In this case, the only available valve is the new ceramic ball valve. Hydrochloric acid medium: Most metal materials are not resistant to hydrochloric acid corrosion (including various stainless steel PTFE coated adhesive tapes materials), and high-silicon ferro-molybdenum can only be used in hydrochloric acid below 50°C and 30%. The corrosion of sulfuric acid with different concentrations and temperatures is quite different.
Sulfuric acid medium: As one of the strong corrosive media, sulfuric acid is an important industrial raw material with a wide range of uses. Nitric acid medium: most metals are quickly corroded and destroyed in nitric acid.For valves under corrosive medium conditions, anti-corrosion is the most critical part of chemical equipment. Therefore, the scientific nature of the material selection should be paid attention to when selecting the chemical [...]
