ISO9001 Q195 Q345 Material Galvanized Steel Pipe Hot Dipped For
Construction
Product Description
The hot-dip galvanized 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 the pickling, it is cleaned in a tank with
ammonium chloride or zinc chloride aqueous solution or a mixed
aqueous solution of ammonium chloride and zinc chloride, and then
sent to In the hot dip plating tank. Hot-dip galvanizing has the
advantages of uniform coating, strong adhesion and long service
life. The matrix of the hot-dip galvanized steel pipe undergoes a complex physical and chemical reaction with the molten
plating solution to form a corrosion-resistant zinc-iron alloy
layer with a compact structure. The alloy layer is integrated with
the pure zinc layer and the steel pipe matrix, so its corrosion
resistance is strong.
