PSV on vessel i/l line
PSV on vessel i/l line
(OP)
Can anybody help me out, is there any standard that says about safety relief valve can not be installed on pressure vessel inlet line.
If vessel overhead nozzle & disharge line are smaller than PSV required orifice size, can that PSV be installed on vessel inlet line which is of higher size.
thanks,

Jonathan Livingston is correct, it can be installed on the inlet piping.
From a piping point of view it should be located so that it can be supported/restrained as required without having use springs etc.

We have this setup on some scrubbers that used Pall Rings where a change in operation required a new nozzle in the vessel for a larger valve. The time and expense to get a hot work and vessel entry required evaluating the placing of the PRV in the inlet line by means of a spool piece.
