This Fortissimo experiment addressed flanged joints that are used for high pressure and temperature gases or liquids. To seal the flanges a gasket is placed inside a groove which is located on both flanges. During the process of closing and tightening the joint, the gasket and the flanges may suffer deformations and high levels of stress which, if higher than the materials elastic limit, may damage the flange. This means that it cannot be reused, once it has been opened (e.g. for maintenance) or may result in sealing problems, leakages or a decrease in the joint’s operational life. Even worse, if the closing process is done inadequately, workers at the plant could suffer serious or fatal accidents accompanied by damage to the surrounding community and the environment. The results of the experiment are a model for simulating the tightening process and a front-end application to control the parametric simulations, which will permit improvements to the design of the tightening process.
