WebAug 17, 2005 · APPENDIX S tries to give more insight by adding the flange rigidity factor J. So to summarize : If your project requirement requires the use of Equivalent pressure approach and your equivalent pressure computation shows that the value is less than that permitted by B16.5/16.47 , It is ok but not a guarantee for a leakage no leakage situation. WebShort answer: make it thicker. Long answer: The moment of inertia affects the beam's ability to resist flexing. Use one of the many, free, online moment of inertia calculators (like this …
WebFlange Design.... STEP 1: - Calculation of required bolt loads Calculation of required Bolt load for operating condition = Wm1 H = total hydrostatic end force. Hp = total joint‐contact surface compression load G = diameter at location of gasket load reaction.
WebThe rules apply specifically to the design of bolted flange connections with gaskets that are entirely within the circle enclosed by the bolt holes and with no contact outside this circle, and are to be used in conjunction with the applicable requirements in Subsections A, B, and C of this Division. WebFlange Leakage Checking by Pressure Equivalent Method In this method, the axial force (F) and bending moment (M) on the flange are converted into equivalent pressure (Pe) …
WebAssuming flange stiffness is same as the pipe is technically incorrect because a flange is more rigid than pipe. However, it does NOT affect analysis results to any significant extent. You can choose to model a flange as a single point or take into consideration the actual flange hub length.
