[0002] Galvanized steel pipes are welded steel pipes with hot-dip or electroplated zinc layers on their surfaces. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, oil heaters, condenser coolers, coal distillation and washing oil exchangers for chemical coking equipment, as well as pier pipe piles and support frames for mine tunnels.

[0003] In the related art, during the galvanizing process, steel pipes are usually hot-dip galvanized by hoisting them with ropes. This method is prone to shaking when the steel pipes are lifted or lowered.
