The shock-absorbing bellows compensator (also known as the shock-absorbing bellows compensator or anti-seismic bellows expansion joint) is a flexible connection device used in pipeline systems. It is mainly used to absorb vibration, compensate for displacement (such as thermal expansion and contraction), and reduce noise transmission, while also having an anti-seismic function. The following are its key features and application analysis:

Core function
Shock absorption and vibration isolation

The flexible deformation of the corrugated pipe absorbs the impact generated by the operation of equipment (such as pumps and fans) or external vibration on the pipeline, reducing the influence of vibration transmission on the pipeline and supporting structure.

Displacement compensation

Compensate for the axial, lateral or angular displacements of the pipeline caused by temperature changes (thermal expansion and contraction), installation errors or foundation settlement.

Seismic performance

Under earthquakes or sudden impact loads, the stress of the pipeline system is buffered through elastic deformation to prevent pipeline rupture or connection failure.

Noise reduction and sealing

Reduce noise generated by fluid flow or vibration and maintain the sealing of the pipeline system (especially suitable for high-pressure or vacuum environments).
