Galvanized steel pipes are焊接s with a hot-dipped or electro-galvanized zinc coating on the surface. The galvanizing enhances the anti-corrosion capability of the pipes, extending their service life. These pipes find a wide range of applications, including as pipeline tubes for conveying water, gas, oil, and other low-pressure fluids. They are also used in the petroleum industry, particularly for oil well pipes and oil pipelines in offshore oil fields. Additionally, they serve as oil heaters, condensers, and cooling tubes for chemical and coking equipment, as well as for pile tubes in bridges and support pipes in mine tunnels.
