Half pipe jacketed vessel under external pressure

Half pipe jacketed vessel under external pressure

Half pipe jacketed vessel under external pressure

(OP)
I have to check if an existing vessel could be used under full vacuum.

It has a half pipe jacket in the shell and bottom. I think the jacket acts as a stiffener but it is not clear for me how to calculate it. I didn't find anything about that in ASME VIII.

Can anybody help me with that?

Thanks in advance.

RE: Half pipe jacketed vessel under external pressure

nalasoc2, if it is the vessel itself you are interested in you might start by ignoring the jacket and just calculate per UG-28 and so forth.

Regards,

Mike

Thanks but ignoring the half pipe jacket the shell is not able to work under vacuum.
I want to know if the half pipe jacket acting as a stiffener ring provides enough resistance.

RE: Half pipe jacketed vessel under external pressure

nalasoc2, in that case I would probably check that the jacket provides, above what is required for pressure, material that meets the area and moment of intertia requirements for stffeneing rings given in UG-29. If it is a helical arrangement it'll be a little messy, but perhaps do-able.

Regards,

Mike
