HUASHIDA Steel pipe anticorrosion coating line is used for anti-corrosion coating steel pipe in the factory with various diameter, which is more widely used in varieties of engineering construction, especially in the heating, gas, water supply pipe and other fluid transmission pipeline.
3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.
Coating Structure
The 3LPE system provides comprehensive pipeline protection through three integrated layers:
1.Fusion-Bonded Epoxy (FBE) Powder Layer
Chemically bonds to steel substrate for superior adhesion and cathodic disbondment resistance
2.Co-Polymer Adhesive Layer
Ensures permanent bonding between epoxy and polyethylene layers
3.High-Density Polyethylene (HDPE) Layer
Provides mechanical protection against impact, abrasion, and environmental stress
Production line Process:
Upload pipe → Pipe screw conveyor → Internal rust removal → External rust removal → Medium frequency heating → Internal epoxy powder coating → External epoxy powder coating → Outer layer bonding polyethylene coating → Cooling spraying → Pipe screw conveyor → Pipe end face grinding → Unloading pipe.
