How to prevent corrosion of a 200 cubic meter 85% sulfuric acid storage tank?

Thread Content

Please tell me: I am making a 200 m3 85% sulfuric acid storage tank at normal temperature, using Q235-A. I would like to ask if using carbon steel also requires internal anti-corrosion. If so, is there any cheaper method besides lining with fluoroplastic (except lining with bricks)?

Is it okay to passivate with concentrated sulfuric acid before use? You can try this method! Cheap and practical!

Internal anti-corrosion is required, and it is best to be lined with fluoroplastic.
