Product Description

Oil/gas pipeline 3LPE/2PE/PP pipe inner&outer anticorrosion coating machinery 

Steel pipe anti-corrosion coating production line is used for anti-corrosion coating steel pipe with diameter from 57mm to 1220mm, 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.

Production range: Pipe diameter 32mm-325mm
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.
