Set the pressure pipe connection size for rupture valves and explosion discs. This is a phrase from the PID specifications provided by foreigners; I don’t understand what rupture valves are
Rupture valves: can be translated as safety valves (these valves achieve safety by the rupture of a diaphragm). Refer to: unidirectional membrance rupture valve – one-way membrane rupture valve
As the counterpart to a rupture disc, it can be translated as a burst valve
Agree with the person in floor 2. It should be a type of safety valve.
Specify the size of the connections between pressure pipelines and rupture valves serta explosion discs
