3LPE Coating Pipe Production Line and 3LPE Coating Line with 50-4200mm Pipe Diameter Internal and External Coating Induction Heating

The steel pipe anti-corrosion coating line is designed for factory-applied anti-corrosion coating of steel pipes in various diameters. It is widely used in engineering construction, particularly in heating, gas, and oil field applications.

The line supports multiple coating technologies, including FBE, 2-layer FBE, 2-layer PE, 2-layer PP, and 3-layer PE anti-corrosion coating. The 3-layer PE anti-corrosion coating consists of a first FBE coating, a middle adhesive layer, and an outer polyethylene layer.

The three-layer polyethylene (3LPE) anti-corrosion coating is an advanced technology used as the outer protective layer for buried pipes. It is widely applied in the anti-corrosion protection of gas and oil transmission pipelines, urban gas supply networks, water supply pipes, and other fluid transmission pipelines.

The 3-layer PE anti-corrosion coating strengthens the pipeline's mechanical properties with high electrical resistance, waterproofing, wear resistance, and anti-aging performance.

The anti-corrosion coating processing line includes the following systems:

• Steel pipe transmission system
• Surface treatment system
• Pipe dust removal system
• Pipe heating system
• Electrostatic spraying system
• Coating system
• Water cooling system
• End cutting system
• Hydraulic and pneumatic system
• Testing system
• Electronic control system
