Product Description
Product Overview
Flexible rubber expansion joints are engineered connectors manufactured from natural and/or synthetic elastomers with fabric reinforcement and internal metallic components. These joints provide essential stress relief in piping systems by accommodating thermal movements and mechanical vibrations.
Key Advantages
- Superior compensation capabilities with high-performance rubber bellows for thermal expansion and compression
- Available with flange and threaded connection options
- Dual bellow design for absorbing substantial movement ranges
- Simultaneous compensation of axial, lateral, angular, and transverse movements
- Reduces pipeline tension and system stress
- Effectively dampens noise and vibration to protect connected equipment
- Compensates for ground settlement, particularly in new construction
- Elastic structure ensures reliable sealing where pipelines penetrate walls
