Hot dip galvanized steel tube Q215A Q215B Q235A Q235B OD 55mm wall thickness 3mm
Hot dip galvanized tube is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and coating of the combination of the two.Hot dip galvanizing is the first steel pipe pickling, in order to remove iron oxide on the surface of the steel pipe, 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 hot dip galvanized steel tube and molten plating solution to form a tightly structured zinc-ferroalloy layer with corrosion resistance.The alloy layer is integrated with pure zinc layer and steel tube matrix, so its corrosion resistance is strong.
