Hot-dip galvanized steel pipes are widely used in the manufacturing industries such as 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 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 extensive applications, not only as pipeline tubes for general low-pressure fluids like water, gas, and oil, but also as oil well pipes and oil pipelines in the petroleum industry, particularly for offshore oil fields. They are used in oil heaters, condenser coolers, and coal distillation oil exchange tubes for petrochemical coking equipment, as well as for pier piles and support tubes in mine tunnels.
