Material and Connection of Telescopic Dismantling Joint

Telescopic dismantling joint is one of the most commonly connector used in pipeline protection. Gongyi Xinli Pipeline Equipment Company is specialized in telescopic dismantling joint manufacturing with more than 19-year experience. The material and connection of telescopic dismantling joint are as follows:

Telescopic dismantling joint can be divided into two kinds, one is metallic telescopic dismantling joint, the other is rubber dismantling joint. According to different material metallic telescopic dismantling joint is divided into: cast iron dismantling joint, galvanized telescopic dismantling joint, steel telescopic dismantling joint. The connection can be two sides flange or one side flange the other welding. Telescopic dismantling joint can be axial expansion in a certain range, which can greatly facilitate the installation and removal of the valves. The telescopic dismantling joint can move freely within the allowance of the mating pipe, once  beyond the maximum allowance it is limited to ensure the safe operation of pipelines.

The functions of telescopic dismantling joint are as follows: compensate absorb axial, lateral, angular thermal deformation of pipeline; absorb and reduce vibration of pipeline equipment; absorption deformation caused by earthquakes and subsidence.
