How to install metal bellows
Before installing metal bellows, you should check its model, specifications and pipe configuration. It must meet the design requirements. Before installing metal bellows, you should check its model, specification and pipe configuration. situation and must meet design requirements.
For compensators with an inner sleeve, 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 a hinge-type compensator 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.
It is strictly forbidden to use the method of deforming the corrugated compensator to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the compensator, reduce the service life and increase the load on the supporting components of the piping system equipment.
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, so that the piping system can operate under environmental conditions. There is sufficient compensation capability.
All movable components of the compensator must not be blocked by external components or limit their range of movement, and the normal movement of each movable part should be ensured.
During the hydraulic test, the secondary fixed pipe frame at the end of the pipe equipped with the compensator should be reinforced to prevent the pipe 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. The chloride ion content of the cleaning fluid used in the hydrostatic test shall not exceed.
After the hydrostatic 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 compensator bellows should be free of chloride ions.
