3PE anti-corrosion seamless steel pipe is a steel pipe anti-corrosion process, and its base material is seamless steel pipe.
The 3PE anti-corrosion coating, also known as three-layer polyethylene coating, is a modern protective system that merges the advantages of European 2PE coatings with fusion bonded epoxy (FBE) technology. This innovative combination has been widely recognized and adopted both domestically and internationally for its outstanding durability and performance.
By integrating the strong adhesion and chemical resistance of epoxy resin with the excellent impermeability and mechanical strength of polyethylene, the 3PE coating offers superior corrosion protection. It is globally regarded as one of the most effective pipeline coatings and is extensively applied in various infrastructure projects, including long-distance water transmission, oil and gas transportation, chemical pipelines, district heating networks, sewage systems, offshore structures, bridge supports, and foundation piling.
When applied to seamless steel pipes, the 3PE coating enhances their reliability and extends their service life in harsh environments. Here are details of 3PE seamless steel pipe, read on to learn more.

The 3PE (Three-Layer Polyethylene) coated steel pipe features a robust three-layer protective system:
Epoxy Primer Layer
The innermost layer consists of fusion bonded epoxy (FBE) powder, typically over 100μm thick. Applied directly to the pipe surface, it provides excellent adhesion and resistance to high temperatures, ensuring a strong bond for the subsequent layers.
Copolymer Adhesive Layer
Made primarily of polyolefin, this middle layer has a thickness ranging from 170μm to 250μm. It serves as a bonding agent between the epoxy primer and the outer polyethylene layer, ensuring cohesive adhesion and added corrosion resistance.
Polyethylene (PE) Outer Layer
The outermost layer is extruded polyethylene, with a thickness of 2.5 mm to 3.7 mm. This layer offers superior protection against water, chemicals, electrical conductivity, and mechanical damage, making it a critical barrier for long-term pipe performance in harsh environments.
