Certified 3LPE FBE Steel Pipe Anti-Corrosion Coating Line for Water Gas Supply

This ISO 21809 3LPE FBE steel pipe anti-corrosion coating line is a fully automatic, modular turnkey pipe coating production system engineered for factory-applied FBE and 3LPE anti-corrosion treatment of large-diameter steel pipes for water gas supply pipelines, oil and gas transmission, district heating pipe fabrication, municipal water supply networks, and buried pipeline infrastructure.

Certified to ISO 21809-1, DIN 30670, DNV, and SY/T0413 simultaneously - the most comprehensive multi-standard coating compliance available in this product category - this line delivers the broadest international certification coverage for global water gas supply pipeline EPC project bidding and regulatory approval.

Fusion Bonded Epoxy (FBE) powder is a non-toxic, thermosetting anti-corrosion coating material. After precision high-temperature curing at ± 2°C temperature accuracy, it forms a dense, high-molecular crosslinked protective film delivering outstanding chemical corrosion resistance, abrasion resistance, anti-aging performance, and high mechanical strength - meeting ISO 21809-1, DIN 30670, and DNV international standards for water gas supply and oil gas pipeline anti-corrosion coating.

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 water gas supply and oil gas pipeline anti-corrosion systems.

• ISO 21809-1 Multi-Standard Compliance: The internationally recognized multi-layer polymer coating standard for steel pipelines - ISO 21809-1 alongside DIN 30670, DNV, and SY/T0413 gives this water gas supply pipeline coating line the most comprehensive certification coverage for global EPC project compliance
