The hot-dip seamless tube is obtained by reacting a molten metal with an iron matrix to produce an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first, in order to remove the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. The steel pipe matrix and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant structure of a zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base. Therefore, its corrosion resistance is strong.
At present, the company has carried out galvanizing business with local local galvanizing manufacturers for more than ten years. The products sold are widely used in nuclear power plant construction, urban construction, and steel plant thermal power plant infrastructure construction. It has three hot-dip galvanizing production lines. The largest zinc pot is 16.5 meters long, 3 meters wide and 3 meters deep. The second zinc-plating production line has a zinc pot length of 15 meters, a width of 2.6 meters and a depth of 3 meters. The third zinc-plating production line has zinc. The pot is 7 meters long, 1.5 meters wide and 1.5 meters deep. The total hot-dip galvanizing workshop covers an area of more than 20,000 square meters. It is the largest hot-dip galvanizing enterprise with the largest processing capacity and the most advanced technology in the same industry in North China.
