Product Description
Galvanized steel pipe is an alloy layer formed by the reaction between molten metal and iron matrix, which combines the matrix and the coating. Hot-dip galvanizing is a process of pickling steel pipes. In order to remove the iron oxide on the surface of steel pipes, after pickling, the pipes are cleaned through ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent into the hot-dip galvanizing tank.
