Kazi,

Firstly, as I'm sure you know,
PVElite is not the tool to use for
ASME VIII Div 3. I have never used Division 3 so here ends my practical knowledge, however...
Secondly, I'm going to quote from the code itself -
"The Code is not a handbook and cannot replace education, experience, and the use of engineering judgment. The phrase engineering judgment refers to technical judgments made by knowledgeable designers experienced in the application of the Code." My apologies but your question suggests that you are not suitably "experienced". I would suggest that you or your organisation seek suitably experienced engineers to assist in this project. Otherwise you're at the wrong end of the learning curve which is no place to be if anything goes wrong.
Thirdly and out of curiosity I did a search on the ASME web site and found,
a) Your National University of Sciences & Technology in Rawalpindi looks like it may be able to offer assistance.
b) There is a publication (BOI - 2000 Criteria of the ASME Boiler and Pressure Vessel Code Section VIII, Division 3) which offers further explanation of the code. You can find it at,
BOI - 2000 Criteria of th...ision 3 Best of luck
