TPEP anti-corrosion steel pipe is a professional double-sided composite anti-corrosion pipeline specially optimized for water transmission and water conservancy projects. Adopting outer 3PE polyethylene anti-corrosion and inner FBE fusion-bonded epoxy coating, it solves the common problems of traditional pipelines such as easy rusting, scaling, water pollution and short service life.

The outer three-layer polyethylene (3PE) structure provides excellent waterproof, anti-corrosion and mechanical protection. It effectively resists soil corrosion, groundwater immersion and external mechanical damage during long-term buried laying, ensuring stable external protection in complex geological environments.

The inner epoxy powder coating forms a dense, smooth, non-toxic and hygienic protective layer. The uniform and pinhole-free inner wall avoids secondary water pollution, reduces water flow friction, improves water delivery efficiency, and effectively prevents scaling and microbial growth inside the pipeline.

All water delivery TPEP steel pipes are manufactured strictly according to GB/T 23257-2017 and GB/T 28708-2012 national standards. Standard-grade and reinforced-grade anti-corrosion treatments are optional to adapt to urban water supply, long-distance water diversion, reservoir water delivery and sewage conveyance environments. Every finished pipe passes spark leakage detection, coating thickness test and adhesion test before delivery.

With ultra-long service life, safe water quality and low maintenance cost, TPEP anti-corrosion steel pipe has become the most ideal pipe material for municipal water supply, cross-region water transfer, farmland irrigation and large water conservancy pipeline projects.
