TPEP anti‑corrosion steel pipe for tap‑water is a hygienic double‑sided composite anti‑corrosion pipeline specially designed for urban and rural municipal water‑supply networks. It adopts outer three‑layer polyethylene (3PE) anti‑corrosion coating and inner food‑grade fusion‑bonded epoxy powder coating.

The outer 3PE protective layer possesses outstanding waterproof, impact‑resistant and anti‑aging performance. It can effectively isolate the steel substrate from humid soil, underground water and corrosive substances, delivering long‑term stable protection for buried pipelines.

The inner epoxy coating is safe and non‑toxic, satisfying tap‑water sanitary requirements. The smooth inner wall reduces water‑flow resistance, improves water‑supply efficiency, prevents scaling and bacterial reproduction, and avoids secondary pollution to tap‑water.

Manufactured strictly in accordance with GB/T 23257‑2017 and GB/T 28708‑2012 standards. Standard‑grade and reinforced‑grade anti‑corrosion can be customized for different geological environments. Every pipe passes spark‑leakage inspection, coating‑thickness test and adhesion test before shipment.

It is widely applied in municipal tap‑water network reconstruction, urban water‑supply projects, community water‑supply, rural tap‑water projects and long‑distance drinking‑water diversion.
