Bellows unlike springs, in most of their deflections produce bending stresses in excess of the materials' yield strength. Understanding the performance characteristics and capabilities of various metal alloys in this "plastic" deformation region requires years of design experience and testing. Because of the unique challenges faced when designing an expansion bellow it is critical that the joint be designed and manufactured by someone who has the engineering and practical experience to design an expansion joint that will perform as required.

The primary function of a bellows expansion joint is to absorb the thermal expansion or contraction of a pipeline while, at the same time, containing the flowing media and withstanding the design temperature and pressure. This is achieved through the flexibility that is designed into the bellows expansion joint.

In Some Applications Bellows are used for vibration isolations. Bellows can also be used for Pipe Mis alignments and Volume compensations.(for liquid media).
