Appendix 13 - other code for circular section with central dividing pl

[tigny]

Hi,

Does anyone know of other code or method to assess the stresses in vessels of circular cross section with central dividing plate [with differential pressure]:

References useful for this, as I know, are:

* ASME VIII division 1, appendix 13;

* TEMA code (RCB-9-13);

* Roark & Young, chapter 10.10, tables 26 8a et 26 9 Bending of uniform-thickness plates with straight boundaries

Any other clues?

Yours truly,

tigny

Hi,

I'm still working this subject, and request some help.

[li]In chapter 13-4 of Appendix 13 (ASME VIII section 1), it is stated that ...The joint efficiency factor E shall also be
applied to the allowable design stress for evaluation of the
calculated bending stress Sb at the location of the joint
only. See 13-l(d), 13-5 footnote 1, and 13-8(b).

Does this mean that bending stress shall be compared to allowable SE?
So far I thought only membrane + bending should be compared to the allowable, in general 1.5SE

Please find a link to my file.

[li]An other question on the same subject,
what category would you apply to the welds of central dividing plate?

Category C: any welded joint connecting one side
plate3 to another side plate of a flat-sided vessel. (typography is not clear in the code; does it lack some comas?)
Category D: Category D. Welded joints connecting communicating chambers [...] to flat sided vessels[/li]

Yours,
