1. Before installing the cf type single-flange force transmission expansion JOINT, check its model, specification and piping configuration to meet the design requirements.
2. For cf-type single-flange force transmission expansion joints, care should be taken to make the direction of the inner sleeve consistent with the flow direction of the medium, and the hinge rotation plane of the hinge type expansion joint should be consistent with the displacement rotation plane.
3. The cf type single-flange force transmission expansion joint that needs to be "cold-tightened", and the auxiliary components used for pre-deformation should be removed after the pipeline is installed.
4. It is strictly forbidden to use the deformation method of the cf type single flange force transmission expansion joint to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the cf type single flange force transmission expansion joint, reduce the service life and increase the piping system, equipment, and support The load of the component.

5. 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 be damaged by other machinery.

6. After the installation of the piping system is completed, the yellow auxiliary positioning components and fasteners used for installation and transportation on the cf-type single-flange force transmission expansion joint 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 pipe The department has sufficient Compensation capacity under environmental conditions.

7. All movable components of cf-type single-flange force transmission expansion joints shall not be jammed by external components or limit their movable range, and the normal movement of each movable part shall be ensured.

8. During the hydraulic test, the secondary fixed pipe frame with the end of the telescopic pipe should be reinforced to prevent the pipe from moving or rotating. For the cf-type single-flange force transmission expansion joint and its connecting pipeline for gaseous media, pay attention to whether it is necessary to add a temporary support when filling water.

The compressive strength of the raw materials of the CF type single-flange force transmission expansion joint device is improved, and the plastic deformation hardening temperature is increased, but the plastic deformation elongation is reduced. The reason is that in the process of plastic deformation of the cf-type single-flange force transmission expansion joint device, there is a process of texture entanglement and fibrosis, as well as the internal stress and production processing generated in the cf-type single-flange force transmission expansion joint device. The surface production processing and the depth of the hard bottom layer show the general specific heat treatment strength. Compensate and absorb the axial, lateral and angular thermal deformation of the pipeline; absorb equipment vibration and reduce the impact of equipment vibration on the pipeline; absorb the deformation of the pipeline due to earthquakes and ground subsidence.
