A well-designed bellows must be well-built. This section provides:
One of the most misunderstood aspects of expansion joints is their interaction with pipe supports. This section provides mandatory equations for the distance between pipe guides to prevent lateral buckling due to pressure thrust. Ejma Standard.pdf
Unlike generic piping codes (such as ASME B31.3), the EJMA Standard specifically addresses the unique behaviors of bellows: their flexibility, fatigue life, instability modes (column squirm, in-plane squirm, and torsional squirm), and cycle life under pressure and movement.

If you are working with the PDF specifically, pay close attention to and the Examples section at the end of the document. These sections provide the practical application of the theory and are invaluable for verification during the drafting and review process.
The EJMA (Expansion Joint Manufacturers Association) standard is a widely adopted industry guide for the design, fabrication, and installation of expansion joints in piping systems. It provides detailed guidelines for stress analysis, flexibility, and thermal expansion, helping engineers and designers ensure safe and efficient piping systems.
