The hot-dip galvanizing process is a relatively stable and reliable steel surface treatment solution to resist environmental corrosion. There are many factors that affect hot-dip galvanizing, such as: steel substrate composition, surface state (such as roughness), substrate internal stress, geometry The thickness of the base material has a greater impact on the thickness of hot-dip galvanizing, and generally the thicker the steel pipe is, the greater the thickness of hot-dip galvanizing. According to the requirements of the national standard, the local thickness of hot-dip galvanizing should not be less than 56μm, and the average thickness should not be less than 70μm.
If you want to further improve the anti-rust effect of galvanized steel pipe, you can use the method of physical anti-rust, that is, brush a layer of anti-rust paint or spray a layer of anti-rust paint on the surface.
