Thermal Expansion Joint Bellow Compensator
This flexible expansion joint is designed to absorb thermal movement, vibration, and mechanical stress in industrial pipeline systems. Featuring a multi-layer bellows structure, it provides excellent adaptability to axial, lateral, and angular displacement, protecting pipelines from damage caused by temperature changes and dynamic loads.
Key Performance Features
- Absorbs axial, transverse and angular thermal deformation
- Reduces equipment vibration impact on pipelines
- Compensates for pipeline deformation from seismic activity
- Protects against damage from land subsidence
