Fixed-range expansion joints are special expansion elements that fall into the axial expansion joint category and are used to absorb thermal expansions in pipelines in the axial direction. These expansion joints extend the overall life and working life of the installation by controlling longitudinal movements caused by temperature changes in the piping system.

The piping system is formed from each section by separating different expansion zones, and is isolated from each other by fixed points placed in place. Thanks to this electrical approach, the expansion movement occurring in a certain area is absorbed only by the fixed-range axial expansion joint belonging to that area.

In this way, other places in the system are not exposed to unnecessary load, and expansion and loosening of connections along the line are prevented. Fixed-variable expansion joints are preferred to provide reliable performance, especially in applications with high temperature differences.
