Galvanized steel pipe is a steel pipe with zinc coating on the surface. Through the galvanizing process, the anti-rust and corrosion resistance of the steel pipe are enhanced. It has high strength and good machinability. It is widely used in building water supply and drainage, fire protection, gas transportation and other fields. It is a kind of pipe with excellent performance and wide use.

1. The appearance is usually silvery white, with a smooth surface.
2. It has high strength and hardness and can withstand certain pressures and external forces.
3. Excellent ductility and machinability, allowing for processing operations such as bending and cutting.
1. The galvanized layer provides good corrosion resistance, and the zinc oxide protective film formed by zinc in the air can prevent further oxidation of the steel pipe.
2. The galvanized layer has good stability in general acid and alkali environments, but corrosion may still occur under strong acid and alkali conditions.
3. Zinc is more reactive than iron, and in the event of corrosion, zinc is oxidized first to protect the steel tube matrix.
