Dear moderator,
we are usually design the tubesheet according to ASME UHX and TEMA standard. The thicker thickness will be adopted. The thing is when you run it in PVelite, you just only have each module for each run. I'll suggest to make a check box for the user to choose whether he/she need both TEMA & ASME UHX Tubesheet reports in 1 run time.
Thanks

Dear KKchong,

Your suggestion is good but if you refer TEMA then as per new TEMA, its design rules are not mandatory and shall not be used over and above ASME Code...Hence many clients dont want TEMA tubesheet design. But I am also agreed that many clients ask for both the design together.

You suggestion of check box seems to be good so that with one run we can have both design together. One who wants both, can check the box. Let the moderator to feel whether this facility should be provided or not.

When designing new vessels to the ASME code, UHX is mandatory. However, in places like Germany where the AD Merkblatter code is used, that code does not consider thermal load, and as a consequence they often use the TEMA method as a backup.

With regard to having TEMA and UHX included in the same results file, there are complications. In the UHX method, the programme does a lot of iterations. These iterations could conflict with the TEMA method. Remember, the MAWP's are worked out in UHX, which would not apply in TEMA.

It is so easy to switch from UHX to TEMA and vice versa, that it is a click of the mouse is all that is needed to get comparison between the two codes.

i'm not saying to have TEMA tubesheet calc and ASME UHX calc in same 'result file' (sorry for misleading if i did) but if possible to have it in a same report. Its mean that you can have both calculation in a same report. It will maka our life easier that we need not run it in ASME UHX then rerun it with TEMA cal for compilation use. We have to make a calculation submission to our cliet as well.

Hello KK

The reasons I gave still stand.
