Abstract

Procedure for continuously manufacturing galvanized tube with a coated inner surface from flat steel strip, characterized in that it comprises the operations of: supplying flat steel strip from a supply source of said material, continuously giving the flat strip of steel a tubular configuration and continuously applying a layer of a compound comprising a coloring agent and a thermally curable binder at a relatively high temperature on the surface of the flat strip that forms the inner wall of the formed tube; continuously weld the seam formed by the side edges of the band; and passing the tube formed by a molten zinc bath to galvanize it while, at the same time, the compound applied to the inner wall of the tube formed is hardened.
