Hot dip galvanized pipe
Hot-dip galvanized pipe is to react the molten metal with the iron
matrix and produce an alloy layer, so that the matrix and the
coating are combined. Hot-dip galvanizing is the first pickling of
the steel pipe. In order to remove iron oxide on the surface of the
steel pipe, after pickling, it is cleaned by an ammonium chloride
or zinc chloride aqueous solution or a mixed aqueous solution of
ammonium chloride and zinc chloride, and then enters the hot-dip
galvanized steel pipe. Dip plating tank. Hot-dip galvanizing has
the advantages of uniform coating, strong adhesion and long service
life. The hot-dip galvanized steel pipe undergoes a complex
physical and chemical reaction with the molten bath to form a
zinc-iron alloy layer with dense structure and corrosion
resistance. The alloy layer is integrated with the pure zinc layer
and the steel pipe matrix, and has strong corrosion resistance.
