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. WebDec 15, 2024 · With regards to calculating rotation of flange, the rigidity factor formula in ASME VIII Table 2-14 can be modified to do just this. By simply removing the K factor the result will be rotation in degrees. So in essence, ASME VIII rigidity limits rotation on integral flanges to 0.3 degrees and rotation on loose-type flanges to 0.2 degrees.
