Some questions regarding the corrosion rate of concentrated sulfuric acid
Thread Content
Help, please! I’m a student and have been working at a *company recently. Then, there are many issues regarding the corrosion of carbon steel by concentrated sulfuric acid; I hope those with more experience can share their insights. Thank you very much. I mainly want to ask: what is the relationship between the corrosion rate of carbon steel pipes by concentrated sulfuric acid and temperature, internal and external pressures, as well as flow velocity? It would be great if there are graphs available. Thank you all**, with three bows

Mm-hmm, the flow rate issue seems to be resolved. There’s still the matter of the impact of temperature and internal/external pressures on 98% concentrated sulfuric acid, but thanks anyway~~~
There shouldn’t be any issues with the temperature; you can use carbon steel lined with polytetrafluoroethylene – polytetrafluoroethylene is resistant to acids and has good temperature resistance! If you are just doing research, then go look for literature! I can’t answer that for you;P
