Zirconium cut-off valve corrosion characteristics and application:


In all the hydrochloric acid concentration, temperature and higher than the boiling point, has excellent corrosion resistance, not easy to happen crevice corrosion, pitting corrosion and stress corrosion;


Zirconium cut-off valve in sulfuric acid can be resistant to the boiling point, and higher than the boiling point, concentration of less than 70% of the sulfuric acid medium;


In acetic acid can be resistant to the various concentration of acetic acid medium under 250 ℃, its almost no corrosion;


In various concentration of alkali solution is unique and molten alkali medium corrosion resistant material;


Zirconium cut-off valve in organic acid has very good corrosion resistance.
