We have designed exchanger with Div-2 Ed 2004 with ASME code stamp requirement. Since Div-2 does not give Tubesheet thickness calculations, we had performed calculations with Div-1 UHX which is conservative approach. But the PE is insisting to do FEA becuase Div-2 does not allow anywhere to use UHX. My question is
(1) Is the PE view correct?
(2) Why it is not accpetable though it is conservative? (3) Similarly can we use Tube-Tubesheet joint calculations as per UHX since these are not given in Div2. (But Ed 2007 Div.2 has provided these calculations same from 2004 Div.1)
If it is acceptable to use Div-1, Please tell me the relevant clause reference.
Eagerly waiting for your reply
