Product functions and features
The hot-dip galvanized pipe is made by reacting the molten metal with the iron substrate to generate an alloy layer, thereby combining the substrate and the plating layer. Hot-dip galvanizing is to pickle the steel pipe first. In order to remove iron oxide on the surface of the steel pipe, after pickling, it is washed in an ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to the tank. Hot dip plating bath. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized steel pipe substrate and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant and dense zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe base, so its corrosion resistance is strong.

The field of application
Used in construction, machinery, coal mine, chemical industry, electric power, railway vehicles, automobile industry, highway, bridge, container, sports facility, agricultural machinery, petroleum machinery, prospecting machinery and other manufacturing industries.
