Internal Epoxy & External 3PE Coated Steel Pipe

The pipe features an internal Fusion Bonded Epoxy (FBE) coating and a three-layer external 3PE coating system. The external coating consists of an epoxy powder primer, a graft-modified polyethylene adhesive layer and a polyethylene outer layer, providing strong adhesion, excellent corrosion resistance and reliable mechanical protection for long-term pipeline service.

Product Highlights

Three-Layer External Protection

The 3PE system combines an epoxy powder primer, adhesive layer and polyethylene outer layer for comprehensive external protection.

Strong Coating Adhesion

The epoxy primer provides strong adhesion to the prepared steel surface, while the adhesive layer ensures reliable bonding between the coating layers.

Excellent Corrosion Resistance

The multi-layer coating system provides effective protection against moisture, soil and other corrosive environments.

Enhanced Mechanical Protection

The polyethylene outer layer provides resistance to impact, abrasion and mechanical damage during handling, transportation and installation.

Smooth Internal Surface

The internal FBE coating provides a smooth flow surface and helps reduce internal corrosion and deposit buildup.

Long-Term Pipeline Protection

The integrated internal and external coating system is designed to provide reliable corrosion protection throughout the pipeline service life.
