SnTMan, This is what I am searching. Can't find any guidelines about it in the code. Thanks for your input. At least you understood the question.

GD2, you need to read my question again. This is clearly not what I asked.

This is the last part of note G5 "For Section III applications, Table Y–2 lists multiplying factors that, when applied to the yield strength values shown in Table Y–1, will give allowable stress values that will result in lower levels of permanent strain." Now question is which multiplying...

G5 refers to table Y-2 for section III applications. In Table Y-2, there are factors for limiting permanent strain. Does it mean that if I want to limit the strain to let's say 0.1 %, then I will use factor 0.9? Does it mean that I can randomly select any permenant strain value without...

What is the reason that the low strength listing of SS304 is not permitted for section III? & What if there are issues with excessive expansion? Does it mean that we must take the high strength values even for flanges in section III? Please check line no. 13 and 14 for SA-240 304 in attached...

I am currently working on calculations for a wire wound cylinder following Young's and Brownell's approach. However, I've noticed that there are no specific calculations available for a wire wound yoke frame design. Additionally, even the ASME Section VIII Division III only provides stress...

We can actually buy this? It's new. Thanks

Hi, can anyone here share me the wire wound vessel problem from PTB-5 2019?

Thanks for your input every one. I will explore DesignCalcs and VVD now.

@MJCronin, Equipment will be installed in Pakistan and we'll be dealing with Section VIII Div 1 vessels and heat exchangers. & yes, software should be able to deal with seismic loads.We need a licensed software that could be an alternative to PV Elite.

We are looking for a good software which deals with pressure vessel and heat exchanger design calculations. Previously we have been using PV Elite which is really good but due to some license limitations we are looking for some other option. We will prefer one which doesn't require internet...

Anyone who came to this link looking for this topic, I will recommend to read asme criteria (at end of PTB-1) first and then example problem of elastic stress analysis in PTB-3 & PTB-5. IMO best source to understand the stress classification and criteria is " Design methods for power plant...

@ GD2, Thanks for your input. Can you share some free training material here? I don't think they can teach much in those 5 day DBA trainings.A good book on this topic can be better helpful, if there's any?

Thanks NRP99, I have read this post some time ago and it really is a good explanation. Do you agree with my reply to prex?

@TGS4, In my company they just use PV Elite and nobody is there to mentor me. I guess I have to try and learn by myself.

@prex. Let's consider nozzle in shell and shell head junction. If we apply sustained loadings from piping on nozzle and internal pressure and run the FEA simulation. We expect primary (to maintain equilibrium) and secondary (at nozzle shell interface due to geometric discontinuiy) both stresses...

You qoute this para many times already. :) My question is regarding separation of primary stresses from total stress field.If you don't want to answer my question that's fine.

how can I seperate primary stresses from total stress field?

In elastic stress analysis by ASME sec VIII div 2, please explain how can I seperate primary stresses from total stress field? Please suggest a good article or thread whatever might help.Thanks. @TGS4 and other experts are requested to please guide a newbie here.:)

1. yes. This is the first time I'm doing this work. 2. It is a distillation column of 110 ft height and it is skirt supported. I need to design the trunnions for lifting of the column during installation. I'm using PV elite 2018 and it doesn't have this option as far as I know. & yes, my boss...
