Product Overview
Matrix Industrial Traders Twin Sphere Rubber Expansion Joints provide enhanced axial compression, elongation, and angular deflection compared to standard single arch bellows. Specifically designed to isolate mechanical vibrations generated by centrifugal pumps, chillers, and compressors, safeguarding connected pipework from stress fatigue.
Key Features
- Twin Arch Configuration: Higher flexibility and deflection capability with low spring rates.
- Reinforced Elastomer Carcass: High-tensile nylon cord and synthetic rubber compound resist burst pressures and aging.
- Acoustic and Vibration Damping: Significantly reduces sound transmission along pipeline networks.
- Floating Electro-Galvanized Flanges: Drilled to ANSI Class 150 or DIN PN16 for easy bolt alignment without twisting the elastomer body.
