Revised design calculations have been uploaded. Reply on your comments is as follows. 1. We are taking the properties of non-asbestos gasket in the calculation.
2. Yes, we considered the design pressure with static head.
3. We corrected the bolt spacing in revised calculation. 
4. As per the UHX 13.5.11 design is reconsidered by using elastic plastic calculation define in UHX 13.7,
     In step 11 you found shell stresses are within the limit.
5. We should indicate that we have not considered TEMA for the design of FFE.  We are following only ASME Section VIII, Div. I.  This was clearly indicated in our G.A. drawing which was submitted before order and we are carrying out the design and fabrication exactly as per the G.A. drawing.  Hence TEMA is not applicable.
6. We attached herewith file of PV-elite design input & design output result.
