BSPT Threaded Rubber Expansion Joint NPT Double Sphere Flex Connector Compensator
Double Spheres Rubber Expansion Joint
Products:Rubber Expansion Joint
Rubber expansion joint, also known as compensator, is a flexible connector furnished by rubber bellow and swiveling steel flange. It allows pipeline for compression, extension and angular movement. It also reduces noise, and absorbs reaction force from vibration or pressure pulsation in fire pump operation.
Features:
1. Superb absorption vibration.
2. Effective for large eccentricity thermal and bending angle
3. Low-cost installation and operation.
4. BSPP,BSPT and NPT threaded unions available.
5. Vibration controller.
6. Absorb "Water hammer".
7. No electrolysis.
8. Less maintenance,no gasket needed.
9. Abrasive resistance 10 times greater than steel.
10. Will not fatigue.
