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.
