High Quality Flexible Metal Bellows Expansion Joint

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.

Bellows expansion application

Because of its flexibility, bellows expansion can compensate the temperature difference deformation or other deformation between equipment and pipeline, prevent vibration, reduce the thrust of pipeline on equipment, and adapt to the uneven settlement of oil tank foundation. The bellows expansion can be widely used in chemical industry, oil refining, electric power, light industry, atomic energy, metallurgy, machinery, instrument, ship, aerospace and other departments. With the wide application of power pipeline and heat pipeline in industry and civil field, the requirement of bellows expansion is higher and higher.
