Vessel Rupture (Fire)

Vessel Rupture (Fire)

Vessel Rupture (Fire)

(OP)
Hello All,

I hope you can guide me on my way to find an answer. I need to calculate if a separator is going to rupture due to fire exposure. I estimated the temperature profile through time. I think I have to calculate the strength on the vessel to compare it with the UTS of carbon steel at those conditions but I don't know how to do it. Please could you ligth me on this?

Thanks in advance,
Petroleo

Petroleo;
You can simulate the rupture condition of the vessel by knowing the rupture strength of carbon steel, as a function of metal temperature and internal pressure.

The thickness required to sustain internal pressure at a specific temperature can be done using a simple hoop stress formula for starters, that would apply to either thin or thick-walled vessels.

metengr,

Have a star for a really interesting link

Petro....

You are in the wrong forum....Go to the "safety relief valve engineering" forum

There are articles and publications that were included in "Chemical Engineering Magazine" on this specific topic.

The article you may want was written by "Wing Y. Wong"--"Safer Relief Valve Sizing," Chemical Engineering, May 1989, p. 137.

He has written others....."Fires, Vessels and the Pressure Relief Valve", May 2000, pages 84-92

As a common courtesy that is practiced in the USA.....let us know what you final results are..

My opinion only..
