    APPENDIX 41 - Flange Calculation - Bolts strength question

    I enjoy everyone's cool responses. But you're right. If you think about whether a flange or a bolt will cause a fatal loss when it breaks, it's the flange. At least four or more bolts can be attached to the flange, but if one bolt is damaged by excessive tightening, the flange can be fastened if...

    Nondestructive Examination of ASME B16.5 Flange (Standard)

    allowable stresses in asme 2

    Mismatch of Grade and Unit at Material Test Report / ASME

    Hello all, When I checked the Material Test Report (MTR) of the material (SA-515) owned by the inventory manufacturer, there was no M in the grade notation. However, all records are in SI units. Is this mismatch allowed as ASME Code? Can I use it for a pressure vessel? Your help will be much...

    2021 Section VIII, Div. 1 Mandatory Appendix 47

    May I come in? My company is planning a Joint Review soon next year. I'm impatient because the new version has been applied soon. And I will talk to AI soon. Until now, in ASME VIII-2, it was necessary to obtain approval from a Registered Professional Engineer after performing analysis of Para...
