Hot dip Galvanized Steel Pipe is to make molten metal and iron matrix reaction and produce alloy layer, so that the matrix and the coating of the combination of the two. Hot dip galvanized Steel Pipe is first pickling steel pipe, 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 galvanized steel pipe has the advantages of strong corrosion resistance, not easy to rust, long life, relatively cheap price, etc..Hot dip galvanized steel pipe is more widely used in greenhouse, hot dip galvanized steel pipe is also widely used in construction, machinery, railway vehicles, automobile industry, fire protection, electric power and highway.
