Corrugated compensator

Ripple compensator is also called expansion joint or expansion joint. Composed of corrugated pipes (elastic elements) and accessories such as end pipes, brackets, flanges, and conduits. It belongs to a type of compensation component. By utilizing the excellent expansion and contraction effects of its working body, the corrugated pipe can absorb dimensional changes caused by thermal expansion and contraction in pipelines, conduits, containers, etc., or compensate for axial, lateral, and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction. Widely used in modern industry. In terms of heating, in order to prevent deformation or damage of the heating pipeline caused by thermal elongation or temperature stress during heating, compensators need to be installed on the pipeline to compensate for the thermal elongation of the pipeline, thereby reducing the stress on the pipe wall and the force acting on the valve or support structure

Classification of compensators: ⑴ Axial type, ⑵ Transverse type, ⑶ Angular type

Function of Compensator

① Compensate for axial, transverse, and angular thermal deformation of absorption pipelines.

② The expansion and contraction of the corrugated compensator facilitates the installation and disassembly of valve pipelines

③ Absorb equipment vibration and reduce the impact of equipment vibration on pipelines

④ Absorb the deformation of pipelines caused by earthquakes and subsidence
