Fused epoxy resin, also known as FBE coating, is a thin thermosetting polymer coating formed by electrostatic spraying of epoxy resin powder material on the surface of the base steel pipe. FBE coating has excellent corrosion resistance. It is firmly combined with the coating on the surface of the steel pipe base, extending the service life of the steel pipe and providing constant soil pressure.
FBE coating has excellent adhesion and resistance to cathodic stripping, and is widely used in the internal and external anti-corrosion of oil and gas pipelines. As an external anti-corrosion coating, FBE mainly includes single-layer FBE coating, double-layer FBE (DPS) coating, three-layer extruded polyethylene (3LPE), etc., which can achieve long-term anti-corrosion protection of pipes and pipelines. Combine them with cathodic protection.
Fused Bonded Epoxy (FBE) Coated Line Pipe
Fused-bonded epoxy (FBE) coatings protect pipe surfaces from corrosion. Double or triple layers of FBE can even increase wear resistance. FBE coating is also used as a primer layer in a 3-layer PE/PP coating system.
Electrostatic epoxy powder is typically sprayed onto pipes at temperatures around 220 – 235°C. After reaching the hot pipe surface, the epoxy powder melts and forms a uniform layer of epoxy coating on the pipe.
The internal FBE coating is used to protect the inner surface of the steel pipe from corrosion and minor mechanical shock and provides excellent resistance to cathodic stripping.
In-house fused epoxy (FBE) systems are based on an epoxy powder coating system mounted on a spray gun. The spray gun moves through the pipe as the epoxy powder is sprayed onto the inside surface of the pipe. The pipe must be heated to melt the epoxy powder onto the pipe. After FBE application, the layer needs to be cured.
FBE can be applied at service temperatures up to 110 degrees Celsius; typical thicknesses are 350 to 450 microns. The second layer provides the pipe itself with excellent resistance to damage, even in the most difficult environmental conditions.
