The working principle of corrugated compensator and installation and use requirements.
Corrugated compensator is a compensation device used to absorb the dimensional change of pipeline, duct or container due to thermal expansion and contraction by using the effective expansion and contraction of the elastic element of corrugated compensator, which is a compensation element. It can absorb axial, lateral, and angular displacement.
Compensator installation and use requirements
1 . Compensator should check its model, specification and pipeline configuration before installation, in line with the design requirements.
2 . Compensator with inner sleeve should pay attention to the direction of the inner sleeve and the direction of media flow, hinge type compensator hinge rotation plane should be consistent with the displacement rotation plane.
3 . Need to be "cold tight" compensator, pre-deformation of the auxiliary components used should be installed in the pipeline before removal.
4 . Corrugated compensator deformation method is strictly prohibited to adjust the installation of the pipeline overrun, so as not to affect the normal function of the compensator, reduce the service life and increase the load of the pipe system, equipment, supporting components.
5 . Installation process, do not allow the welding slag splash to the surface of the wave shell, do not allow other mechanical damage.
6 . After the installation of the pipe system, should be removed as soon as possible on the corrugated compensator used for installation and transportation of yellow auxiliary positioning components and fasteners, and according to the design requirements of the limit device to the specified position, so that the pipe system in the environmental conditions have full compensation capacity.
7 . Compensator all active components shall not be external components jammed or limit its range of activities, should ensure that the normal action of the active parts.
8 . Hydraulic test, should be equipped with compensator pipe end of the second fixed pipe frame for reinforcement, so that the pipeline does not move or rotate. For gas medium compensator and its connecting pipeline, pay attention to whether the need for additional temporary support when filling water. Hydraulic test water cleaning solution of 96 chloride ion content of not more than 25PPM.
9 . After the hydraulic test, the water in the wave shell should be drained as soon as possible, and quickly blow dry the inner surface of the wave shell.
10 . The insulation material in contact with the compensator bellows should be free of chlorine.
