Pressure vessel connection
Pressure vessel connection
(OP)
Hi everyone
I have a question that
design code: ASME sec VIII-1
In body of pressure vessel, we have made connection of NPS3, later off it was decided to change the connection to NPS2.
there is an option to use reducer of 3" x 2".
Question:
is it possible to blind the connection, and drill for NPS 2 again at same place.
if yes, any reference in code
