BV Audited 3LPE FBE Steel Pipe Coating Line for Water Gas Pipelines
Full Automatic 3LPE FBE Steel Pipe Anti-Corrosion Coating Line with Shot Blasting
Internal & External FBE Powder Coating
The BV Audited 3LPE FBE steel pipe coating line is a fully automatic, turnkey pipe coating production system engineered for factory-applied internal FBE and external 3LPE anti-corrosion treatment of large-diameter steel pipes for water gas pipelines, oil and gas transmission, district heating pipe fabrication, municipal water supply networks, and buried pipeline infrastructure. As a Bureau Veritas (BV) audited supplier (ID: MIC-ASR2551964) - the strictest international third-party factory verification standard - this line combines independently verified manufacturing quality with the broadest multi-standard coating compliance available: ISO 21809-1, DIN 30670, DNV, and SY/T0413 simultaneously.
Designed for oil and gas pipeline manufacturers, oilfield service companies, municipal water gas pipeline fabricators, district heating pipe producers, and buried pipeline EPC contractors, this BV Audited FBE 3LPE steel pipe anti-corrosion coating line supports multiple coating configurations - single-layer FBE, 2LPE, 2LPP, and full 3LPE composite anti-corrosion coating - from one flexible production platform. The line is actively deployed across the Middle East, Central Asia, Russia, Africa, and Southeast Asia water gas pipeline markets.
This complete turnkey 3LPE FBE coating production line integrates internal and external shot blasting derusting (Sa2.5), medium-frequency induction heating (±2°C accuracy), electrostatic FBE epoxy powder spraying, hot melt adhesive extrusion, outer three-layer polyethylene (3LPE) cladding, water spray cooling, pipe end beveling, and centralized PLC automatic control into a single continuous workflow - achieving one-step synchronous forming of the internal Fusion Bonded Epoxy (FBE) primer layer, intermediate adhesive layer, and outer 3LPE polyethylene protective layer at 0-6m/min adjustable line speed delivering 250m²/h processing capacity for water gas pipeline anti-corrosion coating manufacturing.
Coating Principle
Fusion Bonded Epoxy (FBE) powder is a non-toxic, thermosetting anti-corrosion coating 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 and water gas pipeline anti-corrosion systems complying with ISO 21809-1, DIN 30670, and DNV international standards.
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 this BV Audited industrial-grade water gas pipeline coating equipment.

Process Adaptability
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 BV Audited coating line ideal for municipal water gas supply pipe, long-distance oil gas transmission pipe, district heating pipeline, and diversified industrial buried water gas pipeline coating engineering requirements across Middle East, Central Asia, Russian, African, and Southeast Asian markets.
Efficient and Stable High-Speed Performance
Precision medium-frequency induction heating maintains ± 2°C temperature accuracy, ensuring uniform FBE epoxy powder melting and consistent 3LPE coating adhesion batch after batch for water gas pipeline production. Adjustable spiral pipe conveyor speed accommodates variable large-diameter steel pipe from 325-4200mm, delivering stable 250m²/h throughput and repeatable 3LPE FBE anti-corrosion coating quality at 0-6m/min line speed across every water gas pipeline production run.
Environmental Compliance
