Dismantling Joints can play a decisive role in the design and layout of valves and pipelines. They are an essential aid for the removal and installation of pipe sections and valves. Without the use of a dismantling joint that offers longitudinal adjustment, it is not possible to insert a valve exactly into a pipe section. All thanks to this adjustability of the dismantling joint, the valve can be easily fitted next to the dismantling joint and the dismantling joint can be set exactly to the exact length which is needed prior to being securely connected to the flanges. The reverse sequence is used for dismantling where readjustment of the length of the dismantling joint makes way for enough space to loosen up and remove the valve. In both of the cases, the dismantling joint ensures fast installation and removal, these contribute to increased efficiency and reduces site operations and downtime. The procedure is much similar to pipe sections which had to be fitted together. Certain types of dismantling joints are also suitable for use without restraint in flexible pipelines. The dismantling joints can be used to fill gaps where a pump installed in a fixed position has to be connected to a pipe protruding from a wall.
