Hot dip galvanized round pipe is to make molten metal react with iron matrix to produce alloy layer, so as to combine the matrix and coating. 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, the steel pipe is cleaned in an aqueous solution of ammonium chloride or zinc chloride or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to a hot-dip plating tank. Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions take place between the substrate of hot-dip galvanized steel pipe and molten plating solution, forming a corrosion-resistant zinc-iron alloy layer with compact structure. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, it has strong corrosion resistance

Hot dip galvanizing has the advantages of thick coating, uniform coating, strong adhesion and long service life.
Galvanized pipes are now mainly used for transporting gas and heating. Galvanized pipes are widely used, not only as pipelines for transporting water, gas, oil and other general low-pressure fluids, but also as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields, oil heaters, condensation coolers, pipes for coal distillate washing oil exchangers in chemical coking equipment, pipe piles for trestle bridges and pipes for supporting frames in mine tunnels, etc. Galvanized pipes are used as water pipes. After several years of use, a large amount of rust scale is produced in the pipes, and the yellow water flowing out not only pollutes sanitary ware, but also mixes with bacteria that breed on the unsmooth inner wall. Corrosion causes excessive heavy metal content in water, which seriously endangers human health.
