Hoop stress calculation for a Oval shaped pipe
Hoop stress calculation for a Oval shaped pipe
(OP)
Hi,
I'm designing a valve as per ASME Sec VIII div -1. To maximize the capacity I'm trying to make the inlet into Oval shape. But I'm not sure how to calculate the Hoop stress for a given internal pressure. Please see attached oval example.
Thank you in advance.

My motto: Learn something new every day
Also: There's usually a good reason why everyone does it that way

Please see attached file (this is the top view). Here the round inlet merges into the valve gallery. I want to merge the inlet smoothly into the gallery to minimize the flow losses. This merging is resulting in the oval cross section. I want calculate the wall thickness required at that region by calculation Hoop stress. But it seems I've to rely on FEA only.
Please let me know if know any other method.
Thank you
