What are the criteria used to determine whether a bypass line is required for PSV safety venting?
There are no standard regulations specifying that bypasses can be used for air defense; they are not installed if there is no such need
A bypass line (CSC) is generally installed during the safety valve calibration period, when no other measures can be used to ensure that the system does not experience overpressure, or when it is necessary to discharge material through the safety valve’s bypass valve during startup or shutdown.
Is there something like this: two PSVs that enter together but leave at different times are not needed, while those that enter and leave together are required?； What about such small-scale standards?
Two safety valves were found in the temperature and pressure reduction unit, with different setting pressures: one corresponds to the maximum operating pressure, while the other is slightly higher than that value; this provides dual protection
Yes, it has different pressure protection options
