Introduction: Corrugated compensator, also known as compensator, or expansion. It is composed of bellows (an elastic element) and accessories such as end pipe, bracket, flange and conduit. It is mainly used in a variety of pipes, which can compensate the thermal displacement and mechanical deformation of pipes

ripple Compensator It's also known as a compensator, or Telescopic device It is composed of bellows (an elastic element) and accessories such as end pipe, bracket, flange and conduit. It is mainly used in all kinds of pipelines. It can compensate the thermal displacement, mechanical deformation and absorb all kinds of mechanical vibration. It can reduce the deformation stress of pipeline and improve the service life of pipeline. Corrugated compensator The connection mode is divided into flange connection and welding. The directly buried pipeline compensator is generally welded (except for trench installation)
It is a kind of expansion compensation device to compensate for the thermal expansion caused by the change of the size of the expansion tube or the expansion pipe. It can absorb axial, transverse and angular displacement.
The axial type bellows compensator is composed of a bellows and two end joints. It absorbs the radial offset of the pipeline through the flexible deformation of the bellows. The two sides of the connecting pipe are connected with the pipe. The fixed bolt is the rigid support of the bellows during the transportation of the compensator. Axial type internal pressure type corrugated compensator is mainly used to compensate radial displacement and lateral displacement or axial and transverse displacement. It has the ability to compensate angular displacement, but it is not used to compensate angular displacement.
Installation and use need to pay attention to the following points: 1, compensator before installation to check its model, specification and pipeline configuration, must meet the design requirements. 2. For the compensator with inner sleeve, attention should be paid to make the orientation of inner sleeve cylinder consistent with the direction of medium flow, and the hinge rotation plane of hinge type compensator should be consistent with the displacement rotation plane. 3. For the compensator that needs to be "cold tight", the auxiliary components for pre deformation should be removed after the pipeline installation. 4. It is strictly forbidden to adjust the installation deviation of the pipeline by means of deformation of the corrugated compensator, so as to prevent the normal function of the compensator, reduce the service life and increase the load of piping, equipment and supporting components. 5. During installation, welding slag is not allowed to splash on the surface of wave shell, and other mechanical damage is not allowed. 6. After the installation of piping system, the Yellow auxiliary positioning components and fasteners for installation and transportation on the bellows compensator shall be removed as soon as possible, and the limiting equipment shall be adjusted to the required position according to the design requirements, so that the pipeline system has sufficient compensation capacity under the environmental conditions. 7. All moving elements of the compensator shall not be jammed or restricted by external components, and the normal posture of each moving position shall be ensured. 8. During the hydraulic test, the secondary fixed pipe support with compensator is solved to strengthen the structure, so that the pipeline will not move or rotate. For the compensator used for gas medium and its connecting pipe, it is necessary to add temporary support when filling water. The 96 chloride ion content of the cleaning solution for water pressure test shall not exceed 25ppm. 9. After the hydrostatic test, the accumulated water in the wave shell should be drained as soon as possible, and the inner surface layer of the wave shell should be dried quickly. 10. The insulation material in contact with compensator bellows shall be chlorine free.
