For compensators with inner sleeves, care should be taken to ensure that the direction of the inner sleeve is consistent with the direction of medium flow. The hinge rotation plane of hinge-type compensators should be consistent with the displacement rotation plane.
For compensators that need to be cold-tightened, the auxiliary components used for pre-deformation should be removed only after the pipeline is installed.
Do not use the deformation method of the directly buried corrugated compensator to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the directly buried corrugated compensator, reduce the service life and increase the load of the piping system and equipment supporting components.
During the installation process, welding slag is not allowed to splash on the surface of the wave shell, and the wave shell is not allowed to suffer other mechanical damage.
After the piping system is installed, the yellow auxiliary positioning components and fasteners used for installation and transportation on the corrugated compensator should be removed as soon as possible, and the limit device should be adjusted to the specified position according to the design requirements to make the piping system in the environment There is sufficient compensation capability under the conditions.
All movable components of the directly buried corrugated compensator shall not be blocked by external components or limit their range of movement, and the normal movement of each movable part shall be ensured.
During the hydraulic test, the secondary fixed pipe frame at the end of the pipeline equipped with the compensator should be reinforced to prevent the pipeline from moving or rotating. For compensators used for gas media and their connecting pipelines, attention should be paid to whether temporary brackets need to be added when filling with water.
After the hydraulic pressure test, the accumulated water in the wave shell should be drained as soon as possible, and the inner surface of the wave shell should be dried quickly.
The insulation material in contact with the corrugated pipe of the directly buried corrugated compensator should not contain chloride ions.
