Custom Dn150 Jis Galvanized Carbon Steel Epdm Connector Double Ball Bellows Flanged Rubber Joint
Technical advantages of double-sphere flexible rubber joint
1. Small size, light weight, good elasticity, easy installation and maintenance.
2. After installation, it can absorb the lateral, axial and angular displacement caused by pipeline vibration; it is not restricted by pipeline eccentricity and flange non-parallelism.
3. After installation, it can reduce the noise caused by pipeline water pump and other vibrations, and has strong vibration absorption ability.
4. Seamless high-pressure rubber joints can more effectively prevent corrosive media from eroding the inner wall of rubber joints in high-temperature, acid-resistant, alkali-resistant and oil-resistant pipelines, thereby increasing service life.

Installation notes
1. When installing the double ball rubber joint, it is strictly forbidden to install it beyond the displacement limit.
2. The installation bolts should be symmetrical and tightened gradually to prevent local leakage.
3. For working pressures above 1.6MPa, the installation bolts should have elastic pressure pads to prevent the bolts from loosening during operation.
4. When installing vertically, both ends of the joint pipe should have vertical force support, and anti-pull-off devices can be used to prevent pull-off under pressure during operation.
