Galvanized Pipe

Galvanized steel pipes are categorized into cold galvanized and hot galvanized types. Cold galvanized pipes are now banned, while hot galvanized pipes are still temporarily recommended by the state. In the 1960s and 1970s, developed countries internationally began developing new types of pipes and progressively banned the use of galvanized pipes. China's Ministry of Construction and other four ministries issued documents clearly stating the ban on the use of galvanized pipes as water supply pipes starting from 2000. New residential complexes rarely use galvanized pipes for cold water pipes, while some use them for hot water pipes. Hot galvanized steel pipes are widely used in firefighting, electricity, and highways.

Galvanized steel pipes are widely used in the manufacturing industries such as construction, machinery, coal mines, chemical industry, railway vehicles, automotive industry, highways, bridges, containers, sports facilities, agricultural machinery, oil machinery, prospecting equipment, and more.

Galvanized steel pipes with a hot-dipped or electro-galvanized zinc coating. The galvanizing enhances the corrosion resistance of the steel pipes, extending their service life. These pipes find wide applications, serving not only as pipeline tubes for general low-pressure fluids like water, gas, and oil but also as oil well and pipeline tubes in the petroleum industry, particularly for offshore oil fields. They are used in chemical and coking equipment for oil heaters, condensers, and coolers, as well as for stack bridge piles and support tubes in mining tunnels.
