China Steel Pipe External 3PE Anti-Corrosion Coating Machine Line PE Extrusion Three Layer PE Coating Line

Steel Pipe External 3PE Anti-Corrosion Coating Machine/Line PE Extrusion Three Layer PE Coating line
Description
Steel pipe 3PE external 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.
3PE anti-corrosion coating consists of first FBE coating, middle adhesive layer and outer polyethylene layer.
The 3PE 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. 3PE anti-corrosion coating can strengthen the pipeline's mechanical properties with high electrical resistance, waterproof, wearable and anti-aging performance.
Steel pipe 3PE external anti-corrosion coating production line includes the following systems:
-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.
