The metal rectangular corrugated compensator can mainly be used for multi-directional compensation in a small installation space. The product also has good high temperature resistance, noise reduction and shock absorption characteristics. The metal rectangular corrugated expansion joint must firstly pay attention to the following points when installing:
1.Before installing the metal rectangular corrugated compensator, check its model, specification and piping configuration, and it must meet the design requirements.
2.For compensators with inner sleeves, care should be taken to make the direction of the inner sleeve consistent with the flow direction of the medium. The hinge rotation plane of the hinge type expansion joint should be consistent with the displacement rotation plane.
3.The expansion joint 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 method of deformation of the corrugated expansion joint 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 of the piping system, equipment, and supporting components.
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 piping 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 has Sufficient compensation capability.
7. All movable components of the metal rectangular bellows shall not be jammed by external components or limit its range of movement, and the normal movement of each movable part shall be ensured.
