Thanks Marty007,
Ya its not from day 1, they just commented during the review of the drawings and design calculation....
Thanks all for your explanation. In my case governing is internal pressure for the top section.
Any how to avoid this condition what i did is , i just considered the Joint...
Marty007,
If i want to, i wouldn't do as we are in very much advance stages of engineering (We just got the comment from client)... all material had been procured and fabrication is already started .... if i vl design as u said at 8.9 kg/ cm2 (g) component having MAWP of 8.5 kg/cm2 (g) vl never...
Bikas,
I just want to ask you one question..... if your MAWP is limited by 8.5 ... can you go beyond that pressure for equipment in any condition ???
one more question to you.... suppose as u said ... lets assume that in any condition ... pressure at the bottom is 8.9 ... r you sure that at...
Bikas,
I assumed that what ever you want to say is right, than in the actual operating condition i can not go beyond my MAWP for entire equipment!!! ... in this case it is less than the design pressure of btm section...!!! in that case there is no use of extra pressure for the btm section and...
You mean, i have to consider the MAWP at least equal to the design pressure of Lower section ( pressure 8.2 kg/cm2 (g))...
but neither PV Elite nor Compress gives deficiency / failure report for this type of multipal pressure in the same chamber..
Mr Duwe6,
In our case...There is a single chamber, in top of the section, design pressure is 7.8 kg/cm2 (g) and at bottom section, design pressure is 8.2 kg/cm2 (g)... and the governing MAWP is 8.1 kg/cm2 (g) which is governed by shell of the top section... but as per definition of MAWP, MAWP...
