Relevant utilization of galvanized pipes
To improve the corrosion resistance of steel pipes, general steel pipes are galvanized. Galvanized steel pipes are divided into two types: hot-dip galvanizing and electrogalvanizing. The hot-dip galvanizing layer is thick, the cost of electrogalvanizing is low, and the surface is not very smooth. Oxygen blowing welding pipe: used for oxygen blowing in steelmaking, generally using small diameter welded steel pipes, with specifications ranging from 3/8 to 2 inches. Made of 08, 10, 15, 20, or 195-Q
