Automatic 3LPE / 3LPP / FBE Steel Pipe Anti-Corrosion Coating Line for Oil & Gas

Product Description

The automatic steel pipe anti-corrosion coating production line is specially designed for applying high-performance anti-corrosion coatings to steel pipes of different diameters. It is widely used in oil, gas, district heating, water transmission, and other pipeline engineering industries.

The production line is suitable for:

FBE coating
Double-layer FBE coating
2PE / 2PP coating
3LPE coating
3LPP coating

The 3-layer PE anti-corrosion structure consists of:

1. Fusion Bonded Epoxy (FBE) primer layer
2. Copolymer adhesive middle layer
3. Polyethylene (PE) outer layer

The complete line integrates shot blasting, dust removal, induction heating, epoxy powder spraying, PE/PP extrusion coating, cooling, conveying, beveling, and automatic control into a fully automatic production system.
