Pressure Vessel Code Book
Pressure Vessel Code Book
(OP)
I'm a pipe stress engineer, but I often have to deal with stresses on nozzles, clips, et cetera. I am not up-to-date on the latest ASME BPVC Section VIII. I have access to the code itself, but I don't know if reading hundreds of pages is the best use of my time when I am not in the business of designing pressure vessels. What I mainly want to know is how the latest edition of the code calculates stress and determines allowables and what are the various code cases. Can anyone recommend a good reference book?

Code Cases are a different matter and are associated with specific code book sections.

I have never been able to get my head around WRC 107, but PD 5500 Appendix G is similar and has some good expanations of the theory and examples showing what the calculations do.
ASME VIII Div 2 Part 5 gives you the procedure to for FEA but you learn little in the way of back ground theory or explanations. You have to already be competant at FEA to fully understand it.

Good for casual nozzle evaluation... covers WRC 107/297

Stay away from a do-it-yourself FEA (or worse, a black-box FEA) until you understand all of the above. Otherwise, you're more dangerous than not, because you think you know what you're doing, and you really don't.

What I'm trying to do now is to learn all about how the BPV calculates stresses and what exactly all the code cases mean. When I use Caesar II, I know exactly what's going on under the hood and could reproduce the stress calculations by hand. I don't have that level of understanding with BPV code calculations.

Can you be more specific? I have access to every edition of the code back to 1989. Is there something that is called, "Criteria Document" or is it contained in a part or appendix?

Your point is well taken...don't use the tool unless you understand it's development. Must understand the development...Can't argue with that.
But I did use the word "consider"...
If you are evaluating a few nozzles per year....stick with the source documents.
If your MBA boss has contracted for the analysis of hundreds of systems, with even more nozzles than systems.....and he wants to use a rectal thermometer to recruit people off the street to "help" you
...and its all due in les than a month.
Automated tools start to look pretty good.

what edution are looking for:
MWK-1941 Kellog's "Design of Piping Systems".??
MKW-1956 Kellog's "Design of Piping Systems".??

RE: Pressure Vessel Code Book
Which edution of Kellog's "Design of Piping Systems" did you have??
RE: Pressure Vessel Code Book
Can you clarify what an edution is??
RE: Pressure Vessel Code Book
I heard couple of times about Kellogg's Piping Design Handbook. I asked other people but nobody knows about it. Can anyone explain me what is this magic book and where can I get a copy of it?
Thank you,

I would like to know your opinion about the following book:
Introduction to Pipe Stress Analysis by Sam Kannappan. If I'm buying Peng's book with Kelloggs book does it worth to spent $70 to buy Pipe Stress Analysis by Sam Kannappan.
Thank you,
Curtis

Just buy Peng's book. It's got practically everything you need.

Thank you saving me $100.
