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 pipeline. 3 layer PE anti-corrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable and anti-aging performance.
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.
