Sizing of Relief Devices

From http://www.cheresources.com/invision/index.php?showtopic=573:

<<We, the Process Engineer size them, period. And Art gave the correct definition of sizing. I am amazed that there are engineers out there that still think the vendor sizes rupture disks, relief valves and even relief piping and all they think they need to do is supply the flow rate and some fluid properties.

I also pretty much tell the vendor what I want even mechanically after discussing the applications with them. They are a great source for this but the owner is still responsible, not the vendor. I bring this up a number of times in my series on Rupture Disks, which, by the way you can find on this site (I got my plug in).>>

pleckner is right.

How can a vendor size when s/he doesn't know the whole system?

That's the process engineer's job.
