- Compensates for axial, lateral, and angular movements
- Reduces noise and vibration in piping systems
- Resistant to corrosion and aging
- Easy installation with standard ANSI flange compatibility
Control Rods: For applications where excessive movement or pressure thrust could damage the expansion joint or adjacent equipment, control rods (tie rods) are often recommended or required. These rods limit the maximum extension of the joint.
Pressure and Temperature Ratings: Ensure the expansion joint's pressure and temperature ratings are suitable for the specific application. Different rubber materials have different operating limits.
Movement Capabilities: Understand the maximum allowable axial, lateral, and angular movements the joint can accommodate, and ensure these align with the system's needs. Note that typical single-sphere joints are designed for non-concurrent movements.
Installation: Proper installation is crucial for the longevity and performance of the expansion joint. Floating flanges facilitate easier alignment during installation.
