Must a flame arrester be installed on combustible gas pipelines?

Recently, I came into contact with a sulfur processing unit and found that no flame arresters were installed for either the acidic gases or the gas fed into the furnace. When I asked the relevant personnel, they said that the design team had taken this into account; the exact reason is unknown Therefore, I would like to ask the experts here: could you please explain the reasoning behind this? Thank you very much!
It would be great if there were pictures! ! ! ! ! ! ! ! !
I have indeed encountered the situation of acid gas tempering, where the pipeline gets burned through right away.
Finally, I found the more official regulations. Here, the pressure before entering the gas separator tank is 0.4 MPa (gauge), but there is a dedicated interlock for low gas pressure, so it’s not necessary to install a flame arrester! Is Yu Gong attending the sulfur annual conference this time? From Nanchang!
