Hi,
Regarding Y3 (a)(pg.634)Q = Shear force between flange ring and end of hub, does the code prescribe an equation for this? or, is this simply basic shear force hand calculations?
Thanks in advance

Thanks, I'm not too sure to be honest the specification was pretty vague, simply asking to consider the mentioned loads. Our primary PV Engineer left us a couple of weeks ago so we are trying to figure out what we need to consider and how we go about applying such loads.
Obviously familiar...
Hi,
A customer has asked us to consider loadings of 4g in the X,Y & Z direction of a vessel supported on saddles.
Can anyone point me in the right direction with such a problem. Is this something that could be analysed by FEA or, am I over complicating the problem? Is this seismic/harmonic...
We have a requirement for a vacuum insulated pressure vessel. Therefore the pressure vessel will have an outer jacket. Is anybody familiar with the concept of including the provision for a device that prevents the collapse of the inner vessel. Can anybody point me to the clause (if one exists)...
Does anyone know how to determine allowable stress values for low temperatures. I need to know what ASME states for design temperature if I am designing a vessel for operation at -196°C. For example: I am using SA240 304. the allowable stress (ATM) = 206.9 MPa, Allowable stress (DT ((@-196°C)) = ???
Fantastic. Very helpful guys! I appreciate your input on this. As I said I'm trying to pick up these codes as the main ASME guy has now left our company so I've been thrown in the deep end! I'm sure I will be back on here very soon [ponder]
Brilliant, thanks Tom, that also makes sense. I've been over thinking the process. Therefore I'm assuming the factor of safety is somewhat built into to the data that has been tabulated.
Many Thanks!
Thanks, makes sense!
I'm just at a loss as to where the 3.5 safety factor comes into the whole process. For instance for 304 stainless it is 3.5/515 = 147.1.... OK that's great but what do I do with that figure. So then there is the room temperature figure overleaf that is 138mpa at room...
Many thanks for the reply! Much appreciated! I will certainly do this in the future.
However I'm still really struggling trying to interpret this. Basically I have some calculation data (done by an ex-employee) here which is for 304L stainless steel. He states that the allowable stress value is...
Hi There,
I'm very new to pressure vessel engineering especially ASME.
At the moment I am trying to understand where things come from and how they are applied, so please excuse me if me question sounds very amateurish .
With regards to the allowable stress values stated in ASME II Part D...
