    Minimum Required Thickness of Cone at Small End

    SnTMan, I read the code again and you are right about the maximum allowable compressive stress. I read the UG-33(f) and based on the post on InFlames, I developed a small program (a Excel spreadsheet) to calculate the conical straight flange dimensions. I check the results against the program...

    Theoretical basis to calculate min req cone thickness at small end

    I have the COMPRESS build 6162. I calculated a pressure vessel with a transition. The vessel is under full vaccum at 100ºF. A reviewer of the report questioned the value for the minimum required thickness at small end used in the calculation of expression (4) of Appendix 1-8. What is the...

    Minimum Required Thickness of Cone at Small End

    The UG-33 addresses the calculation of critical pressure relative to buckling. The critical pressure is a function of the average diameter of cone. The Appendix 1-8 addresses the calculation of reinforcement of a cone to cylinder juncture under external pressure. ASME defines tr as the minimum...

    Minimum Required Thickness of Cone at Small End

    Unfortunately Appendix L-3.3 and Pressure Vessel Handbook - Eugene F. Megyes not address the calculation of the minimum required thickness at small end under external pressure. Regards acbdcl

    Minimum Required Thickness of Cone at Small End

    I need verify the effective area of reinforcement of a cone-to-cylinder junction at small end. The Code address the calculation of the minimum required thickness of a cone in UG-33(f), but I cannot find any procedure to calculate the minimu required thickness of cone at small end to be used in...

    Nozzle at vertex of a conical or toriconical head

    When a nozzle under internal pressure is put at a vertex of a conical or toriconical head is neck thickness calculate by UG-45 or only by UG-27 and 1-5 ? I didn't find any reference in ASME VIII-1 code. Regards, Acbdcl

    How to calculate head plastic buckling pressure during the hydro test

    Steve ECCS is European Convention for Constructional Steelwork and published the following document: - "Buckling of Steel Shells, European Recommendations", 1988. I need calcute the stress during hidro test for an ASME vessel. The formulas of ASME code (Addenda 2003), for...

    How to calculate head plastic buckling pressure during the hydro test

    I need a formula to calculate the plastic buckling pressure for a torispherical and an ellipsoidal heads. What is ECCS formula for this plastic buckling pressure ?

    How to calculate available area A5 in nozzles like Fig UG-40(g)?

    I need calculate a nozzle with a configuration similar to Fig UG-40(g) of ASME VIII Division 1. I need to known how to calculate area A5 using te given in figure UG-40(g). Area A5 is calculated as a rectangular area A5 = (Dp - d - 2tn)*te*fr4 ? Or Area A5 is calculated as a triangular area...
