Plate Heat Exchanger Design

[Fizza453]

Good Morning.
How to calculate the required thickness of heat transfer plates in Plate Heat Exchangers (PHE) as per Section VIII Division 1?
I can see only in API 662 that minimum thickness for plate elements shall be 0.5 mm. UG-16 excludes PHE from minimum thickness requirements.

Is it a U-2 (g) case?

I found the Code Case 2766, it does not require any design calculations or proof testing for establishing the MAWP for gasketed plate packs provided all 6 conditions of CC2766 are met. MAWP of other pressure retaining parts will govern the design. CC 2766 is not covering fully brazed or fully welded plate packs.
I came to know from some friends that Edition 2017 of ASME Section VIII-1 will bring Appendix XX dedicated for PHE, is it correct? any comment?

Secondly any idea, how to establish MAWP for fully brazed or fully welded plate packs

Yes, that is correct, as well as the NBIC.
