Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemicals, electricity, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, oil machinery, prospecting equipment, and greenhouse construction.
Galvanized steel pipes are焊接钢管with a hot-dipped or electro-galvanized zinc coating on the surface. The galvanizing increases the corrosion resistance of the pipes, extending their service life. These pipes are widely used, not only as pipeline tubes for transporting water, gas, oil, and other low-pressure fluids, but also as oil well pipes and oil transportation pipes in the petroleum industry, especially for offshore oil fields. They are also used for oil heaters, condensers, and coolers in petrochemical coking equipment, as well as for pile tubes in bridges and support tubes in mine tunnels.
