Galvanized round pipe welded pipe

Short Description:

Galvanized steel pipes are divided into two types: hot-dip galvanizing and electro-galvanizing. The hot-dip galvanizing layer is thick, the cost of electro-galvanizing is low, and the surface is not very smooth. Oxygen-blowing welded pipe: used for steel-making oxygen-blowing pipes, generally small-diameter welded steel pipes, with eight specifications ranging from 3/8 to 2 inches. Use 8, 10, 15, 20 or It is made of 195-Q235 steel strip, in order to prevent corrosion, it is necessary to carry out aluminizing treatment.

Galvanized steel pipes are divided into two types: hot-dip galvanizing and electro-galvanizing.

Hot-dip galvanized welded pipe is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined. Hot-dip galvanizing is to first pickle the steel pipe. In order to remove the iron oxide on the surface of the steel pipe, after pickling, it is cleaned in a tank with ammonium chloride or zinc chloride aqueous solution or a mixed aqueous solution of ammonium chloride and zinc chloride, and then sent to In the hot dip plating tank. Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life.

Cold galvanizing is electro-galvanizing, and the amount of galvanizing is very small, only 10-50g/m2, and its corrosion resistance is much worse than that of hot-dip galvanized pipes.
