The safety of pipeline compensators is an issue that manufacturers cannot ignore; however, many customers are also unsure as to how to choose good compensators. The reliability of compensators depends on various factors such as design, manufacturing, installation, and operational management. Therefore, these aspects should also be taken into consideration when making a choice. The installation of compensators is an issue that cannot be ignored. Precautions for installing bellows compensators: 1. Before installation, the model, specifications, and piping configuration of the bellows compensator should be checked to ensure they meet the design requirements. 2. For bellows compensators with an inner sleeve, care should be taken to ensure that the direction of the inner sleeve is consistent with the flow direction of the medium; for hinge-type bellows compensators, the plane of rotation of the hinge should be aligned with the plane of displacement rotation. 3. For bellows compensators that require \"cold tightening,\" the auxiliary components used for pre-deformation should be removed only after the pipeline installation is completed. 4. It is strictly prohibited to use the deformation of wave compensators to adjust installation tolerances of pipelines, as this may affect the normal functioning of the wave compensators, reduce their service life, and increase the load on the piping system, equipment, and supporting components. 5. During installation, it is not allowed for welding slag to splash onto the surface of the wave shell, nor is it permitted for the wave shell to suffer any other mechanical damage. 6. After the piping system is installed, the yellow auxiliary positioning components and fasteners used for installation and transportation on the wave compensators should be removed as soon as possible. The limiting devices should then be adjusted to the specified positions in accordance with the design requirements, so that the piping system has sufficient compensation capacity under various environmental conditions. 7. All moving components of the wave compensator must not be blocked by external elements or have their range of motion restricted; normal operation of all moving parts must be ensured. 8. During the hydrostatic test, the secondary support brackets at the ends of the pipelines equipped with bellows compensators should be reinforced to prevent the pipelines from moving or rotating. For bellows compensators used in gas media and their connecting pipelines, attention should be paid to whether temporary supports are needed when filling them with water. The chloride ion content in the cleaning solution used for hydrostatic testing shall not exceed 25PPM.
