High Quality Flexible Metal Bellows Expansion Joint

 

Bellows expansion is a kind of flexible thin-wall transverse bellows expansion joint, which is composed of stainless steel bellows body, flange, limit rod and limit ear plate. Bellows expansion, also known as metal bellows expansion joint, is a kind of prefabricated component for pipeline compensation, which is widely used in electric power engineering, petrochemical industry, heating, steel, urban construction and other industries. Its function is to compensate the power or connection between heat pipe network and mechanical equipment. The bellows expansion joint compensates the displacement of long pipeline system software or mechanical equipment caused by temperature difference (or molecular thermal movement) through axial expansion form or angle change, and eliminates the vibration of mechanical equipment under driving, parking or all normal operation standards, which can effectively reduce the pipeline deformation and improve the service life of the pipeline system. Metal bellows expansion joint can be processed into different models according to different needs.

 

Performance of bellows expansion

 

The main elastic element of bellows expansion is stainless steel bellows. Through the expansion and bending of bellows, the bellows expansion compensates the pipeline in axial, transverse and angular directions. Bellows expansion can play the following roles:

1. The bellows expansion absorbs the axial, transverse and angular thermal deformation of the pipeline.

2. Bellows expansion can absorb equipment vibration and reduce the influence of equipment vibration on pipeline.

3. Bellows expansion can absorb the pipeline deformation caused by earthquake and land subsidence.
