Mechanisms¶
- Bellows Joint or Expansion Loop
- Its central failure mode is that the flex itself becomes the fatigue-prone part: every cycle works the convolutions, so an element sized for movement but not for cycles can crack from low-cycle fatigue long before the straight pipe ever would.
This sourceExplains that repeated bellows deflection cycles strain the convolutions and determine cycle life, with fatigue cracking occurring when the cyclic movement exceeds the element’s design life.

Verification¶
Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.
Does it back the claim? Not recorded. The single citation of this work carries no recorded support check.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
