TORAFLEX® S50 Metal Expansion Joints (S50 Metal Compensators) are flexible unions designed for rigid pipework systems to absorb axial thermal movements caused by temperature changes. They consist of a corrugated Omega-shaped metallic bellow with flanged ends and an internal sleeve that protects the bellow from wear and flow turbulence. The S50 type incorporates limit rods as standard to control movement and enhance operational safety.

Correct pipe system arrangement and installation in accordance with the TORAFLEX® Installation, Operating and Maintenance Manual is essential to ensure safe, reliable, and efficient performance.
