P235gh Round Galvanized Steel Pipes
Hot dip galvanized steel pipe with pickling, first to remove iron
oxide on the surface of the steel tube, after acid cleaning, by
ammonium chloride or zinc chloride or ammonium chloride and zinc
chloride mixed aqueous solution tank cleaning, and then sent to the
hot dip plating tank. Hot dipped galvanized zinc layer thickness,
coating uniformity, strong adhesion, long service life, etc. Steel
substrate with molten electrolyte solution in complex physical and
chemical reaction, the formation of corrosion resistance of the
structure compact zinc alloy layer. Pure zinc layer, alloy layer
and steel substrate fused together .So the corrosion resistant
ability.
