2. For the expansion joint with inner sleeve, attention should be paid to make the direction of the inner sleeve consistent with the direction of media flow, and the hinge rotation plane of the hinge expansion joint should be consistent with the displacement rotation plane.
3. Cold tightening of the compensator is required, and the pre-deformed auxiliary members can be removed only after the pipeline is installed.
Pipeline expansion joint is a new product for pump, valve, pipeline and other equipment connection deployment and pipeline connection. They are connected into one whole by the whole bolt with certain displacement for testing according to the installation size on site during installation and maintenance. Axial thrust can go to the whole piping system. This not only improves efficiency, but also protects the connection of piping equipment such as pumps and valves.
