Two problems with concentrated sulfuric acid
Thread Content
1. Can the glass flake lining in carbon steel storage tanks withstand concentrated sulfuric acid with a concentration of over 93? 2. Can aluminum alloy storage tanks withstand concentrated sulfuric acid? Thank you! :P :P :P :P :P :P
For concentrated sulfuric acid with a concentration of over 93%, carbon steel storage tanks are sufficient; there is no need for anti-corrosion measures. Concentrated sulfuric acid storage tanks can be made of ordinary iron materials, as iron can form a passivation layer with concentrated sulfuric acid, allowing it to be used for storage.
Agree with what was said above; for concentrated sulfuric acid with a concentration of 93% or higher, carbon steel storage tanks are sufficient, as an oxide layer forms on the surface of carbon steel, preventing corrosion
Storage of over 93% concentrated sulfuric acid in carbon steel tanks is sufficient, as the acid forms a passivation film with iron. Fuming sulfuric acid and dilute sulfuric acid at 5% or less can be treated with aluminum and aluminum alloys
Thank you, Floor 2345: What is the degree of corrosion caused by concentrated sulfuric acid with a concentration of over 93% on carbon steel? At 20 degrees and 50 degrees.
For sulfuric acid with a concentration of over 93, Q235 carbon steel equipment is sufficient, as the acid forms a dense passivation layer on the inner surface of the equipment, and this passivation layer itself provides corrosion protection!
