Rectangular Flat Face Flange with Metal to Metal Contact Outside Bolt Circle

[wsmith22]

In order to size the bolts for this type of flange, the contact force between the flanges is required. Since this is a non-standard rectangular flange, the calculation methods in Appendix Y are not applicable. Once the bolting is determined, I will run an FEA. Can anyone provide some insight in how to go about determining Hc?

Thank you

Rectangular Flanges Calculation - Boiler and Pressure Vessel engineering

Hi, I need to calculate an air coolers headers acc. to ASME. I'm using appendix 13 for boxes, but I need to calculate rectangular bolted cover. I have found one thread here posted in 2002 saying that I should use UG-34 and bolt load to calculate acc. APP-2 (for circular flanges). My question...

Have you checked Enquiry Case 5500/133 to PD5500 for rectangular flanges?

Thank you. Looks like the rectangular flange with full face gasket procedure can be modified to work.

I once read an article regarding design of bolted flange connection for non-circular pressure vessels.

Try to google it.

Enquiry Case 5500/133 is OBSOLETE.
See PD-5500 (2021)

Attached you could find a document related to design of non circular openings.

@ Pengar

This is not applicable. The original author is talking about flat-faced metal-to-metal contact.
