Material selection for hydrochloric acid storage tank (at atmospheric pressure)
Thread Content
As the title suggests—what material should be used for the main body of the hydrochloric acid storage tank (at atmospheric pressure)? Can 304 or 316 materials be used?
Using 304 for hydrochloric acid is like aiming the gun at oneself.:lol:lol
Fiberglass-reinforced plastic presents many problems down the line, so it’s not a viable option; we use vertical tanks with a PTFE lining

For hydrochloric acid storage tanks, steel-lined PTFE tanks or fiberglass-reinforced plastic tanks should be used; steel tanks will suffer from severe corrosion
