Galvanized steel pipe
Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Hot-dip galvanized steel pipes are widely used in construction, machinery, coal mines, chemicals, electric power, railway vehicles, automobile industry, roads, bridges, containers, sports facilities, agricultural machinery, Petroleum machinery, prospecting machinery, greenhouse construction and other manufacturing industries.
Hot dip galvanized round steel pipe
Hot-dip galvanized seamless steel pipe structure: Hot-dip galvanized steel pipe is to make the molten metal react with the iron substrate to form an aluminum alloy layer, so that the substrate and the coating are closely combined. The hot dip galvanized round steel pipe is to pickle and passivate the seamless steel pipe first. In order to better remove the compound on the surface of the seamless steel pipe, after pickling and passivation, it is treated with ammonium chloride or magnesium chloride solution or a mixed solution of ammonium chloride and magnesium chloride. Cleaning is carried out in the middle, and then sent to the hot-dip coating tank. 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 produce complex physical and chemical changes, forming a corrosion-resistant zinc-nonferrous metal layer with a close structure. The aluminum alloy layer is integrated with the pure zinc layer and the seamless steel pipe base material. Therefore, it has strong corrosion resistance.
Galvanized strip pipe
Galvanized pipe structure: Galvanized pipe has adjusted the production process of hot dip galvanized round steel pipe. First carry out pickling and passivation on the useful hot-rolled strip steel, in order to better remove the compounds on the surface of the hot-rolled strip steel, after pickling and passivation, use ammonium chloride or magnesium chloride solution or a mixed solution of ammonium chloride and magnesium chloride in the tank It is cleaned and then sent to the hot-dip coating tank. It is then blow-dried and made into a tube. It has a uniform and bright coating, and the amount of galvanizing is very small, which is lower than the production cost of hot dip galvanized round steel pipe. Its anti-corrosion ability is slightly weaker than hot dip galvanized round steel pipe!
The difference between hot-dip galvanized seamless steel pipe and galvanized strip pipe
The color of hot dip galvanized round steel pipe is a bit whitish; 6 meters long and KG (strong anti-corrosion ability, long service life, slightly higher price). The color of the galvanized steel pipe is slightly whitish; the length of 6 meters is KG (the corrosion resistance is stronger and weaker, the service life is shorter than that of hot-dip galvanized steel pipe, and the price is cheap and economical). The difference between the two: hot dip galvanized round steel pipe is snow white but does not emit light or return light. There are few small snowflakes, and the mouths on both sides are clean and free of zinc tumors.
