Dear member I'm going to design a fix tube sheet for NET type heat exchanger that has different shell and channel ID . shell Id is 2870 mm and channel ID is 2050 mm . is there any special requirement for design this tube sheet ? is it according to ASME sec VIII-Div 1 part UHX . another special...

ASME section VIII requires the sum of the principal stresses. I would like a plot of the sum of the principal stresses at every node. I need to find the node that has the maximum sum of the principal stresses. Can I do this in workbench somehow?

thanks for your kind answer . actually I'm not expert in elastic - plastic analysis . ASME SEC 8 DIV2 2015 5.3.1.2 Two analysis methodologies are provided for evaluating protection against local failure under applied design loads.When protection against plastic collapse is satisfied by the...

dear member I'm going to design a FSE (thick wall expansion joint) and a nozzle to shell junction by ASME SEC VIII DIV 2 . in addition to an elastic analysis (PROTECTION AGAINST PLASTIC COLLAPSE)our client asked to check PROTECTION AGAINST LOCAL FAILURE,but I found that principals stress to be...

is there anyone who can help?

I'd like to design a fix tube sheet according to ASME sec 8 div 2 - part 5 and evaluate stress in tube sheet and it’s connection to shell and channel but I don’t know how to define boundary condition according to code while there is an expansion joint in shell side (please see Fig 5.E.3 – ASME...

I agree with you ,but if we do it there will be sth. about 25% increase in thk. of flange. so we as a manufacturer prefer to ignore this calc. but our client persist on that and i am going to find some reason to convince them . Thanks

Dear Mike as I find Aspen B-jac check rigidity for this flange but in pvelite there isn't any calc. for it

Hi all Is it mandatory to check rigidity for floating head flange ( fig 1-6 d ) which designed according to ASME sec8 div1 app 1-6 equation 10? Thanks

thank you According to calculation of backing ring (that is really like test flange)for s type heat exchanger in pvelit (and TEMA RCB4.141)it seems that when we get the load from pressurized side(design p or any) the only things that remain is to follow the rules of Appendix 2. It is the fact...

Is there any one who have calculation test flange that approved by ASME authorized person?

thank you very much dear Mike figure E-4.13-1 of TEMA left hand is the type of test flange i have to design. as i check in 2-5(a)(2) it says "after the loads for the most severe conditions are determined, calculations shall be made for each flange following the rules of Appendix 2" therefor now...

I should design a flange as a test flange for testing tube leakage (shell side is pressurized ,figure E-4.13-1 of tema).I design it according to ASME appendix 2 with P=0 bar and W= MAX (wm1 (H+Hp) from mating flange in test pressure condition, wm2, 0.5*(Am+Ab)*Sa)) therefore Mo=0 and Mo' =...
