EJMA vs ASME Expansion Joint Standards | MechFlex Bellows, 17/10/2026
[…] EJMA (Expansion Joint Manufacturers Association) is narrower and more specific: its standard covers the bellows element itself — how to calculate spring rate, fatigue life in cycles, pressure capacity, and squirm/instability limits for a corrugated metal bellows undergoing repeated flexing. It doesn’t set piping system-wide stress allowables the way ASME does; it’s the engineering method for the one component that flexes. […]
