Key Components
Pipe Transportation System: Ensures smooth and stable movement of the pipes throughout the entire coating process.
Shot Blasting Machine: Removes rust, oxide scale, and welding slag from the pipe surface to improve coating adhesion and surface roughness.
Intermediate Frequency Heating System: Maintains optimal pipe temperature to ensure proper fusion and curing of each coating layer.
3PE Coating System: Precisely applies the three coating layers: Fusion Bonded Epoxy (FBE), adhesive, and polyethylene (PE), ensuring strong bonding and consistent coverage.
Spray Cooling System: Rapidly cools and solidifies the coating layer, improving adherence and surface finish.
Coating Structure - 3-Layer PE:
Fusion Bonded Epoxy (FBE) Layer: Forms a high-strength, cross-linked molecular structure after curing, providing excellent chemical resistance and strong adhesion.
Adhesive Layer: Acts as a bonding bridge between the epoxy layer and polyethylene outer layer, ensuring cohesive strength across all three layers.
Polyethylene (PE) Outer Layer: Serves as the main protective barrier in underground or exposed pipeline environments, offering excellent resistance to abrasion, mechanical impact, and moisture.
Applicable Pipes: Hot bend pipes with diameters of 426 mm, 630 mm, 720 mm, and 820 mm.
Bending Radii: Supports bending radii of 4D to 6D.
Bending Angles: Between 15 and 90 degrees.
Pipe Wall Thickness: Ranges from 8 mm to 12 mm.
Coating Thickness: Meets international anti-corrosion standards:
Epoxy powder layer ≥170 μm
Adhesive layer 170-250 μm
Polyethylene outer layer 2.5-3.7 mm
General Equipment Dimensions: Approximately 20 meters by 15 meters.
Water Consumption: Around 30 cubic meters per cycle.
Total Power Consumption: 450 kilowatts, with gas usage of about 6 cubic meters per minute.
Recommended Operating Temperature: Inside the workshop should be no less than 5°C.
Oil and Gas Pipelines: Enhances corrosion resistance and ensures the safe transportation of fuels over long distances.
Municipal Water Supply Systems: Prevents internal contamination and ensures clean, long-lasting water delivery.
Industrial Fluid Transport: Ideal for transporting chemicals and other industrial fluids with high reliability.
