Style

1.Hot-dip galvanized steel pipe structure: Hot-dip galvanized pipe is the reaction of molten metal and iron substrate to produce an alloy layer, so that the substrate and the coating

The two are combined. The hot-dip galvanized steel pipe is first pickled, in order to remove the 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. Hot dip galvanizing into the hot dip plating bath 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, tightly-structured zinc-iron alloy layer. The alloy layer is integrated with the pure zinc layer and the steel pipe substrate, so its corrosion resistance is strong.

2. Galvanized strip tube structure: The galvanized strip tube has adjusted the production process of hot-dip galvanized tube. First perform the strip steel

Pickling, in order to remove the iron oxide on the surface of the strip, after pickling, it is washed in a tank of ammonium chloride or zinc chloride aqueous solution or a mixed solution of ammonium chloride and zinc chloride, and then sent to the hot dip plating tank. Then air-dried and made into tubes. It has a uniform and bright coating and a small amount of galvanization, which is lower than the cost of producing hot-dip galvanized pipe. Its corrosion resistance is slightly worse than hot-dip galvanized pipe!
