3LPE FBE Steel Pipe Anti-Corrosion Coating Line with Shot Blasting for Water Gas

The Huashida FBE 3LPE steel pipe anti-corrosion coating line is a fully automatic, turnkey pipe coating production system engineered for factory-applied anti-corrosion treatment of large-diameter steel pipe. Designed for oil and gas pipeline manufacturers, oilfield service companies, district heating pipe fabricators, municipal water supply pipe producers, and buried pipeline infrastructure contractors, this steel pipe anti-corrosion equipment supports multiple coating configurations - single-layer FBE coating, 2LPE, 2LPP, and full 3LPE composite anti-corrosion coating - from one flexible production platform.

This complete turnkey 3LPE coating production line integrates internal and external shot blasting derusting, medium-frequency induction heating, electrostatic FBE epoxy powder spraying, hot melt adhesive extrusion, outer 3-layer polyethylene (PE) cladding, water spray cooling, pipe end beveling, and centralized PLC automatic control into a single continuous workflow. The system achieves one-step synchronous forming of the internal FBE epoxy primer layer, intermediate adhesive layer, and outer 3LPE polyethylene protective layer - fully complying with ISO 21809-1, DIN 30670, DNV, and SY/T0413 international pipeline anti-corrosion coating standards for long-service buried and offshore steel pipeline protection.

FBE (Fusion Bonded Epoxy) powder is a non-toxic, thermosetting anti-corrosion raw material. After precision high-temperature curing, it forms a dense, high-molecular crosslinked protective film delivering outstanding chemical corrosion resistance, abrasion resistance, anti-aging performance, and high mechanical strength. The FBE primer layer bonds tightly to the Sa2.5 blast-cleaned steel substrate, providing superior adhesion, acid-alkali tolerance, and excellent cathodic disbondment resistance - the core performance indicator for buried and offshore oil & gas pipeline anti-corrosion systems.

The intermediate polymer adhesive layer fuses seamlessly onto the uncured FBE epoxy surface, then bonds firmly with the outer polyethylene sheath, forming a robust three-layer composite anti-corrosion structure (3LPE) - the defining technical advantage of industrial-grade buried steel pipe coating equipment.

• Superior Anti-Corrosion Performance: Combined internal and external FBE 3LPE multilayer protection shields steel pipe from chemical erosion, aging, and mechanical impact, ensuring reliable long-term operation in harsh oilfield, underground, coastal, and offshore corrosive environments.
• Low Friction Internal Coating Surface: Smooth FBE internal lining reduces fluid transmission resistance, improving conveying efficiency and lowering long-term operational energy costs for oil, gas, and municipal water pipeline networks.
• Broad Engineering Compatibility: A preferred 3LPE anti-corrosion manufacturing solution for long-distance oil & gas transmission pipelines, urban gas distribution, municipal water-drainage systems, district heating networks, and large-scale buried infrastructure projects.
• High Automation & Optimized Cost of Ownership: Fully automatic continuous production workflow minimizes manual labor input, while stable, low-failure-rate operation delivers a favorable total cost of ownership for steel pipe anti-corrosion manufacturers worldwide.
• Global Standards Compliance: Certified to ISO 21809-1, DIN 30670, DNV, and SY/T0413, supporting EPC pipeline project bidding and regulatory approval across international markets.

Flexible, modular equipment design supports independent single-layer FBE spraying or full composite 3LPE anti-corrosion coating, including combined outer 3LPE + internal FBE (TPEP) dual-layer structures. This adaptability makes the line ideal for municipal water supply pipe, long-distance oil & gas transmission pipe, district heating pipeline, and diversified industrial pipe coating engineering requirements.

Precision medium-frequency induction heating maintains ± 2°C temperature accuracy, ensuring uniform epoxy powder melting and consistent coating adhesion batch after batch. Adjustable spiral pipe conveyor speed accommodates variable large-diameter steel pipe specifications, delivering stable throughput and repeatable anti-corrosion coating quality across every production run - supporting processing capacity up to 250 m²/h at line speeds of 0-6 m/min.

Equipped with an integrated cyclone and pulse dust collection system plus a closed-loop FBE powder recovery unit, the coating line fully satisfies CE and ISO 14001 environmental protection standards. Zero visible dust emission ensures compliance with global factory HSE requirements for steel pipe shot blasting and powder coating workshops.
