The working principle and function of the axial external pressure corrugated compensator.
Axial external pressure corrugated compensator is mainly used for axial compensation of direct buried pipeline, which has the ability of bending resistance, so the influence of sinking of pipeline can not be considered, and the product has the characteristics of large compensation volume and long life.
Axial external pressure corrugated compensator is used in the direct buried pipeline expansion element.
1、It is strictly forbidden to use the method of deformation of axial corrugated compensator to adjust the installation of the pipeline overrun, so as not to affect its normal function, reduce the service life and increase the load of the pipe system, equipment, support components.
2, the installation process, do not allow welding slag splash to the surface of the wave shell, do not allow the wave shell by other mechanical damage.
3, axial corrugated compensator in the installation should be checked before the model, specifications and pipeline configuration, shall meet the design requirements.
4, with the inner sleeve of the compensator should pay attention to make 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.
5, the need for cold tight compensator, pre-deformation of the auxiliary components used in the pipeline installation should be completed before removal.
6、After the installation of the pipe system, the corrugated compensator should be removed as soon as possible for the installation and transportation of 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、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.
Instructions for use: axial external pressure corrugated compensator is mainly applicable to axial compensation, while having a strong bending resistance, so do not consider the impact of pipe sinking, axial corrugated compensator shell and guide sleeve protection to achieve free expansion and contraction compensation, other performance and ordinary corrugated compensator the same.
8, axial corrugated 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.
