Pressure Balanced Expansion Joints
Designed to eliminate pressure thrust while allowing axial and lateral movement, pressure balanced expansion joints ensure safety and stability in critical piping systems.
Maintain System Stability While Absorbing Axial Movement
Pressure balanced expansion joints are specially engineered to absorb thermal movement without transferring pressure thrust to adjacent equipment or anchors. Ideal for sensitive piping systems, these joints ensure system stability, protect connected components, and maintain alignment — all while compensating for axial and lateral movements.
Key Features
Neutralizes pressure thrust while allowing movement
Handles axial and lateral deflections
Ideal for sensitive equipment and weak anchoring systems
Custom-built for inline or elbow configurations
Available in metallic bellows with high-pressure ratings
