Abstract: An uncured or partially cured, flexible fusion bonded epoxy (“FBE”) film for application to a metal substrate, such as an oil and gas pipeline pipe and pipeline pipe weld areas includes an epoxy resin, a curing agent, accelerator, filler, and optional additives. The epoxy can include a blend of solid epoxy resin and liquid epoxy resin. Also included are methods of applying the FBE film to pipe in the shop and on field joints. Methods also include using a flexible, electric heat blanket or heat belt to cure FBE film and epoxy liquid coatings on field joints.
