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. WebSingla noted several strategies and design adaptations that may be beneficial in these cases: Increasing the thickness of the flange and tubesheet. Reduce the allowable flange rigidity index. Reduce the allowable stresses for flanges and tubesheets. Make the required bolt ratio 120 percent of design and perform full bolt-load calculations.
