Hot-dip galvanized steel pipes are widely used in manufacturing industries such as construction, machinery, coal mines, chemical industry, electric power, railway vehicles, automobile industry, highways, bridges, containers, sports facilities, agricultural machinery, petroleum machinery, and prospecting machinery.
Galvanized Steel Pipe Hot-dip or electro-galvanized welded steel pipe. Galvanizing increases the corrosion resistance of steel tubes and extends their service life. The use of galvanized pipe is very wide. Except for the general line of low pressure fluid such as water, gas, oil, etc., it is also used as oil well pipe and oil pipe in oil industry, especially in offshore oil field, and oil heater and condensation in chemical coking equipment. Cooler, coal distillate oil exchange pipe, and trestle pipe piles, mine pit support frame pipe.
Galvanized steel pipe is divided into cold galvanized steel pipe, hot-dip galvanized steel pipe, cold galvanized steel pipe has been banned, the latter also advocated for temporary use by the state. In the 1960s and 1970s, developed countries in the world began to develop new types of pipes and banned galvanized pipes one after another. China's Ministry of Construction and other four ministries also issued a document clarifying that galvanized pipes had been banned as water supply pipes since 2000, and galvanized pipes have rarely been used in newly constructed cold water pipes, and some district hot water pipes use galvanized pipes. Hot-dip galvanized steel pipes have a wide range of applications in firefighting, electricity, and highways.
