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steel pipes with a thermal dipping or electro-galvanized zinc coating on their surface. The galvanizing increases the corrosion resistance of the pipes, thereby extending their service life. These pipes have a wide range of applications, including not only as pipeline pipes for transporting water, gas, oil, and other general low-pressure fluids, but also as oil well pipes and oil pipelines for the petroleum industry, particularly offshore oilfields. They are used in oil heaters, condensers, and coolers for chemical and coking equipment, as well as in pipes for pier piles and supports in mine tunnels.
