Product Brief Information

The hot-dip galvanized steel pipe is obtained by reacting a molten metal with an iron matrix to produce 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 the iron oxide on the surface of the steel pipe, after pickling, it is washed by ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then fed. Hot dip plating tank. Hot-dip galvanizing has the advantages of uniform plating, strong adhesion and long service life. The hot-dip galvanized steel pipe base and the molten plating solution undergo complex physical and chemical reactions to form a corrosion-resistant structure of a 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.

With the development of industry, hot-dip galvanizing products have been applied in many fields. The advantage of hot-dip galvanizing is that the anti-corrosion period is long, and adapting to the environment has always been a popular anti-corrosion treatment method. It is widely used in power towers, communication towers, railways, highway protection, streetlight poles, marine components, building steel structural components, substation ancillary facilities, light industry, etc. The anti-corrosion years of hot-dip galvanizing are long-term, but the years of anti-corrosion are different in different environments: 13 years in heavy industry, 50 years in the ocean, 104 years in the suburbs, and 30 years in the city.

The principle of hot-dip galvanizing: the iron parts are cleaned, then treated with solvent, dried and then immersed in zinc liquid. The iron reacts with the molten zinc to form an alloyed zinc layer. The process is: degreasing--washing--washing-- Co-plating - drying - hot dip galvanizing - separation - cooling passivation.

The thickness of the hot-dip galvanized alloy layer mainly depends on the chemical composition such as the silicon content of the steel, the cross-sectional area of the steel, the roughness of the steel surface, the zinc pot temperature, the zinc immersion time, the cooling speed, and the cold rolling deformation.

Advantages of hot dip galvanizing

1. The surface of the steel pipe is more durable with anti-embroidery treatment, not too fast oxidation, and will not form white rust on the steel pipe;

2. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave and convex parts are protected;

3. It has the characteristics of anti-corrosion and wear resistance, so that the steel pipe can be used for a longer time;

4. Since zinc has been plated on the outside of the steel pipe, the time for oiling or lacquering outside is omitted, and the construction is more convenient;

5. The galvanized steel pipe will not freeze and crack in three or nine days, and is especially suitable for the cold environment in the north.
