What is the form of the rupture disc?

What are the types of rupture disks among the safety accessories used for pressure vessel shells? How to choose?
Blowout discs are mainly divided into two types: positive arch type and negative arch type. The normal arch type is inexpensive but has a short lifespan; it cannot withstand vacuum conditions, and vacuum brackets need to be installed if such conditions exist. It produces fragments during detonation, so safety valves cannot be used for isolation. The inverse arch type is slightly more expensive, has a longer lifespan, can withstand complete vacuum conditions, and produces no fragments during detonation, thus allowing the safety valve to be isolated. To determine the specific selection, please provide the relevant process parameters, and I will help you choose.
