Galvanized steel pipes are divided intocold galvanizingSteel pipehot-dip galvanizingSteel pipe,galvanizingSteel 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, petroleum machinery, and mining machinery.

Galvanized steel pipes with hot-dip or electroplated zinc coating on the surfacewelded steel pipeGalvanizing can increase the corrosion resistance of steel pipes and extend their service life.galvanized pipeIt has a wide range of applications. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, it is also used as oil well pipes and oil pipelines in the petroleum industry, especially in offshore oil fields. It is also used as pipes for oil heaters, condensers, and coal tar wash oil exchangers in chemical coking equipment, as well as for support structures in wharf piles and mining tunnels.
