Galvanized steel pipes are divided into cold-plated pipes and hot-plated pipes. The former has been banned, and the latter has been promoted by the state to be temporarily available. Hot dip galvanized pipe is to make the molten metal react with the iron substrate to produce an alloy layer, thus combining the substrate and the coating. Hot galvanizing refers to the pickling of steel pipes. In order to remove iron oxide from the surface of steel pipes, after pickling, the steel pipes are cleaned in ammonium chloride or zinc chloride aqueous solution or ammonium chloride and zinc chloride mixed aqueous solution tank, and then sent to the hot dip galvanizing tank. Hot galvanizing has the advantages of uniform coating, strong adhesion and long service life. Most of the processes in the north adopt the zinc supplement process of direct coil of galvanized strip.

Cold galvanizing is electrical galvanizing. The amount of galvanizing is very small, only -g/m. Its corrosion resistance is much different from that of hot galvanizing pipe. In order to improve the corrosion resistance of steel pipes, galvanized steel pipes are generally used. Galvanized steel pipes are divided into hot galvanizing and electric galvanizing. The hot galvanizing zinc coating is thick, the cost of electric galvanizing is low, and the surface is not very smooth. Oxygen-blowing welded pipe: It is used as the pipe for oxygen blowing in steel making. Generally, it is welded steel pipe with small diameter, and the specifications are from /- inches. It is made of , , , or -Q steel strip. In order to prevent corrosion, some are subject to effective aluminizing treatment.
