1. The compensator shall check its model, specifications and piping configuration before installation, and must comply with the design requirements.
2. The compensator for the inner sleeve should note that the direction of the inner sleeve is consistent with the flow direction of the medium, and the hinge of the hinge type compensator should be consistent with the displacement rotation plane.
3. It is necessary to carry out the "cold tight" compensator. The auxiliary components used in predeformation should be removed after the pipeline is installed.
4, it is forbidden to use corrugated compensator deformation method to adjust the pipeline installation error, so as not to affect the normal function of the compensator, reduce the service life of the components and piping, equipment, supporting the load.
5. During installation, the welding slag is not allowed to splash into the surface of the wave shell, and the wave shell is not allowed to be damaged by other machines.
6, piping installation has been completed, should be removed as soon as possible on the corrugated compensator is used as the installation of transport yellow auxiliary positioning components and fasteners, and switch to a specified position limit device according to design requirements, make the piping have ample compensation ability under the environmental conditions.
7. All active components of the compensator shall not be deadlocked or restricted by external components, and the normal movements of the active parts shall be ensured.
8. When hydraulic test, it shall be strengthened by the secondary fixed pipe rack equipped with compensator tube, so that the pipeline does not move or rotate.For the compensator and its connecting line for the gas medium, it is necessary to pay attention to whether the temporary support should be added when filling the water.The content of 96 chloride ions in water pressure test is no more than 25PPM.
After the water pressure test is finished, the water in the shell should be removed as soon as possible, and the surface of the wave shell will be dried quickly.
10. The insulation material contacting with the compensator bellows shall not contain chloride ion.
