Is it necessary to install a flame arrester on the top of a stainless steel sulfuric acid storage tank?

Is it necessary to install a flame arrester on the top of a stainless steel concentrated sulfuric acid storage tank? I only saw one ventilation hole, and the company staff said it wasn’t necessary. Will it become diluted by absorbing water through this opening?
He can’t wear it again anyway, so why add a flame arrester? Moreover, the estimate of the amount of moisture in the air is too high. Moreover, carbon steel is more effective than stainless steel for storing and transporting concentrated sulfuric acid
Personally, I don’t think it’s necessary to include them, as ventilation holes are mainly used to balance the pressure inside the storage tank. It also has no effect on the acid concentration! However, adequate ventilation is still necessary when performing hot work in the tank area, as hydrogen will still be present in the pipes.
Does the poster mean a breathing valve? Older tanks used to have a simple vent opening, but in recent years, many of them have been equipped with breathing valves.
Does concentrated sulfuric acid not absorb moisture from the air? Why is carbon steel better than stainless steel? Please explain, thank you
Isn’t the presence of hydrogen in the pipeline the reason to install a flame arrester?
Is there any evidence to support the claim that carbon steel is more effective than stainless steel for storing and transporting concentrated sulfuric acid? It is recommended that you take a look at materials related to corrosion before making a decision. Although carbon steel can be passivated in concentrated sulfuric acid, its performance is still inferior to that of stainless steel. Because the passivation of chromium in stainless steel is more resistant to acid corrosion than that of iron.
Can acid mist corrode the lining and valve disc of the breather valve?
There will be some to some extent; those resistant to acid corrosion work!
