Cannot provide a general statement unless more information is provided regarding process conditions. Will condensate be present or is this tank kept at elevated temperature for steam service only? Is the tank inside or outside and insulated?
392F, 160PSIG, 1.3#/HR Steam
Condensate will be drained with a float trap.
Vessel will be externally insulated.
Vessel itself will be carbon steel but separation internals will be 316L stainless.
The only issue would be attachment of the internals to the CS shell ID surface with dissimilar metal welds. Use Inconel (Ni-base) filler which is a better coefficient of linear expansion fit between CS and 316L SS.
