    Bore diameter "B" Flange ASME B 16.5

    As I understood, the hub thickness shall be determined as a pipe under internal pressure (for example using the formula of ASME B31 oder ASME Section VIII). The material will be the flange material. I'am thankful if someone can tell me the meaning or the background of the equation...

    Bore diameter "B" Flange ASME B 16.5

    Hi, for high rating and/or large size flanges in ASME B 16.5 the bore diameter (Dimension B) is not specified in the dimensions tables. It's stated there that this is to be specified by the purchaser. My question is, how to specify this dimension such that the flange will "still" conform to the...

    UG-45 Minimum Nozzle Neck

    Hello, can some one explain the technical background behind the thicknesses tb1, tb2 and tb3 (Table UG-45). If the opening is adequately reinforced and the nozzle neck is checked for UG-22 loadings in determining ta thickness so for what are the thicknesses tb1, tb2 and tb3? Thank you Ali

    Gasket load at operating condition ASME VIII-1 Appendix 2

    I have another question more or less in the same field (gasket and bolted flanges etc..). Since I found your answers convincing, I want to post it again here: Hi, does any one have an explication for the expression of HG in 24-3 of Appendix 24, ASME VIII Div. 1? Actually I don't understand why...

    Gasket load at operating condition ASME VIII-1 Appendix 2

    Hi David, thank you for your answer. Actually Wm1 is only the minimum required bolt load at operating condition, in many cases you have to preload the bolt more than required by wm1, for example if wm2>wm1 and/or the available bolt area is larger than required by wm1 and/or by wm2. In those...

    Gasket load at operating condition ASME VIII-1 Appendix 2

    Hi, I would like to know your opinion about the expression of the gasket load at operating condition termed HG in the appendix 2 of ASME BPVC VIII-1. There, it is defined as Wm1-H=H+Hp-H=Hp, means the required gasket load at operating condition, only the required. The problem is that W can be...

    Clamp Connections ASME VIII-1 Appendix 24

    Hi, does any one have an explication for the expression of HG in 24-3 of Appendix 24, ASME VIII Div. 1? Actually I don't understand why the term Hp is being subtracted there, I expect only H to be subtracted as the gasket get unloaded by the force H as the pressure is applied (in analogy to the...

    Displacement Stress Range

    Hi Mohammed, this is simply the formula of the equivalent stress or stress intensity acc. to Tresca (shear stress theory). Here are just the moments considered, namely bending and torsional moments, stresses caused by direct forces are neglected, nevertheless you can add the longitudinal...

    beginner in Fortran77

    Hi, first i thank ev. body for support. I found out the problem, when i put format(3F10.3) which is equivalent to put format(F10.3,F10.3,F10.3) then the 3 variables have to be input in the same form as the Format so A,B,C together and then i have to press enter, when i put Format(F10.3) then i...

    Stress analysis

    hi every body, Reason of the Classification of stresses in the convential combinations given by ASME 31.3 as well as by EN 13480-3 for the comparison with the respective allowed material stresses . That combinations are the following : Stresses due to sustained and expansions loads Stresses...
