FBE coating steel pipe is fusion bonded epoxy coating steel pipe.It is a kind of external heat resin used for pipes.With a form of dry powder at thickness 400-600 microns on to the heated surface of pipe.Once the FBE coated on the pipe surface,the FBE film provides an extremely hard surface with great adhesion to the surface of pipe.The FBE layer in a even form and have good resistance to the chemical reaction.
The steel pipes are treated by shot blasting and intermediate frequency preheating before painting, and then the epoxy powder coating is sprayed on the surface of the heated pipe products by electrostatic spraying method, which is fused and bonded on the surface of the steel pipe and solidified to form a coating. FBE coating is usually one – step film – forming structure.
Features of fusion bonded epoxy(FBE) coating steel pipes:
- FBE coating is corrosion resistant and chemical resistant
- FBE coating has strong adhesion to steel, film integrity, soil stress and wear resistance.
- FBE coating increases the life span of steel pipes.
- The FBE coating can be used for external corrosion protection of buried or underwater steel piping installations with operating temperatures of -30~100 °c.
- On the other hand,the defect of the FBE steel pipe is it have poor resistance to mechanical damage and heat and humidity.
- A three-layer extruded polyethylene coating (3LPE) is composed of extruded, three-layer, anti-corrosive steel pipe coatings.

Double Layer FBE Coating Pipes
The double-layer FBE coating system consists of an FBE base coat covering the bare tube surface and a modified FBE top coat. The coating process of the 2 Layer FBE pipe is basically the same as the standard sintering FBE spraying process, except that the layout of the powder spraying chamber and spray gun has changed, without adding complicated equipment. There are two types of spray guns: double powder spraying chamber and integral powder spraying chamber. They are used in the double-layer FBE coating system, such as double powder spraying chamber spraying and integral powder spraying chamber spraying.
The performance characteristics of the double-layer FBE coating system have been proved by laboratory tests and field application tests. The double-layer FBE anti-corrosion system applied to buried steel pipelines has high bonding strength with the substrate, high resistance to cathodic peeling, and low water absorption. Good high-temperature resistance. The characteristic of this system is that it combines the higher bonding performance of standard FBE and substrate and the better water permeability resistance of modified FBE.
