    WRC-537 Calculation

    Hi all, Do we need to include weld-leg size in calculating 'c1' & 'c2' values (rectangular attachment)? If I have a rectangular attachment of L=5" and W=3" with a weld-leg size of 0.25". Which one is correct below? Method-A: c1 = 3/2 = 1.5" c2 = 5/2 = 2.5" Method-B: c1 = 3/2 + 0.25 = 1.75" c2...

    ASME Section-VIII Div-1 Appendix-1-4(d) Tori-spherical head calculation

    Appendix 1-4(d) has, L_o = outside spherical or crown radius [which is for OD calculation basis] Many other components use outside diameter or radius value of new condition even if external corrosion is applied. While I found the COMPRESS app is using the corroded value of L_o in OD basis...

    Buckling Analysis of Assembly

    I am in need of help regarding the bucking analysis of an assembly. I want to get the buckling load factor of individual parts from the buckling simulation of the whole assembly. Can anybody tell me if that feature is available or not? Please, explain if this is possible.

    Saddle bolt distance from center-plane of saddle.

    Does the location of bolt in saddles impacts the design of saddle (i.e, if I move the bolts symmetrically far away form the saddle center-plane, that goes through the axis of vessel). More likely, I am in need to keep 2-bolts-per-saddle on each end of saddle, inline with web plate. On selecting...

    ASME Section-II Part D, Table: TM-1 (modulus of elasticity)

    I need help in using Table TM-1 (ASME Section-II, Part D). I couldn't find a way to know the carbon content of CARBON STEELS. As first two rows of the tables are governed by carbon percentage, I stuck on how to select a correct row while selecting a CS (carbon steel) material. For example: When...

    API-650__Seismic Calculation__(E.6.1.4 Dynamic Liquid Hoop Forces)

    In Annex E section E.6.1.4 (Dynamic Liquid Hoop Forces), how do we calculate the value of Y? (Here, Y = Distance from the liquid surface to analysis point, (positive down), unit: m (ft)). I don't know how to find out the 'analysis point'. Can anyone please help me with this?

    API 650 5.10.5.2

    Thank you guys for your replies. Also, I would like to ask you that if we calculated the minimum participating area from section 5.10.5.2, then we shall not use F.5 to find out the minimum compression area?

    API 650 5.10.5.2

    Can anyone please tell me about the formula given in 5.10.5.2? Is this formula given to calculate compression area at roof to shell junction or it is the formula to calculate corroded thickness of shell?

    Wind code

    Pv elite has two reports one at the design summary is calculated as u said. but the one you have stated here at the wind and earthquake load section is a bit confusing. Don't know which moment they have calculated. Maybe you should look into the forums of Pv elite.

    PV Elite (nozzle joint efficiency)

    Thank you CuMo, but i am still not clear about my question... I went through the code book of ASME VIII-1 with many paragraphs/codes regarding this issue but still not satisfied with explanations there and i particularly want to know how should we handle nozzle joint efficiency (flange to neck...

    PV Elite (nozzle joint efficiency)

    I am using PV Elite 2017 with code reference ASME Sec VIII, Div-1 for Pressure Vessel Design. now i have a issue with nozzle joint efficiency. I need to know how the system acquires nozzle joint efficiency, or the input tabs for it. I have input longitudinal and circumferential seam efficiencies...
