Hi,
I am trying to decide what loading should be applied in base state and perturbation state while performing an linear buckling analysis as per Type 1 ASME Div 2. I understand that the base state represents the initial pre-load. My understanding is that if we are checking for a load...
Hi,
I am working on a bundled offshore pipeline. One of the pipeline in the bundle is a "water winning" line. Can anybody please explain what is a water winning line. The only info I could get on that so far is that it is used for hydrotest. however, I am unsure how the hydrotest would work with...
All,
Does anybody have recommendation for free API 579 Fitness for service software or excel calculation sheets that can be downloaded.
Thanks in advance.
Hello all,
I am trying check a pressure vessel for plastic collapse and am using the elastic-plastic method. The load combinations are given in Table 5.5. The load combinations want us to add scaling factors. I am able to scale all loads without much trouble except temperature. What would e the...
Thanks TGS4,
For Option 3. It says to explicitly consider the imperfections. Can you please give some insight into what exactly are these imperfections? Are they talking about manufacturing imperfections or imperfections induced by loads? I am planning to load up the model with the nozzle loads...
Hi,
I am performing buckling analysis of a vessel according to Part 5.4. The design load factor to be achieved is calculated from a capacity reduction factor. I am specifically looking at ellipsoidal head. The capacity reduction factor mentioned in the section 5.4.1.3 is only for ellipsoidal...
Hi,
The question is about attachment welds on the pressure boundaries. In lay-man terms I understand the pressure boundaries as the metal surface responsible for keeping the pressurized media contained. I also understand that the welded attachments on the outer surface of the pressure boundaries...
Hi,
I am looking for a standard which gives some guidelines on how best to shape the termination of a doubler/fishplate plate to have low stress concentration at the ends. Any guidelines on overall design of the doubler will be helpful too. I deal with mining industry and design mobile mining...
I have a Masters Degree in Mechanical Engineering. I am working for the Industrial Gas turbine industry. My expertise is casings design under high temperature high pressure conditions. Gas turbine casing is assumed to be a pressure vessel from a design point of view. So I use Section VIII and...
Hi,
This maybe a vague question but any input on this is greatly appreciated. What would be a good stratergy on going about to look for jobs related to ASME Section VIII. Is there some online directory dedicated to B&PV industry?
Thanks in advance.
