                      • Galvanized Steel Pipe

                        Galvanized steel pipe divided into cold galvanized steel pipe, hot dip galvanized steel pipe.Galvanized steel pipe surface has hot-dip galvanized layer or electric galvanized layer.Hot galvanized pipe is molten metal and the iron matrix reacting alloy layer, so that the substrate and coating combination of both. Hot-dip galvanizing is the first steel pickling, in order to remove the steel surface of the iron oxide, after pickling, a mixed aqueous solution tank cleaning by aqueous ammonium chloride or zinc chloride or ammonium chloride and zinc chloride, and then into hot-dip plating bath. HDG has a uniform coating, strong adhesion, long life and other advantages.
