Comprehensive Guide to Metal Expansion Joint Installation:
1. Prior to installation, the metal compensator shall be inspected for its model, specifications, and piping configuration to ensure compliance with the design requirements.
2. For compensators with an inner sleeve, ensure that the sleeve is oriented in the same direction as the flow of the process medium; for hinged compensators, the plane of hinge rotation must coincide with the plane of displacement.
3. For compensators requiring “cold tightening,” the auxiliary components used for pre‑deformation shall be removed only after the piping system has been fully installed.

4. It is strictly prohibited to use deformation of bellows expansion joints to compensate for installation deviations, as this may impair the joint’s normal functionality, shorten its service life, and increase the loads on the piping system, equipment, and supporting structures.
5. During the installation of metal expansion joints, welding spatter must not be allowed to splash onto the bellows surface, and the bellows must be protected from any other mechanical damage.
6. Upon completion of piping installation, promptly remove the yellow auxiliary locating components and fasteners used during installation and transportation on the bellows expansion joint, and adjust the limit devices to their specified positions as required by the design, ensuring that the piping system maintains adequate compensation capacity under ambient conditions.
