Corrosion of stainless steel (316L) storage tanks for atmospheric pressure sulfuric acid
Thread Content
Are you all facing the corrosion problem with atmospheric-pressure stainless steel (316L) sulfuric acid storage tanks again? Concentrations of 78% and 92%, temperature: 50°C. Thank you!
Yes, atmospheric-pressure stainless steel (316L) sulfuric acid storage tanks are prone to corrosion at concentrations of 78% and 92% at a temperature of 50°C. This is because sulfuric acid has strong oxidizing and corrosive properties, and the corrosion resistance of stainless steel at normal pressure (316L) also has certain limitations. It is recommended to use more corrosion-resistant materials or adopt anti-corrosion measures, such as applying acid-resistant coatings or installing linings, in order to reduce the risk of corrosion. At the same time, regular inspections and maintenance are also very important. .
No metal material can be used for 98% sulfuric acid. Consider fiberglass or steel-lined PTFE
Spray a layer of corrosion-resistant material on the surface; the temperature isn’t high. It's very simple. Add zhizhu*a88888 if needed
92% sulfuric acid is less corrosive, while 78% sulfuric acid cannot be used.
