The flange limited expansion joint is a connection device used in pipeline systems. It is mainly used to absorb the axial, lateral and angular displacement of the pipeline, and withstand various mechanical vibrations. It is suitable for accessories such as pumps and valves.

The limited expansion joint is a new product for connecting equipment such as pumps and valves with pipelines. They are connected by full bolts to form a whole and have a certain displacement. In this way, they can be adjusted according to the on-site installation dimensions during installation and maintenance. During operation, the axial thrust can be transmitted back to the entire pipeline. This not only improves work efficiency, but also plays a certain protective role for equipment such as pumps and valves.
