Audited Supplier PE Extrusion Three Layer Steel Pipe External Corrosion Protective 3LPE Coating Machine 
Description
Automatic 3LPE steel pipe external corrosion protective coating machine is used for anti-corrosion coating steel pipes, 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.
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.
