An epoxy coated steel pipe is a product where a layer of epoxy resin is applied to the steel pipe surface, forming a continuous and robust anti-corrosion barrier. It is primarily categorized into two types: Fusion Bonded Epoxy (FBE) coating and Liquid Epoxy coating. Among them, FBE coating, due to its outstanding performance, has become the preferred standard technology for external corrosion protection of buried and submerged pipelines in industrial sectors.
