In short, yes. But there is a but...
I would describe this as bad practice because you are regularly challenging the ultimate protection of the vessel - the 24" vent set. The taken wisdom is that more times you use something the more likely to fail next time. In effect you emergency relief...
I'd like to say 'don't panic', but that would be bad advice.
For all intents and purposes this is a 'water hammer' situation and unless the pipe is designed for these surge flows then time to failure is closer than you think.
You say it is a piston pump, so I am assuming it is mechanically...
@Anup87, I'd love to answer your question but I'm not sure exactly what it is. Can you give a little more detail?

@Miketheengineer, I've posted in pipelines as well but my try structural too. I appreciate this is a long shot and multiple posting is poor etiquette, but I know I've got to cast the net wide.

Does anyone have any experience of using spring hangers rather than bellows to isolate the load of a pipe on to a vessel, such that the pipe is 'isolated' in terms of impact on load cell readings?
"Are we speaking the same language?...engineering - it's the appliance of science."
I'm looking for somebody that has experience of using spring hanger pipe supports for pipes on to vessels that are on load cells.
We have been through this with our pipe stress engineers and they believe it is fine, as an alternative to using bellows/flexible. The problem is our end customer...
Gents,
Nice comments. Our client has their own variation on the two-phase flow calc. Which does cause problems. One hardly every says two-phase flow but the other usually does. However, they both disagree with DIERS/API521. Not to mention their own standard says you should design for...
don1980 you have got my full agreement on that, but how or what do I quote that stops people believing that they should consider 2-phase flow in the fire case. I've tried Fauske's work from CEP, ICI's PSG8, even the foreword of the HSE Workbook (UK's DIERS report) but all to no avail. They...
OK, folks open season on thoughts with regards Fires, DIERS and two-phase relief.
There is much deabte going on in the UK about the use of the "HSE Workbook" for the fire case scenario. For those of you outside the UK this is just the DIERS work restated in an easy to understand way.
What is...
