For PH2-3, which mainly contains sodium sulfate and sulfuric acid an, what material should be used? Can 304 withstand it?
304 is resistant to nitric acid but not to sulfuric acid. A test can be done on 304; using plastic is fine, and 316L is even better.
Let’s take a look at glass-lined storage tanks. Corrosion resistance: They exhibit excellent resistance to corrosion in the presence of various concentrations of inorganic acids, organic acids, organic solvents, and weak bases. However, it is not suitable for strong bases, hydrofluoric acid, and fluoride-containing media, as well as for phosphoric acid at temperatures above 180°C and concentrations above 30%
Fiberglass; 304 is not suitable; you can check the corrosion manual
It depends on the storage volume; for volumes of 0.5–1 cubic meter, fiberglass can be used
