Hot dip galvanized pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and the coating of both.Hot galvanizing is the first pipe pickling, in order to remove the surface of the steel pipe iron oxide, pickling, through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank for cleaning, and then into the hot dip plating tank.Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.Complex physical and chemical reactions occur between the base of hot-dip galvanized steel tube and molten plating solution, forming a corrosion-resistant zinc-ferroalloy layer with compact structure.The alloy layer is integrated with the pure zinc layer and the steel tube matrix, so its corrosion resistance is strong
