Flange rigidity factor
WebNov 24, 2003 · One of the reasons (and there are several) that it is conservative is that the gross bending moment on a flange is not actually equivalent to an axial load. The torsional rigidity of the flange acts to distribute the bending load around the flange. WebAug 3, 2024 · Abstract. A flange connection consists of the flange, gasket, bolts, and pipe. In a flange design stage, the flange rigidity index is checked to ensure the leak …

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. WebFeb 18, 2024 · These theories require adequate end post rigidity or flange rigidity to support the tension field or rotated stress field. But, in case of inadequate end post or flange rigidity the postbuckling strength in the end panels is either ignored or significantly reduced.
