Epoxy coal‑tar pitch anti‑corrosion steel pipe is an economical and reliable outer‑wall anti‑corrosion solution for buried steel pipelines. Based on spiral‑welded, straight‑seam or seamless steel pipe, its anti‑corrosion layer is formed by brushing epoxy coal‑tar pitch paint, with fiberglass cloth added for reinforcement upon request.

Various layered structures are available: two‑cloth three‑oil, three‑cloth four‑oil, four‑cloth five‑oil and other reinforced grades. The composite coating creates a thick, impermeable barrier over the steel surface, delivering outstanding waterproof, anti‑acid, anti‑alkali and anti‑microbial performance.

It adapts perfectly to harsh underground environments such as saline‑alkali soil, wetland and river‑side foundation. Custom‑made anti‑corrosion schemes are offered to match different soil corrosion levels. Strict inspections for coating thickness, surface quality and adhesion are carried out before delivery.

This cost‑effective anti‑corrosion pipe is widely selected for sewage drainage, underground municipal sewer lines, industrial waste‑water transport, wharf foundation protection and other non‑potable‑water buried pipeline works.
