Studies have shown that the effect of alloying elements on improving the corrosion resistance of alloys comes from the stability of the passivation film formed on the surface of nickel alloys. The nickel content in nickel alloys is more than 30%, of which W(Ni+Fe)≥50% is called iron-nickel-based corrosion-resistant alloy, and W(Ni)≥50% is called nickel-based corrosion-resistant alloy. In actual use Zhongdu can be considered as a nickel-based corrosion resistant alloy

Application areas of nickel pipe flanges / nickel alloy flanges:

1. Ocean: Marine structures in the marine environment, seawater desalination, mariculture, seawater heat exchange, etc.

2. Environmental protection field: flue gas desulfurization device for thermal power generation, wastewater treatment, etc.

3. Energy field: nuclear power generation, comprehensive utilization of coal, sea tide power generation, etc.

4. Petrochemical industry: oil refining, chemical and chemical equipment, etc.

5. Food field: salt making, soy sauce brewing, etc.

In the above-mentioned many fields, ordinary stainless steel 304 is not competent. In these special fields, special stainless steel is indispensable and irreplaceable. In recent years, with the rapid economic development and the continuous improvement of the industrial field, more and more projects require higher-grade stainless steel. With the increase in demand for nickel-based alloys in various industries.
