Axial Movement
Movement that changes the distance between the ends along the longitudinal axis of the joint.
Metallic Expansion Joints for Controlled Piping Movement
Metallic bellows assemblies designed to accommodate axial, lateral and angular movement in industrial piping systems.
Include with your requirement
Final configuration depends on the complete movement requirement and operating conditions, not on nominal size alone.
- Operating temperature
- Pressure
- Process medium
- Axial, lateral and angular movement
- Connection arrangement
- Project specifications
Review the operating duty before choosing a configuration
Metallic expansion joints use flexible metal bellows within an engineered assembly. The arrangement is selected around the specified movement, service conditions, end connections and surrounding piping system.
The operating duty includes the service conditions, required movement and connection arrangement. Send the available information first; missing details can then be identified before a product route is proposed.
Lateral Movement
Transverse movement that offsets one end of the joint relative to the other.
Angular Movement
Rotational movement that changes the angle between the two ends of the joint.
When metallic expansion joints may be considered
- 01Configurations for specified axial, lateral and angular movement
- 02Compact bellows assemblies for industrial piping connections
- 03Flanged, welded or project-specific connection arrangements may be reviewed
- 04Hardware and accessories are coordinated with the selected configuration
Configurations available for requirement review
The final arrangement can only be identified after the service conditions, dimensions, movement and project requirements are reviewed.
01
Single Expansion Joints
A single-bellows arrangement considered primarily for axial movement within a suitably designed piping system.
