Calculation of the saddle for kettle-type reboilers
Thread Content
For kettle-type reboilers, sometimes the tube sheet is too long, requiring that one of the saddles be placed on the eccentric cone shell. How should such a saddle mounted on the cone shell be calculated? Has anyone encountered this situation? How did you handle it?
Why isn’t anyone participating? Have they not encountered this problem?
I don’t think there’s anything special about it; it’s just calculated using standard methods.
Is the calculation of the saddle at the cone done in the same way as for a regular cylinder? Is its circumferential stress the same as the normal stress?
No other input data for the saddle at the conical shell were visible; it’s no different from the normal case. The equipment design includes reinforcement for the conical shell, and when inputting the data, the software knows that the saddle is located on the conical shell, so this should be taken into account in the calculations.
How did you solve this problem? I’ve encountered it too
