3PE anti‑corrosion steel pipe can take seamless steel pipe, spiral‑welded steel pipe and straight‑seam steel pipe as base materials. A full range of small‑to‑large diameters are available.

The three‑layer polyethylene (3PE) anti‑corrosion coating is composed of fusion‑bonded epoxy primer, adhesive layer and high‑density polyethylene outer layer. With excellent corrosion resistance, low water‑vapor permeability and stable mechanical properties, 3PE‑coated pipes are widely used in petroleum, natural gas, municipal water supply and buried pipeline engineering.

The outer anti‑corrosion coating plays a decisive role in the service life of buried pipelines. For steel pipes with identical base material, pipes with high‑quality 3PE anti‑corrosion layer can work underground for decades without corrosion, while pipelines with poor anti‑corrosion treatment may suffer leakage within only a few years.

We can supply both standard‑grade and reinforced‑grade 3PE coatings according to different soil and geological conditions. All products are produced strictly in accordance with GB/T 23257‑2017. Every pipe will pass complete inspections before delivery, and mill‑test certificates can be provided for overseas projects. It is an ideal choice for long‑distance oil‑gas transmission, urban water supply, sewage discharge and other buried industrial pipeline projects.
