Multi Gimbal type Expansion Joint as customer's requirements
Product description
Compensator is also customarily called expansion joint, expansion
joint, corrugated compensator is a compensation element.The
effective telescopic deformation of the bellows as the working body
can be used to absorb the size changes of pipelines, conduits and
vessels caused by thermal expansion and cold contraction, or to
compensate the axial, transverse and angular displacements of
pipelines, conduits and vessels for noise reduction and vibration
reduction.
Installation requirements
The type, specification and piping configuration of the compensator
should be checked before installation and must meet the design
requirements."Cold tight" compensator is needed, and the auxiliary
components used for pre-deformation shall be removed after pipeline
installation.During installation, welding slag is not allowed to
splash on the surface of the wave shell, and other mechanical
damage is not allowed to the wave shell.All moving components of
the compensator shall not be jammed by external components or limit
their range of motion. The normal motion of each moving part shall
be guaranteed.After the hydrostatic test, the water in the wave
shell should be drained as soon as possible, and the inner surface
of the wave shell should be quickly blown dry.For the compensator
with inner sleeve, attention should be paid to make the direction
of inner sleeve bobs consistent with the direction of medium flow,
and the rotational plane of hinge compensator should be consistent
with the rotational plane of displacement.
Advantages
• Protects the pipeline systems against collapse and breakages by
compensating seismic motions (earthquake) and large lateral and
angular movements.
• Movement of bellows is more controlled.
• Internal flow liners for eliminating velocity problems may be
fitted.
• Anchors only require to absorb spring forces.
• Pressure thrust is restrained by the hardware
Requirements for use
It is strictly forbidden to use the method of deformation of ripple
compensator to adjust the installation error of pipeline, so as not
to affect the normal function of compensator, reduce the service
life and increase the load of piping, equipment and supporting
members.After installation of piping system, the yellow auxiliary
positioning member and fastener used for installation and
transportation on corrugated compensator should be removed as soon
as possible, and the limit device should be adjusted to the
specified position according to design requirements, so that the
piping system has sufficient compensation ability under
environmental conditions.During the hydrostatic test, the secondary
fixed pipe rack with compensator pipe end should be reinforced so
that the pipe does not move or rotate.For the compensator for gas
medium and its connecting pipeline, it is necessary to pay
attention to whether additional temporary support is needed when
filling water.The content of 96 chlorine ions in the cleaning
solution for hydrostatic test shall not exceed 25PPM.The insulation
material in contact with the bellows of the compensator shall be
free from chlorine.
Applicable temperature: -196℃~+1080℃
Widely used: chemical industry, petroleum, aerospace, food,
metallurgy, steel, medicine, ship, thermoelectric, water supply,
heat supply, natural gas, etc.
