Hot-dip Steel Galvanize Pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in an ammonium chloride or zinc chloride aqueous solution tank, and then sent to a hot-dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.
The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so it has strong corrosion resistance.
