Metal Bellows (they are also
called compensators) are compensating elements for thermal
expansion and relative movement in pipelines, containers and
machines. They consist of one or more metal bellows, connectors at
both ends, and tie rods that depend on the application. They are
differentiated according to the three basic types of movement:
axial, angular and lateral expansion
joints. Metal Bellows are elastic vessels that
can be compressed when pressure is applied to the outside of the
vessel, or extended under vacuum. When the pressure or vacuum is
released, the bellows will return to its original shape (provided
the material has not been stressed past its yield
strength). 1.Reasonable structure, good elasticity, large
range of compensation pipeline and little counterforce to the
brackets of pipeline. 2.Shock absorption and noise decrease, heat
and dust insulation, environmental protection and simple structure
bracket. 3.The displacement can be deflected to prevent
damagment caused by subsidence of connected brackets and equipment
base. It can adapt itself to the centrifugal difference of pipeline
installation to provide convenience to installation and
maintenance. 4.Good resistance to milling, heat, aging and
corrosiveness and long service life. 5.Little resistance and little weight. Each
performance is better than the compensation device of other
materials. 6.The temperature range of media is
wide:*****0°c
