Hot-dip galvanized steel pipes are widely used in the manufacturing industries, including construction, machinery, coal mining, chemical industry, electricity, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, oil machinery, prospecting equipment, and greenhouse construction.

Galvanized steel pipes are焊接steel pipes with a surface coating of hot-dipped or electro-galvanized zinc. The galvanizing enhances the corrosion resistance of the pipes, thereby extending their service life. These pipes find extensive applications, not only as pipeline tubes for transporting water, gas, oil, and other low-pressure fluids, but also as oil well and oil pipeline tubes in the petroleum industry, particularly for offshore oil fields. They are used in oil heaters, condensers, and coolers for petrochemical and coking equipment, as well as for pile tubes in bridges and support tubes in mine tunnels.
