Introduce of telescopic joint
The function of the gland type loose sleeve expansion joint is similar to that of the flexible clamp. It connects the pipes at both ends without welding the flange. Only by tightening the bolts and nuts, the sealing ring can prevent leakage and produce a certain amount of compensation for the pipes
Because there is a certain gap between the body and the expansion pipe, it has a certain axial displacement, which can effectively compensate and relieve the thrust of the pipe blind plate in the pipeline, and also facilitate the installation, maintenance and replacement of water pumps and valves.
It is actually the most ideal supporting product for pipeline installation and operation.
The gland limit expansion joint can prevent the leakage and damage of the compensation joint caused by the excessive displacement of the pipeline.
The gland limit expansion joint is mainly used for the loose connection of the pipeline that absorbs the axial displacement and bears the axial pressure thrust within the allowable displacement range.
