1. The model, specification and pipeline configuration of the pipeline expansion joint should be checked before installation, and must meet the design requirements.
2. It is strictly forbidden to use the method of deformation of the pipeline expansion joint to adjust the installation tolerance of the pipeline, so as not to affect the normal function of the pipeline expansion joint, reduce the service life and increase the load of the pipeline system, equipment and supporting members.
3. During the installation process, the 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.
4. After the installation of the piping system is completed, the yellow auxiliary positioning components and fasteners used for installation and transportation on the expansion joint of the pipeline should be removed as soon as possible, and the limiting device should be adjusted to the specified position according to the design requirements so that the piping system has good performance under environmental conditions. adequate compensation capacity.
5. All movable components of the pipeline expansion joint shall not be stuck by external components or restrict their range of activities, and the normal movement of each movable part shall be ensured.
6. During the hydrostatic test, the sub-fixed pipe frame with the pipe end of the pipe expansion joint should be reinforced so that the pipe does not move or rotate.
