Hot-dip galvanized pipe is made by reacting molten metal with iron substrate to produce an alloy layer, thus combining both the substrate and the plating layer. Hot-dip galvanizing is done by pickling the steel pipe first, in order to remove the iron oxide on the surface of the pipe, and after pickling, it is cleaned by ammonium chloride or zinc chloride in aqueous solution or mixed ammonium chloride and zinc chloride in aqueous solution bath, and then sent to a hot dip plating bath.
