What Is The Fbe Coating Of Spiral Welded Pipe?

FBE of spiral welded pipe is the abbreviation of the English name of Fusion Bonded Epoxy (FBE) "FUSION BOND EPOXY". There are two kinds of FBE coating for spiral welded pipe: single-layer and double-layer.

The so-called spiral welded pipe FBE coating generally refers to single-layer fusion bonded epoxy coating. The single-layer FBE coating adopts special fusion bonded epoxy powder coating as the film-forming material. This epoxy powder coating is a thermosetting coating, made of solid epoxy resin, curing agent and a variety of additives by mixing and crushing process.

FBE coated spiral steel pipe

Spiral steel pipe undergoes shot blasting and medium frequency preheating before painting, and then epoxy powder coating is sprayed on the surface of heated steel pipe by electrostatic spraying method, which is fused and bonded on the surface of the steel pipe and cured to form a coating.

Spiral steel pipe FBE coating is generally generally a film-forming structure, the film thickness is 300~500μm. Spiral steel pipe FBE coating has the advantages of strong adhesion to steel, good film integrity, resistance to cathodic stripping, resistance to soil stress and abrasion, but resistance to mechanical damage and resistance to heat and humidity is poor.FBE coating can be used for the working temperature of -30 ~ 100 degrees Celsius steel buried spiral steel pipe or underwater pipeline facilities of the external anticorrosion.
