Automatic 3LPE Coating Pipe Production Line with PLC Control System and FBE Epoxy Powder Coating

HUASHIDA Oil & Gas Pipe 3LPE Anti-Corrosion Coating Line is designed for applying anti-corrosion coatings on steel pipes. It is widely used in various engineering construction projects, especially in the fields of oil, gas, heating, and water pipeline systems.

This production line is capable of applying different types of coatings, including:

• Fusion Bonded Epoxy (FBE)
• 2-Layer FBE
• 2-Layer PE
• 2-Layer PP
• 3-Layer PE (3LPE) Anti-Corrosion Coating

The 3-layer PE coating consists of an inner Fusion Bonded Epoxy (FBE) layer, a middle adhesive layer, and an outer polyethylene layer. This advanced coating technology offers excellent anti-corrosion performance and mechanical strength, significantly extending the service life of pipelines. It features high electrical resistance, superior waterproof properties, wear resistance, and excellent anti-aging performance, making it suitable for various buried pipelines.
