[0002] A coupling sleeve is a term in mechanical engineering, mainly used to connect pipes in a piping system. According to its use and type, coupling sleeves can be divided into four categories: ordinary coupling sleeves: used to connect ordinary pipes; elastic coupling sleeves: used to connect pipes with high pressure or large movement, which can reduce the vibration and noise of the piping system; telescopic coupling sleeves: used to connect pipes that need to expand and contract according to changes in ambient temperature, such as geothermal pipes; shock-absorbing compensation coupling sleeves: used to connect pipes that vibrate or bend and deform frequently. These coupling sleeves play an important role in the piping system, ensuring the effective connection between pipes and handling pipe movement or deformation caused by factors such as temperature changes and pressure fluctuations.
