Expansion bellows



Expansion bellow

This type of expansion joints are indispensable elements in the construction of piping. They are used to compensate changes in length of the pipeline resulting from the effects of temperature. In some cases, they are able to intercept the vibration generated during the operation of pumps, motors, compressors or turbines. Compensated displacements may be axial, lateral and angular, respectively for needs. Properties of the compensator are based on the flexibility of bellows.

Such flexibility results from the form and number of the bellow waves; on the single-layer compensator it results on the thickness of the bellows; the multi-layer compensator flexibility results from the number of the waves, layers and material. Each expansion bellow is subjected to appropriate trials and has the adequate approvals.
