Galvanized steel pipe is divided into cold galvanized steel pipe and hot-dip galvanized steel pipe. Cold galvanized steel pipe has been banned, and the latter is also advocated by the state to be used temporarily. In the 1960s and 1970s, developed countries in the world began to develop new pipes, and galvanized pipes were banned one after another. China's Ministry of construction and other four ministries and commissions have also made it clear that galvanized pipes have been banned as water supply pipes since 2000. Galvanized pipes are rarely used in cold water pipes in new communities, and galvanized pipes are used in hot water pipes in some communities. Hot dip galvanized steel pipe is widely used in fire fighting, electric power and expressway
