Axial Nozzle offset in elliptical heads
Axial Nozzle offset in elliptical heads
(OP)
My question is related to axial nozzle offsets in elliptical heads for heat exchangers. A senior engineer at work told me you cannot offset a nozzle by more that 80% of the shell diameter. Anyone heard of a similar rule. I would like to read/learn more about it.
Thanks in advance.
Thanks in advance.

There is however no prohibition of putting the opening outside that circle.

What, exactly, is meant by an "axial nozzle offset" ?
How do you measure or dimension this ?
RE: Axial Nozzle offset in elliptical heads
It is your practice to use the minimum head thickness per UG-32(d) in your reinforcement calculations, rather than the thickness of a sphere as per UG-37? Nobody kicks about it?
Anybody else use this technique? It would be very useful.
Thanks in advance.
MJCronin, it is a nozzle with its axis aligned with the vessel long axis and parallel to it, off centerline.
