The hinged metal compensator is also customarily called expansion joint, expansion joint, and consists of bellows (a kind of elastic element) which forms its working body and accessories such as end pipes, brackets, flanges and conduits. Hinged metal compensator installation instructions Hinged metal compensator should be checked before installation for its type, specification and pipeline configuration, which needs to meet the design requirements. Compensator with inner sleeve should pay attention to the direction of the inner sleeve and the direction of media flow, hinge type compensator hinge rotation plane should be consistent with the displacement rotation plane. Need to be "cold tight" compensator, pre-deformation of the auxiliary components used in the pipeline installation should be completed before removal. It is strictly forbidden to use the method of deformation of the corrugated compensator to adjust the installation of the pipeline overrun, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the pipe system, equipment and supporting components. During the installation process, do not allow the welding slag splash to the surface of the wave shell, do not allow the wave shell by other mechanical damage. After the installation of the pipe system, should be removed as soon as possible on the corrugated compensator used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements of the limit device to the specified position, so that the pipe system in the environmental conditions have full compensation capacity. All active components of the compensator shall not be jammed by external components or limit its range of activities, and shall ensure the normal action of each active part.
Product role Compensate and absorb pipeline axial, lateral and angular thermal deformation. Absorb equipment vibration, reduce the impact of equipment vibration on the pipeline. Absorb the deformation of the pipeline by earthquake and land subsidence. Application range Pipeline with large deformation and displacement and restricted space position. Large diameter pipeline with large deformation and displacement but low working pressure. Equipment that needs to limit the receiver load. Pipelines requiring absorption or isolation of high frequency mechanical vibration. Pipes that require absorption of earthquake or foundation settlement.
