HUASHIDA 3LPE Coating Pipe Production Line for 200mm-1420mm Steel Pipes with Epoxy+Adhesive+PE for Oil and Gas Pipelines
HUASHIDA 3 Layer PE 3LPE FBE Steel Pipe Anti-Corrosion Coating Machinery
3LPE Anti-Corrosion Coating Line
The outer anti-corrosion layer of 3PE steel pipe is a anti-corrosion structure composed of a bottom layer of epoxy powder, an intermediate layer of adhesive, and an outer layer of polyethylene composite. It has the characteristics of high mechanical strength and excellent electrical insulation performance.
200mm-1420mm anti-corrosion coating production line is used for anti-corrosion coating steel pipe with a larger diameter, which is more 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.
