Steel Pipe FBE 3LPE Anti-Corrosion Coating Line for Long Distance Oil gas Pipelines

This Steel Pipe FBE 3LPE Anti-Corrosion Coating Line is a fully automatic, high-throughput external anti-corrosion coating production line purpose-engineered for factory-grade external surface treatment of steel pipes across an ultra-wide diameter range of 36mm to 4200mm - the broadest diameter coverage available for long distance oil & gas pipeline external coating in this product category.

Configured exclusively for external shot blasting and 3LPE coating, this line delivers the right-sized solution for long distance oil & gas pipeline projects specifying external-only corrosion protection without the capital cost of internal coating capability.

• Layer 1 - FBE Epoxy Base Layer: Fusion Bonded Epoxy powder forms a high-molecular cross-linked dense protective structure with outstanding chemical anti-corrosion performance, wear resistance, and mechanical strength
• Layer 2 - Polymer Adhesive Middle Layer: Hot melt adhesive layer forms the structural bridge between FBE base and PE outer skin, ensuring long-term delamination resistance
• Layer 3 - High-Density Polyethylene Outer Protective Layer: Provides mechanical impact resistance, abrasion protection, and waterproof barrier against soil stress and groundwater

• Ultra-Wide 36-4200mm Diameter Coverage: Processes full spectrum from small-bore gathering lines to large-diameter transmission pipelines
• External-Only Pipeline Configuration: Purpose-built for external shot blasting and 3LPE anti-corrosion coating
• Sa2.5 Shot Blasting Surface Preparation: Achieves international surface cleanliness standard before coating application
• Low Friction External 3LPE Coating Surface: Reduces soil friction during installation and fluid transmission resistance
• ≤250m²/h High-Throughput Performance: Full PLC automatic control sustains high processing capacity
• Zero-Emission Environmental Compliance: Professional dust collector and powder recovery system compliant with CE and ISO14001 standards

• Process Adaptability: Supports single-layer FBE, 2LPE, 2LPP, and 3LPE external coating configurations
• Energy-Efficient Performance: Precise intermediate frequency heating system with ±2°C temperature accuracy
• Processing Capacity: ≤250m²/h sustained processing capacity across full diameter range
• Environmental Compliance: CE & ISO14001 environmental standards compliance
• International Standards: Meets DIN 30670, BS EN 10329, AWWA C215, and DNV requirements
