Hot-dip galvanized steel pipes are widely used in the manufacturing industries such as construction, machinery, coal mines, 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 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 wide applications, not only as pipeline tubes for conveying water, gas, oil, and other low-pressure fluids, but also as oil well pipes and oil transportation pipes in the petroleum industry, particularly for offshore oil fields. They are used in oil heaters, condenser coolers, and coal distillation oil exchangers in chemical coking equipment, as well as in pile tubes for bridges and support tubes for mine tunnels.
