HI
I NEED TO TALK ME WHICH SOLUTION IS BETTER?
TEMA OR ASME STANDARD FOR ESTIMATE THICKNESS TUBESHEET?

Method provided by ASME is more accurate but method of TEMA is requires less calculation work. Usually (?) method of ASME gives thinner (and cheaper) tubesheets.

Because of very high steel prices, I would recommend you to calculate tubesheet thickness as accurate as possible using method of ASME. Saving time in calculation of tubesheet thickness is wasting of money!
