Hot Dipped Galvanized Steel Pipe
Hot-dip galvanized steel pipe in the installation to the steel parts are first pickled, to remove the iron oxide skin on the surface of the steel parts, after pickling, but also through the ammonium chloride or zinc chloride aqueous solution or a mixture of ammonium chloride and zinc chloride aqueous solution to clean, and then sent to the hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion, and long service life. Hot-dip galvanized steel pipe allows the molten metal and iron substrate chemical reaction, producing an alloy layer, so that the substrate and the plating are combined. The zinc layer of hot-dip galvanized steel pipe is thicker, with a thickness of 10um or more, and the surface is glossy but rough, and will appear shiny.
