Steel telescopic, rubber telescopic, stainless steel telescopic. The telescopic device can expand and contract axially within a certain range, and can also overcome the offset caused by different axial directions of pipe docking within a certain angle. It can greatly facilitate the installation and disassembly of valve pipes, and can be freely adjusted within the allowable expansion and contraction of the pipes. Once the maximum expansion and contraction is exceeded, it will act as a limiter to ensure the safe operation of the pipeline. Mainly to ensure the safe operation of the pipeline, it has the following functions: compensates and absorbs the axial, transverse and angular thermal deformation of the pipeline, absorbs equipment vibration, reduces the impact of equipment vibration on the pipeline, and absorbs the deformation of the pipeline caused by earthquakes and ground subsidence.
