◉ Corrosion Resistance: Polyethylene is an inert material that can withstand corrosion from various chemical media, No electrochemical corrosion, no need for anti-corrosion protective layer.
◉High Tenacity: PE water supply pipe is a high-tenacity pipe with a general elongation at break exceeding 500%. It has strong adaptability to uneven settlement of the pipe foundation and is a pipe with excellent seismic performance.
◉ Safe and Non-toxic: PE pipes are light in weight, with simple welding technology, convenient construction, and low overall project cost.
◉ Simple Construction: PE water supply pipes contain no heavy metal additives, do not incrustate, and do not breed bacteria.
◉ Good Sealed: PE water supply pipes mainly adopt fusion connection (hot-melt connection or electro-fusion connection) and socket connection. Compared with rubber joint or other mechanical joints, there is no risk of leakage caused by joint distortion.
◉ Long Service Life
The PE water supply pipes produced by our company are divided into two series based on the raw materials used: PE80 and PE100. The PE100 series can be divided into SDR11, SDR13.6, SDR17, SDR21
SDR26 has five levels; The PE80 series is divided into five levels: SDR11, SDR13.6, SDR17, SDR21, and SDR33.
