The 3PE (Three-Layer Polyethylene) anti-corrosion coating line is designed for the external coating of steel pipes used in oil, gas, water supply, district heating, and industrial pipeline systems.
The 3PE coating structure consists of three functional layers:
1. FBE Layer (Fusion Bonded Epoxy)
Provides excellent adhesion to the steel pipe surface and strong corrosion resistance.
2. Adhesive Layer (AD)
Ensures reliable bonding between the epoxy coating and the polyethylene outer layer.
3. Polyethylene Layer (PE)
Provides mechanical protection, low water absorption, and strong environmental resistance.
This multi-layer coating system offers excellent anti-corrosion performance, high mechanical strength, electrical insulation, and long service life, making it an ideal solution for modern pipeline protection.
Pipe Loading → Conveying → Shot Blasting → Induction Heating → FBE Coating → AD & PE Extrusion Coating → Water Cooling → Conveying → Pipe End Grinding → Pipe Unloading
Includes shot blasting machine, cyclone dust collector, pulse dust collector, and exhaust fan for effective rust removal and surface cleaning.
Equipped with induction heating equipment to ensure stable and uniform pipe surface temperature before coating.
Includes epoxy powder spraying unit, adhesive extruder, PE extruder, die heads, and coating pressing device for complete 2LPE / 3LPE coating application.
Water spray cooling system ensures stable cooling performance and coating quality.
Includes pipe loading platform, conveying system, unloading platform, and turning devices for smooth production flow.
PLC automatic control system for stable, efficient, and intelligent operation.
Includes PE grooving / beveling machine, hydraulic lifting system, and ventilation equipment.
Provides long-term corrosion protection for steel pipes in harsh environments.
The coated pipe system can achieve a service life of 30–50 years.
Maintains good toughness and impact resistance, even in low-temperature conditions.
High sealing performance and efficient production help reduce maintenance and operation costs.
Advanced PLC control system ensures easy operation, stable performance, and improved production efficiency.
