DURING THE FBE PROCESS:

the pipe surface is cleaned and heated
epoxy powder is electrostatically applied onto the pipe
the powder melts onto the pipe and quickly dries into a uniform and controlled thickness 

coating pipe


工艺流程

Products description

Single-layer FBE coating uses special dissolved epoxy powder coatings as film-forming materials, and electrostatic spraying process is used to coat epoxy powder coatings, one-time film-forming. 

This kind of epoxy powder coating is a thermosetting coating, which is made of solid epoxy resin, curing agent and various additives by mixing and powder processing. The steel pipe is pre-heated by shot blasting and intermediate frequency before spraying. The epoxy powder coating is sprayed on the surface of the heated steel pipe by electrostatic spraying method. It is melted and bonded on the surface of the steel pipe and solidified into a coating. FBE coating is generally a primary film-forming structure.

Advantages:such as strong adhesion to steel, good film integrity, shade resistance, peeling resistance, soil stress resistance and wear resistance, simple coating operation, pollution-free, good resistance to resist and bend, high temperature resistance, etc. It has been widely used abroad. FBE coating can be used for external corrosion protection of steel buried pipelines or underwater pipeline facilities with working temperature of ~C. Epoxy powder is a thermosetting, non-toxic coating. After curing, it forms a high molecular weight cross-linking structure coating. It has excellent chemical corrosion resistance and high mechanical properties, especially the best wear resistance and adhesion.

Single-layer FBE coating 

Single-layer FBE coatings protect buried pipelines against corrosion and mechanical damage. The average layer thickness of this coating variant is 400 to 500 μm.

Two-layer FBE coating

The first layer of this coating type serves mainly for corrosion protection, while the second layer serves as mechanical protection in the case of increased external loads.

For the second layer, either the same material as for the first layer may be used or, in the case of applications involving increased service loads, an abrasion-resistant overlay (ARO). The second layer is particularly designed to provide protection against mechanical impact and abrasion. It is applied using the same technique as for the first layer (wet-on-wet) to an average minimum thickness of about 400 to 500 μm.

The second layer for non-buried pipelines, such as pipe bridges, consists of an UV-resistant polyester. It is also applied to a thickness of 400 to 500 μm.

In offshore projects, FBE is frequently combined with a ballast coat of cement mortar. In this case, the second FBE layer is usually applied as a so-called rough coat, which provides increased shearing resistance to prevent the cement mortar coat from slipping off as the heavy pipe string is lowered to the seafloor.
