It is my understanding that the reference to Code Case 2523 is no longet required when using differing systems of units as it is now addressed in the code itself - see Section U-4, 2006 Addenda - 2004 Edition of ASME BPVC VIII Div.1; also the case in the 2007 Edition.
One other important element to remember is that gussets impart out-of-plane loads on the vessel shell and in the main, shell structures do not cope well with out-of-plane loads particularly if the loads are of a dynamic nature (arising from agitatators or similar). There are two failure cases...
Take a look at "Tubular Steel Structures - Theory and Design" by M.S. Troitsky (published by the James F. Lincoln Arc Welding Foundation, Library of Congress Number - 81-80993)
In Annex C of PD 5500:2000 Symbol "m" is defined as "the index in equation of fatigue design curve (see table C.1)"
Formula C-5 is of the form "Sr^m * N = A" where:
Sr = Stress Range (N/sq.mm)
m = as noted above
N = is the design curve fatigue life (cycles)
A = is...
Agree with observations of the previous respondents. A very useful document (available as PDF downloadable) is the "Pressure Equipment - Guidance notes on the UK Regulations (URN 99/1147)" from the UK Department of Trade and Industry (www.dti.gov.uk/strd/strdpubs.htm#pressure) which is...
Just to thank the respondents on suggesting Kern (which I had looked at) and TEMA (which I had forgotten about not having been involved with S&T HE's for quite a while - Section T-4.32 being what I was looking for). Just for information, I was seeking to establish a mean metal temperature of the...
Require assistance in finding a straight forward routine to establish the metal temperature in the inner pipe of a double pipe heat exchanger. Outer pipe/jacket has the heating medium (in this case LP steam) and the inner pipe has the medium to be heated (in this case a hydrocarbon gas).
