Urgent TIP on torispherical head to be transported into two halves
Urgent TIP on torispherical head to be transported into two halves
(OP)
I have a question that's puzzling me this evening, and any hint would be really appreciated.
I am dealing with a torispherical head that has to be delivered into two halves, for transport issues.
In attachment you can see the geometry, and consider that it will be manufactured from plate, A516 gr60N.
The idea is to cut it along its diameter AFTER forming.
Consider that this head will not be welded on a real ASME "pressure equipment" (design pressure is 0.6 barg, Temp is 350°C).
I was wandering about what may happen when we cut a head like this after formation. Should we expect to observe free deformation due to some stress concentration that the head has suffered during forming?
Will the two halves edges not correspond when they will have to be re-welded on site?
Honestly, I can't predict what's going to happen.
Any help will be highly appreciated.
Thanks!

you can make a cradle to mount the head standing on edge but leaning to one side to keep the height and width down
that's what i would do to keep from cutting the head and trying to reweld it.

But what about the deformation after cutting?

I doubt anybody can say for sure what it will do when you cut it.

and hope for the best . you are lucky
for pressure you would have to RT

then Radiographed and MT.
at this point they are normalized.
then formed in one piece.
It's been a while since i have seen a head fabricated in sections and then welded,,except for extremely large heads
