Pump Safety Valve Adequate? 1

[aparton]

I'm working on several high pressure steam lines, and currently the only relief on these lines is a safety valve built into the pump. I'm thinking this is inadequate, but I've been told by some senior engineers that it's fine. I've read through ASME code B31.1 and I can't find anything on the subject. Is it ok to rely just on the pump relief valve, or should there be a second relief valve somewhere else on the line, and is there any standards/codes/regulations that deal with this?

The relief valve on the pump is fine IF, you also look at the relief valve's location compared to block valves and check valves and recognize risks for failure of all the componets.

Now, I have to ask, are you pumping steam? or did you mean that the boiler feed water lines? In that case as stated above you are OK.

On the steam side, you steam piping is protected by the boiler's relief valve.

I'm sure there are probably SRVs on the boiler as well.
