Jacket Closing Ring UA - 104

[Clareok]

Hello,
I'm designing a conventional jacket to ASME VIII, Div 1 and want to calculate the jacket closing ring thinkness. I've looked at App 9-5 and i think this is the correct section to be looking.
I have checked a heat transfer book and this refers to Para UA-104 (ASME Code).

I cannot find this is Div 1, does anyone know where i should be looking?

regards
Nec

Why would you bother to find UA-104 when you are doing a mechanical design of a standard jacketed pressure vessel in accordance with ASME VIII Div 1, Appx 9? There is no ASME code paragraph identified as UA-104, perhaps it is a printing error or reading error.
Cheers,

Way back a long time ago, Sec VIII, Div 1 paragraphs were designated UA-whatever. I am talking A LONG TIME ago.

Clareok, you are correct about Appendix 9, I don't know how you might match up the UA-104 reference to Appendix 9.

Regards,

Mike

Geez, SnTMan, I'm happy that I'm not old enough to remember that...but you memory is still good!

gr2vessels, you misunderstand, but thanks for the compliment. I can still remember everything I haven't forgotten

I have not been in the business long enough to have experienced the UA- times directly, but you see it in older references (and they are pretty much ALL older) such as Taylor Forge Bulletin 502 for example, and the OP's book obviously.

I have actually seen, once, a Sec VIII, Div 1 that would fit in your back pocket. The whole thing.

Regards,

Mike
