    ASME BPVC Section VIII, Division 2 - Design by analysis of welded joints

    Hello, If a pressure vessel is to be designed by analysis and if the designer intends to validate the dimensions/geometry of the welded joints he specified without resorting to Part 4 for welded joint details, what steps should the designer take in order to analyse the weld joint? For instance...

    ASME BPVC Section VIII, Division 2 - Minimum distance between welded joints

    Hello, I would like to ask for your help in understanding the requirements for a correct welded joint design according to ASME BPVC Section VIII, Division 2. Specifically I would like to ask if the code states what should be minimum distance between the axis of a category D joint and the axis...

    Interpretation of a true position geometric tolerance

    Belanger and pmarc, Thank you both for your time and great answers. Your answers sparked a few further questions, if you don't mind: - In the attached drawing what is the length of the theoretical cylinder that contains the axis of the pocket with diameter DIM A: is it the length of the...

    Interpretation of a true position geometric tolerance

    pylfrm, Thank you, that makes sense. I have one final question: do datum feature A and datum feature C define the top and bottom, respectively, of the theoretical cylinder that contains the axis of the pocket? I.e.: is the attached drawing correct (where the green axis represents the axis of...

    Interpretation of a true position geometric tolerance

    Hello, I would like to ask for your help in interpreting the true position geometric tolerance of the attached drawing. I believe it specifies that the axis of the pocket with diameter DIM A should be contained inside a cylinder with diameter 0.3 and whose axis: - is perpendicular to the face...
