Evaluating the flange rigidity for large diameter integral body flanges: index J versus the k-factor approach
Friday, May 15, 2020
Flange rigidity approaches intend to limit flange rotation in order to prevent leakage. Recently, Walther Stikvoort has published an article in which he evaluates various flange rigidity approaches for large-diameter body flanges. He concludes that the k-factor approach excessively compensates when compared to the index J approach which leads to a larger flange thickness and a less economical flange design.
