Galvanized pipes are products obtained by galvanizing ordinary steel pipes, and galvanizing can increase the corrosion resistance of the steel pipes and extend their service life.

[0003] Galvanized pipes need to be formed by heating and welding, and after forming, they need to be cooled down. Therefore, cooling devices are used. Currently, most cooling devices use water cooling to cool galvanized pipes. The efficiency of single water cooling is relatively low, and a large amount of cooling water needs to be consumed.
