The (published by the Expansion Joint Manufacturers Association) is the global authority for the design, selection, and application of metallic bellows expansion joints . Since its inception in 1955, these standards have evolved to incorporate decades of engineering research and manufacturing expertise, ensuring safety in piping and vessel installations. Core Purpose and Scope

The Expansion Joint Manufacturers Association (EJMA) standard provides rigorous, globally recognized guidelines for designing, manufacturing, and applying metallic bellows, crucial for ensuring the structural integrity of piping systems against pressure-induced stresses and fatigue [1]. The standard, frequently referenced as "EJMA Standard.pdf," outlines key formulas for evaluating convolution geometry, ensuring pressure capacity, and preventing structural instability such as column or in-plane squirm [1]. Key design aspects involve analyzing hoop and meridional stresses, calculating fatigue cycles for single- or multi-ply bellows, and enforcing strict guidelines for surrounding piping anchors and guides [1].

Furthermore, EJM welcomes interdisciplinary contributions, including those on biomineralogy, environmental, applied, and technical mineralogy. Papers in any related field, including cultural heritage, are also considered.
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.
