Steel pipe with inner‑wall IPN8710 anti‑corrosion coating forms a protective lining by brushing non‑toxic IPN8710 interpenetrating polymer network paint on the inner wall of the base steel pipe.

Only the inside of the pipe is treated with anti‑corrosion coating. The lining meets drinking‑water sanitary requirements, produces no secondary pollution to water quality, and offers great resistance to acid, alkali, salt and water‑borne corrosion. Spiral‑welded, straight‑seam and seamless steel pipes are all optional base materials. Custom sizes are supported.

It is mainly used in municipal tap‑water supply, drinking‑water transmission, water‑plant pipelines, industrial circulating‑water and sewage‑transport projects.
