The coating surface of water‑supply plastic‑coated steel pipe is smooth and attractive, with optional outer‑layer colors. Its smooth inner wall inhibits microorganism growth, reduces fluid transmission resistance, increases flow capacity and saves energy. It is widely applied in various water supply and drainage projects.

It is mainly used for drinking‑water delivery pipelines, as well as for seawater, reclaimed water, chemical, petroleum media and most acid, alkali and salt solutions. It is especially suitable for buried pipelines with long service life.
