Hot-dip galvanization (galvanization), also known as hot-dip galvanizing and hot-dip galvanizing, is an effective metal anti-corrosion method, which is mainly used in metal structure facilities in various industries. It is to immerse the derusted steel parts in molten zinc at about 500 ° C, so that a layer of zinc is attached to the surface of the steel parts, so as to achieve the purpose of anticorrosion. Hot-dip galvanizing process: finished product pickling-washing-adding auxiliary plating solution-drying-rack plating-cooling-medicinal chemistry-cleaning-polishing-hot-dip galvanizing is completed.

Hot dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. Complex physical and chemical reactions occur between the steel pipe substrate and the plating solution, forming a corrosion-resistant zinc-iron alloy layer with a tight structure. The alloy layer is combined with the pure zinc layer and steel pipe matrix. So its corrosion resistance is strong.

application:

Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and mining machinery.
