1 Inch 2 Inch Galvanized Iron Steel Pipe

      Hot dip galvanized pipe is made of molten metal and iron matrix reaction to produce alloy layer, so that the matrix and the coating of the two combination. Hot dip galvanizing is to first pickling the Steel Pipe. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned by ammonium chloride or zinc chloride aqueous solution or mixed aqueous solution of ammonium chloride and zinc chloride, and then sent 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 matrix of hot-dip Galvanized Steel Pipe and the molten bath in the spay, and a compact zinc-iron alloy layer with corrosion resistance is formed. The alloy layer is integrated with the pure zinc layer and the steel tube matrix, so its corrosion resistance is strong.

      Hot-dip Galvanized Steel pipe is widely used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facilities, agricultural machinery, petroleum machinery, mining machinery, greenhouse construction and other manufacturing industries.
