The service life of hot-dip galvanized seamless pipe is very long. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized steel pipes used in cities can reach 30 years, and galvanized steel pipes used in other corrosion-prone areas have a longer service life. How long they can be used mainly depends on the thickness of the galvanized layer of the steel pipe.
After galvanizing, the steel pipe has actually played an anti-rust role, and no other anti-rust treatment is required. If you want to further improve the anti-rust effect, you can use physical anti-rust methods, that is, brush a layer of anti-rust paint on the surface or spray a layer of anti-rust paint.
