Galvanized steel pipes are categorized into cold galvanized and hot galvanized pipes. The former has been banned, while the latter is still temporarily approved by the state. In the 1960s and 1970s, developed countries began to develop new types of pipes and subsequently banned the use of galvanized pipes. China's Ministry of Construction and other four ministries issued documents clearly stating that galvanized pipes should not be used as water supply pipes from 2000 onwards. Galvanized pipes are rarely used in cold water pipes of new residential complexes, while some complexes still use them for hot water pipes. Hot galvanized steel pipes are widely applied in fire prevention, electricity, and highways.

Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mining, chemicals, electricity, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, oil machinery, prospecting machinery, and more.

Galvanized steel pipes are焊接steel pipes with a hot-dipped or electro-galvanized zinc coating on the surface. The galvanizing enhances the corrosion resistance of the pipes, extending their service life. These pipes are widely used for various applications, including general low-pressure fluid pipelines for water, gas, oil, and more. They are also employed in the oil industry, particularly for oil well pipes and oil pipelines in offshore oil fields. Additionally, they serve as oil heaters, condensers, and coolers in petrochemical coking equipment, as well as for bridge pier piles and support pipes in mining tunnels.
