3PE Steel Pipe Outer Wall External Anticorrosion Coating Machine
Description
Steel pipe anti-corrosion coating production line is used for anti-corrosion coating steel pipe with a diameter from 32mm to 1220mm, which is widely used in varieties of engineering construction, especially in the heating, gas, oil field.
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, middle adhesive layer and outer polyethylene layer.
The three-layer polyethylene anti-corrosion 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 pipelines. 3 layer PE anti corrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable and anti-aging performance.
