Installation Instructions of Expansion Joint

1. Before installing expansion joint, should check its type, specification and pipeline configuration, which must comply with the design requirements.
2. The expansion joint with inner sleeve should be paid attention to the inner sleeve in the same direction as the flow direction of medium, hinge rotation plane of hinged expansion joint should be consistent with the rotational plane.
3. Predeformation auxiliary components of the expansion joint that needs to be "cold" tight should be removed after installation.
4. It is forbidden to use expansion deformation method to adjust the pipeline installation error, so as not to affect the normal function of the expansion, reduce the service life of the components and increase the load of piping, equipment and supporting.
5. During installation, do not allow the slag splash to the shell surface and not allow the wave shell by other mechanical damage.
6. All active components of expansion joint shall not be stuck by external components or limited to the scope of its activity and should guarantee the active parts work normally.
