Deflection on a Torispherical Head Due to a Concentrated Load

Not my field, but I believe odd shapes are usually solved by Finite Element Analysis software.

Thanks for the suggestion. Yes, it is possible to do with FE softwares like FE/Pipe. However, I am looking for manual calculation methods or any references in ASME / BS Codes.

Should be in here someplace...

Thank you, I will check for this.

You may be able to find something in a calculation of the effects of a supporting leg on a pressure vessel. However, placing supports on the PV head is a little unusual.

I would get someone who is experienced with FEA of pressure vessels to perform a calculation for you.

I agree with the comments above ....

Thanks for the suggestion. I will check for the above on Process Equipment Design/ PV Handbook.

The presumption is that the vessel is oriented horizontally?

What is the material of the vessel?Steel,Aluminum,other?

Is the vessel to be pressurized?

If so,do the pressures vary with temperature or other variables?

How long is the vessel,and what will be it's operating medium:Liquid,water;specific gravity.Is the base of the vessel level or sloped.If sloped,which end will be the loaded end?

What is the thickness of the vessel?

So many variables to the question it is not possible for me to give an educated guess at the answer.

With a pressure inside the <...pressure vessel...> above ambient, the action of <...a concentrated load...300lbs...> on it may well cause less <...deflection...> in the <...torispherical or ellipsoidal head...> than were the pressure inside it to be at ambient. For that reason an analysis may well be difficult to find as the <...pressure vessel...> needs to maintain integrity under pressure were that <...load...300lbs...> not applied, and will satisfy this criterion during insurance-witnessed hydraulic test. The Engineer/Surveyor for the company that is providing burst/collapse indemnity insurance cover on the equipment will therefore be a good source of information, for this sort of individual will likely have met this particular feature many times before, and will need to be satisfied during the witnessing of the hydraulic testing before insurance cover is applied to it ready for service.

Can the <...concentrated load...300lbs...> not be supported on something else, so that no load is being brought to bear upon the <...torispherical or ellipsoidal head...>, such as a nearby piping support? If not, then the <...concentrated load...300lbs...> needs to be considered as part of the structure of the <...pressure vessel...>, and needs to be included on the "for approval" issue of the drawings of this <...pressure vessel...> before construction begins, making it a one-off. The Engineer/Surveyor for the company that is providing burst/collapse indemnity insurance cover on the equipment still needs to become involved at an early opportunity, and prior to construction commencing.

Telephone?

The load case is similar to above. The E modulus of the material indicates its a plastic material. However I don't have any references as to the equations used.
