Someone knows if UHX- tubesheet of ASME Code Division VIII-1 permits to use different inside diameters for channel and shell sides, having tubesheet integral (configuration a).

Thanks Enrique

Why not? Where is it prohibited? Mind the FOREWORD:

"This Code contains mandatory requirements, specific
prohibitions, and nonmandatory guidance for construction
activities. The Code does not address all aspects of these
activities and those aspects which are not specifically
addressed should not be considered prohibited....."
