The dismantling joint consists of the main body,the sealing ring,the gland,the telescopic short pipe and other main parts.It is a new product that connects pumps,valves and other equipment with pipelines.It connects them into a whole through full bolts,and has a certain displacement. In this way, it can be adjusted according to the installation size on site during installation and maintenance, and the axial thrust can be transferred back to the whole pipeline during work.This not only improves work efficiency,but also plays a certain protective role for pumps,valves and other equipment.
