TORAFLEX® S25 Metal Expansion Joints (Type 25 Metal Compensators) are flexible unions designed for rigid piping systems to absorb axial thermal movements caused by temperature variations. These expansion joints consist of a corrugated Omega-shaped metallic bellow with welded ends and an internal sleeve that protects the bellow from wear, flow turbulence, and erosion.

Proper pipe system layout and installation in accordance with the TORAFLEX® Installation, Operating and Maintenance Manual are essential to ensure long-term safety, reliability, and efficient performance.
