(OP)
Hi guys,
I need to put superheat value to datasheet for psv of the seal gas heater...
Could you please advise how can I define the superheat?
Thanks,

RE: superheat
RE: superheat
I assume we are talking about a steam relief case. At the controlling scenario for sizing you will have determined not only the flow but the relieving pressure (set pressure + allowable overpressure) and a co-incident temperature. Go to the steam table and look up the saturated steam temperature that corresponds to your relieving pressure. The difference between the co-incident relieving temperature and this saturated temperature is the degrees of superheat the PSV specification is looking for.
