The use of non-standard ripple compensator

National standard corrugated compensator installation

1, the national standard corrugated compensator should be checked before installation, model, specifications and pipeline configuration, must meet the design requirements.

2. For the compensator with inner sleeve, attention should be paid to aligning the direction of the inner sleeve with the direction of the medium flow, and the hinge plane of the hinge-type compensator should be consistent with the plane of displacement and rotation.

3, need to be "cold tight" compensator, pre-deformation of the auxiliary components should be installed after the pipeline can be removed.

4. It is strictly forbidden to use corrugated compensator deformation method to adjust the installation of pipelines to be out of tolerance so as not to affect the normal function of the compensator, reduce the service life, and increase the load of piping, equipment, and support components.

5. During the installation process, welding slag must not be allowed to splash on the surface of the wave shell, and the wave shell must not be subjected to other mechanical damage.

6. After installing the piping system, remove the yellow auxiliary positioning components and fasteners used for installation and transportation on the corrugated compensator as soon as possible, and adjust the position limiting device to the prescribed position according to the design requirements so that the piping system has the environmental conditions. Full compensation ability.

7. All moving elements of the compensator shall not be jammed or restricted by the external components. The normal movement of the active parts shall be ensured.

8. In the hydrostatic test, the secondary fixed pipe rack equipped with the end of the compensator pipe should be reinforced so that the pipeline does not move or rotate. For the compensator used in gas media and its connecting pipe, pay attention to whether it is necessary to add a temporary support when filling water. The 96 chloride ion content of the hydrostatic test water washing solution does not exceed 25 PPM.

9. After the hydrostatic test is completed, the water in the shell should be drained as soon as possible and the inner surface of the shell should be blown dry quickly.

10. The insulation material in contact with the compensator bellows shall not contain chlorine.
