What is the initial step in the FBE application process?

In the FBE (Fusion Bonded Epoxy) application process, the initial step is to preheat the pipe. Preheating is crucial because it ensures that the FBE powder adheres properly to the surface of the pipe when applied. The preheating process typically involves raising the surface temperature of the substrate to an optimal level, which helps to enhance the flow of the powder coating and promotes a strong bond between the epoxy and the substrate upon application.

By preheating the pipe, it allows the FBE coating to melt and uniformly cover the surface, which is critical for achieving the desired protective properties. This step significantly affects the final quality and durability of the coating, making it an essential part of the application process.
