The use of bellows expansion joints is an effective measure for rationalizing various piping systems in industries. Essentially, bellows should be designed so as not to be subjected to torsional loads. Usually, the bellows is protected so as not to be twisted by the hardware. However, it is a fact that there are some sources of torsional deformation, e. g., the clearance of the bearing structure and the deformation of the hardware. Therefore, it will be useful to elucidate the allowable torsional displacement of bellows from the point of view of improvement of reliability in design and fabrication. In this paper the stress due to torsion and the torsional buckling behavior of bellows are investigated through both theoretical and numerical analyses. The numerical solutions agree with the theoretical results very well in a wide range of dimensions and the number of convolutions. Based on these results, the framework of the design rule related to the torsion of bellows is proposed.
