ISO 21809-2 Fusion Bonded Epoxy (FBE) Coated Line Pipe

ISO 21809-2 Fusion Bonded Epoxy (FBE) Coated Line Pipe

Our ISO 21809-2 fusion bonded epoxy (FBE) coated line pipe is designed to meet the stringent requirements of the international standard ISO 21809-2 for coatings for pipes and fittings for pipelines in petroleum and natural gas industries. The FBE coating is applied through a process of fusion bonding, where a thin layer of epoxy resin is applied to the pipe surface and then cured at high temperatures, resulting in a strong, durable, and corrosion-resistant coating. The coating provides excellent resistance to acidic and alkaline environments, as well as protection against mechanical damage and abrasion. Our ISO 21809-2 FBE coated line pipe is widely used in various applications, including oil and gas transportation pipelines, offshore platforms, and land-based infrastructure projects. With its excellent performance characteristics, our FBE coated line pipe ensures reliable operation, reduced maintenance costs, and extended lifespan of the pipeline system.
