3PE anti‑corrosion spiral‑welded steel pipe is specially used for buried natural‑gas transmission pipelines. Adopting spiral‑welded steel pipe as base material, it is coated with three‑layer polyethylene anti‑corrosion coating. With excellent corrosion resistance, low water‑vapor permeability and stable mechanical property, it effectively protects the pipe from underground moisture and soil corrosion, extending the service life of gas pipelines.

We can supply both standard‑grade and reinforced‑grade 3PE coating. Produced in compliance with GB/T 23257‑2017, our factory holds ISO system certifications. All pipes are strictly inspected before delivery. Mill test certificates are available for overseas gas‑supply projects. Suitable for urban gas‑network, long‑distance natural‑gas trunk‑lines and gas‑field gathering pipelines.
