German standard flexible rubber joint
Single Rubber Joint
Rubber Joint
- Flanged single sphere expansion rubber joint can greatly reduce pipeline system vibration and noise, can solve the problem of joint displacement, axial expansion, etc.
- According to different materials manufacture, flexible rubber joint can be made into many kinds: acid resistance, alkali resistance, corrosive resistance, oil resistance, heat resistance, adapt to many mediums and different environment.
- Material is polar rubber, good sealing, light weight, easy installation, long service life, avoid contacting with sharp metal device.
- If use overhead, can match with elastic support, when installation, bolt with diagonal method to tighten up.
- If pipeline pressure is high, use bolt connect the flange both ends.
- Flange connection standard is .
Features
- High-capacity acoustic damping
