Telescopic tube, principle and installation requirements

Telescopic tube, also known as expansion joints, expansion joints, compensators, divided into: bellows, sleeve compensator, rotating compensator natural compensator, square and other major types, with bellows of the more common, mainly to protect the pipeline operation, has the following functions:
1. the compensation to absorb axial, lateral, angular deformation.
2. absorption of vibration to reduce the effects of vibration on the pipeline.
3. involving earthquakes, sinkholes on the deformation of the pipe.
