Dismantling joints play a decisive role in the design and layout of pipelines and valves. They are an essential aid during the installation and removal of pipe sections and valves. Without a dismantling joint offering longitudinal adjustment, it is almost impossible to insert a valve exactly into a pipe section. Thanks to this adjustability of the dismantling joint, the valve can be fitted next to the dismantling joint, and the dismantling joint can be set to the exact length required prior to being securely connected to flanges.
The reverse sequence is used for dismantling, where readjustment of the length of the dismantling joint creates enough space to loosen and remove the valve. In both cases, the dismantling joint guarantees fast installation and removal, thus contributing to increased efficiency and reducing site operations and downtime.
The procedure is similar where pipe sections have to be fitted together. Certain types of dismantling joints are also suitable for use without restraint in flexible pipelines. Finally, dismantling joints can be used to fill gaps e.g. where a pump installed in a fixed position has to be connected to a pipe protruding from a wall.
