Why we need PSV in cryogenic service? 3

Regardless of service, if you have pressure vessels/piping that can experience pressures higher than the design pressure, you need relief valves.
The sources of pressure could be process upsets, abnormal heat, control valve failure, fire, etc. If no credible scenario exists, then typically a small PSV for thermal relief would be adequate as long as you've documented all the non-credible cases in the calculation.
