mawp of tube sheet in fixed tube sheet type exchanger with thick expansion bellow
(OP)
hi to all,
can any body tell how PV elite canculate mawp of tubesheet with expansion bellow (with outer cylinder). in my design, stress in expansion bellow are with in limit (as per TEMA 8th edition) but when i am checking the mawp of tubesheet in summary of mawp calculation, the mawp of expansion bellow which pv elite calculating is less than design pressure (and there is no warning/error in pv elite) which in turn limiting the mawp of tubesheet. if stresses are with in limit, this means that design pressure is "at least" the mawp of tubesheet.
can any body help in this.
