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