Add to Cart
Steel pipe anti-corrosion 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, oil field.
The lines can be utilized for FBE, 2-layer FBE, 2-layer PE, 2-layer PP, and 3-layer PE corrosion-resistant coatings.
3 layer PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.
Steel Bend pipe FBE &3LPE coating Production Line
The three-layer polyethylene Anticorrosion coating is advanced technology as the outer protective layer of buried pipe, widely used in the anti-corrosion of gas and oil transmission pipeline, urban gas supply, water supply pipe and other fluid transmission pipeline. 3 layer PE Anticorrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable and anti-aging performance.
