Outlet line size of PRV
Outlet line size of PRV
(OP)
Dear Sir,
During review the P&ID, I saw PRV out let line size is less than inlet line size. is it possible ?
PRV having 4.5 barg set pressure & connected with LP flare header.
I understand inlet line size & outlet line size govern by different factors like but usually outlet line size is greater than inlet line size.
Please guide me at that matter . thanks in advance

It's possible this installation is OK - but I can't say since you referenced the in/out pipe size rather than the in/out PSV size.

Anyway, if you share some basic data a quick check could be made to give a more professional answer; as a minimum:
- set pressure and back pressure
- mass flowrate and density of fluid
- vapor fraction at in/out conditions
- in/out size of PSV and lines
