Epoxy powder Electrostatic spraying cannot be used for spraying the inner surface of steel pipes, because the inner surface is not easily charged, nor can fluidized bed dip coating be used, but epoxy powder spraying can be used. Preheating generally uses a seam furnace to heat and take out the tubes one by one for spraying. Natural gas or liquefied petroleum gas can also be used to heat the tubes to a temperature above the powder melting temperature according to the diameter and wall thickness of the tubes. Spray epoxy powder on the inner wall of the steel pipe. During spraying, the preheated steel pipe is placed on the rotating bracket, and the spray gun head moves along the axis direction.
