ASME VIII Div 1, No Nozzle, Reinforcement calcs?!
ASME VIII Div 1, No Nozzle, Reinforcement calcs?!
(OP)
Hi All
I'm designing a pressure vessel to ASME VIII Div 1 and
basically the shell has not got a nozzle. Its Ellipsoidal
dished ends with an 89mm hole machined out of one end and
50mm out of the other end. Does it need reinforcement and if so:
How would I calculate this?
Would I set tn as zero in the equation in UG-37?
The vessel isn't subject to Rapid Pressure Fluctuations!

RE: ASME VIII Div 1, No Nozzle, Reinforcement calcs?!
the code says ""openining"" must be checked for adequate reinforcement.
how do you hydrotest this vessel with open holes
RE: ASME VIII Div 1, No Nozzle, Reinforcement calcs?!
fits into the larger end and a flanged connection slots into
the smaller end from inside (before the larger end is sealed), both are bolted from the outside with large
nuts. As a bladder accumulator.
Hydrotesting is done with this arrangement in place.

Otherwise, perform calculations per UG-37, with all quantities related to a connection set to zero. Your only available reinforcement will be the excess thickness in the heads.
