Three-Layer Polyethylene (3PE) Anti-Corrosion Coating System for Buried Steel Pipes
Three-Layer Polyethylene (3PE) Anti-Corrosion Coating System for Buried Steel Pipes
3PE is a new anti-corrosion coating for steel pipes, which ingeniously combines Europe's 2PE anti-corrosion coating with the fusion-bonded epoxy (FBE) coating widely adopted in North America.
3-layer PE anti-corrosion coating consists of three layers:
- FBE (Fusion bonded epoxy) coating, FBE>100um
- Adhesive layer, 170~250um
- Polyethylene layer, 1.8~3.7mm
The three layers are integrated and firmly combined with the steel pipe to form an excellent anti-corrosion coating.
