Epoxy coal‑tar pitch anti‑corrosion steel pipe is one of the most common external anti‑corrosion pipelines for buried‑laid steel pipes. It takes spiral‑welded, straight‑seam or seamless steel pipe as the base material, and coats the outer wall with epoxy coal‑tar pitch paint. Glass‑fiber cloth can be wrapped for reinforcement to form anti‑corrosion structures of two‑cloth three‑oil, three‑cloth four‑oil, four‑cloth five‑oil and so on.

The anti‑corrosion coating has strong waterproof performance, good adhesion, excellent resistance against acid, alkali, salt water and microbial corrosion. It can provide long‑term reliable protection for steel pipes buried in wet soil, swamp, saline‑alkali land and other harsh environments.

Different anti‑corrosion grades can be customized according to local geological conditions. Every pipe will pass appearance inspection and coating thickness test before delivery.

It is widely used in sewage drainage, industrial waste‑water conveyance, municipal underground drainage pipelines, oil‑water transmission, port and wharf foundation anti‑corrosion projects.
