FEA Analysis for Tube Sheet

I believe TEMA would have a better design criteria for the Tube sheet

TEMA 9th edition has removed the tubesheet calculations from the standard. The TEMA method didn't stand up to rigorous stress analysis.

For the ASME world, Section VIII Div. 1, Part UHX and Section VIII Div. 2 Section 4.18 are identical to each other and represent rigorous analytical stress analysis. They evaluate against different stress criteria - Div 1 is based on allowable stress in tension and Div 2 is based on allowable stress intensity.

If you have a geometry that is within the scope of UHX or 4.18, FEA should give the same stresses.

If you have a different geometry, then FEA can be done by following the pattern shown in the Code sections. Pay attention to the reduced section properties for the tube field, the different load cases (7) and the allowable stresses. Pick either Div 1 or Div 2 allowable stresses based on the Code that the rest of the vessel is subject to.

Thank you for the update and corretion Lawrence.

Having design heat exchangers in the past. There was very little from ASME about this at that time.

And oddly enough having to ask our AI about it, that was the same response.

Thanks again,
