Searching for a code if any (vessel)
(OP)
Hey guys...I have a vessel that contains a solution of a flammable liquid diluited in water (ammonia like) at atmospheric temperature and pressure. The vessel capacity is less than 0.5m3. The vessel doesn't have a nitrogen blanket. Vapor outlet is connected to a hood w/ extractor. Is possible not to apply ASME VIII Div 1? Is any other code or normative that I could apply? (ANSI, API, BS, etc)
Thanks in advance!
Thanks in advance!

You probably just need to design to a local standard or perhaps look at this thread http://www.eng-tips.com/viewthread.cfm?qid=377874 for some ides.
At 0.5 m3 this is a small horizontal cylindrical tank.
Supersonic - Check what the design pressure / MAWP is for this tank. Anything below 15 psig should mean it's a tank not a pressure vessel - the hint is in the name....

I have a mechanical engineer friend of mine that suggested to use ASME IX (only for the welds).
Design pressure is 3 bar. An inlet connection receives liquid from the recirculation of a positive displacement pump.

If you don't want to go down that route then you are really looking at a Pressure Vessel code of some sort. You might have got away with a design pressure of less than 1 barg, but 3 is too high.

At [up to] 1 bar, it is a 'tank' and you can use API-620, UL-142, API-12F [very low psi]

It states what Duwe6 said in the previous post.
