Under internal pressure, a bellows can behave like a column under a compressive load. If pressure is too high, the bellows can buckle or "squirm." The EJMA Standard provides formulas to calculate the maximum safe pressure before two types of squirm occur:

If you are working with an authentic copy of the EJMA standard, you will find highly structured technical sections designed to streamline the engineering process: Section / Chapter Focus Area Engineering Utility Design Formulations

The Ninth Edition of the EJMA Standards was published in 2008 and represents a significant milestone in the development of expansion joint design principles. EJMA standards from this edition onward thoroughly covered the design of expansion joint bellows elements, providing detailed engineering data for metallic bellows expansion joints with specific convolution shapes and meridional direction welds. Under internal pressure, a bellows can behave like

If you have a specific edition, formula, or application (e.g., pressure, temperature, materials) you'd like to discuss, I can help you find relevant information from the EJMA guidelines.

EJMA outlines procedures for testing expansion joints to ensure they meet performance specifications. This includes pressure testing, cycle testing, and non-destructive testing. Key Editions and Revisions 10th Edition (Latest): If

Key design factors used in EJMA calculations include:

One of the most confusing aspects for searchers is the edition number. The EJMA updates its standard every 3–5 years.

The standard offers guidance on the materials used for expansion joints, including the types of metals and the fabrication processes. Material selection is crucial for ensuring compatibility with the fluids being handled and for withstanding the operating conditions.

Stress resulting from pressure pushing against the convolutions.
