Dear all,
I am working on one shell & tube heat exchanger (TEMA Type : BKM )
channel side is steam jacketed as per ASME Sec.VIII.Div.1 Appendix-9 Type-2 jacket.
Channel Shell MAEP is governing Jacket MAP.Client Specification requires hydrotest pressure as per UG-99(C).
If we multiply 1.3 * Inner shell MAEP than that component will fail.
Incase of internal hydrotest we can go for 0.9*Yield stress.
What about value of Compressice stress B from external pressure chart.Does code/specification permits this.
What to be done in this situation....Please share your views.
