A steel pipe anti - corrosion coating line is utilized in the factory to apply anti - corrosion coatings to steel pipes of various diameters. These coated pipes are more extensively employed in diverse engineering construction projects, particularly in heating, gas, and oil fields.

The lines can be applied to FBE, 2 layer FBE, 2 layer PE, 2 layer PP and 3 layer PE anti-corrosion coating.

3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.

(Dia. 500-4200mm)

Internal FBE external 3LPE coating line
(Dia. 159-4200mm)

Small size steel pipe O-type extrusion 3LPE coating line
(Dia. 57-426mm)

Steel Bend pipe FBE &3LPE coating Production Line

The three-layer polyethylene anti-corrosion coating represents a state-of-the-art technique for serving as the external protective layer of buried pipes. It finds extensive application in safeguarding gas and oil transmission pipelines, urban gas supply systems, water supply pipes, and other conduits for fluid transportation. This 3-layer PE anti-corrosion coating is capable of enhancing the pipeline's mechanical attributes while offering high electrical resistivity, water resistance, abrasion resistance, and anti-aging capabilities.

The anti-corrosion coating processing line includes:
-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.
