Numerical Analysis of the Damage in a Flanged Joint
Year: 2013
Type: article
Abstract: Flanged joints arefundamental components of pipelines and they must be optimized to avoid leaks,bolts overstress and flanged joints damage. Overcoming standards indications asover-torqueing, and combination of different parameters, as difference in hardnessbetween flanges and gasket, can cause groove impressions. Aim of this study isto provide an efficient tool to optimize the choice of characteristicparameters of flanged joints, by numerical simulations. Geometries of a realtest case are simulated by FE models, considering different values of flangeand gasket hardness, as well as tightening torques, in order to cover possibleranges. From the analyses, it is possible to highlight that a particularcombination of hardness difference and over-torque is responsible for permanentflange impression.
