Specific functions of flange type bellows expansion joints during installation and operation

A Flange Type Bellow Expansion Joint is a compensation component commonly used in piping systems. It achieves the following key functions through the effective expansion and contraction deformation of its main working body, the bellows:

1.Absorption of Thermal Expansion and Contraction: The Flange Bellows Expansion Joint can compensate for changes in pipe dimensions caused by temperature variations, i.e., thermal expansion and contraction, thereby reducing stress concentrations and potential damage in the piping system.

 

2.Compensation for Displacement: In addition to thermal expansion and contraction, the Bellow Expansion Joint Flange Connected can also compensate for axial, lateral, and angular displacements of the pipeline. These displacements may be caused by factors such as pipe installation errors, mechanical vibration, or earthquakes.

 

3.Vibration and Noise Reduction: The flexible structure of the Metal Bellows Expansion Joints Flanged helps absorb and isolate vibrations, reducing their impact on the piping system and surrounding equipment. It also lowers noise levels during operation.

 

4.Equipment Protection: Installing a Flange Type Corrugated Expansion Joint at equipment inlets and outlets with strict force requirements can effectively reduce the forces exerted by pipes on the equipment, protecting it from damage.

 

5.Improvement of Flange Connection Sealing: By reducing stress at flange connections, the Flange Corrugated Expansion Joint helps enhance the sealing performance of the connection and reduces the risk of leaks.

 

6.Adaptation to Environmental Changes: In the event of ground settlement or other environmental changes, the Bellow Expansion Joint can adapt to these changes through its flexible characteristics, protecting the integrity of the piping system.

When installing and using Corrugated Compensator, proper installation and operation procedures should be followed to ensure that it can perform its intended compensation and protection functions and extend the service life of the piping system.
