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.
