Hot Dipped Galvanized Iron round pipe/Galvanized erw Steel Tubes/Tubular carbon Steel pipesfor greenhouse building construction
Product Description
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.
hot-dip galvanized seamless steel pipe
If calculated according to the national standard, the average thickness is 70μm, the amount of zinc attached is 70x7.2=504g/m2, and the service life in four different environments is about:
Heavy industrial park: 12 years, the annual corrosion rate is 40.1;
Coastal area: 46 years with a corrosion rate of 10.8 per year;
Suburban areas: 93 years, with an annual corrosion rate of 5.4;
Urban areas: 28 years with an annual corrosion rate of 17.5;
Hot-dip galvanized seamless pipe is processed by pickling and rust removal, zinc pool galvanizing, surface passivation and other processes, so that the zinc pool is firmly attached to the surface of the steel pipe. Galvanized seamless steel pipes last longer.
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.
