometimes called "alkathene" or "polythene" when used for HDPE pipes. Its high level of impermeability and strong molecular bond make it suitable for high pressure pipelines. 

HDPE pipe is used across the globe for applications such as water mains, gas mains, sewer mains, slurry transfer lines, rural irrigation, fire system supply lines, electrical and communications conduit, and stormwater and drainage pipes. The toughness and resistance to chemicals of polyethylene, as well as the corrosion resistance and low weight have contributed to its growing use in situations where cost-effective and durable fluid and gas piping systems are required. 

HDPE pipe can be joined by butt welding, electrofusion welding, socket welding, or extrusion welding. These joints heat the pipe during the joining process, creating a completely homogeneous joint so the weld becomes as strong, or stronger than the existing pipe on either side of the weld. 

As a leading HDPE pipe manufacturer, YAGENE have been working with top Chinese food-grade HDPE virgin granule suppliers for manufacturing safe and healthy pipelines since 2008. And we are proudly serving municipal water system, agricultural irrigation and fire-fighting water supply system with shorter lead time, high cost-efficiency, and exceptional performance.
