Vessel wall temperature

Vessel wall temperature

Vessel wall temperature

(OP)
Hi guys,

I am sizing the relieve valve for fire case and encountered with vessel wall temperature in rankine...

Could you please advise me which sourse of information I should use to get wall temperatures for different materials?

RE: Vessel wall temperature

From your wording, we cannot tell if you want information on the process material or the material used to build the vessel?  Please be more thorough.  We cannot read your mind.

Good luck,
Latexman

RE: Vessel wall temperature

If you look at ASME B31.3, table A-2, it shows you allowable stress limitations for different materials which kind of gives you an idea about what would be the maximum temperature the vessel wall composed of that material can withstand before failing. That Maximum Temperature is used for sizing.

Thanks.

RE: Vessel wall temperature

Remember tank for a tank with liquids in it the wall temperature is not important.

Best regards

Morten

MortenA,

So BLEVEs don't happen?

Good luck,

RE: Vessel wall temperature

OK for the capacity calcs for blow down/psv anyway in accordance with API (this is what hes asking for).

Since wetted area normally is 50% of vessel volume heat transfer through the unwetted part can normally be disregarded

Best regards

Morten

RE: Vessel wall temperature

Agreed, for the calc it doesn't come into play directly.  The OP should consider it if applicable though.

Good luck,
Latexman
