Oil Gas Pipline Steel Pipe 3lpe 2lpe Fbe External Internal Coating Machine
Description
Steel pipe anti-corrosion coating production line is used for anti-corrosion coating steel pipe with diameter from 57mm to 1220mm, which are widely used in varieties of engineering construction, especially in the heating, gas, oil industry.
This line 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, a middle adhesive layer, and an outer polyethylene layer.
The three-layer polyethylene anti-corrosion coating is an 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 pipelines. 3 layer PE anti-corrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable, and anti-aging performance.
