Can be hot galvanized or cold galvanized
Galvanized pipe can be hot galvanized or cold galvanized.
Hot-dip galvanized pipe is the steel pipe immersed in high temperature molten zinc liquid to form a layer of solid zinc-iron alloy coating, which has high adhesion and can provide excellent corrosion resistance, while cold galvanized pipe is coated with a thin layer of zinc on the surface of the steel pipe by electrochemical method, the coating thickness is thin, and the corrosion resistance is relatively poor.
The coating of hot-dip galvanized pipe is thicker, generally reaching 50 to 120 microns, which can effectively block the erosion of external oxygen and water and provide a longer protective effect, while the coating of cold galvanized pipe is relatively thin, generally between 5 and 30 microns.
