Custom DN125 Pn16 Ss304 EPDM Connector Double Ball Bellows Flanged Rubber Joint
The meanning of double ball rubber joints
Rubber joints, also known as flexible rubber joints, rubber soft joints, soft joints, rubber expansion joints, shock absorbers, etc., are pipeline connectors with high elasticity, high airtightness, medium resistance, and weather resistance.
Performance characteristics of double ball rubber joints
Rubber joints utilize the advantages of high elasticity, high gas resistance, medium resistance, weather resistance, and radiation resistance of rubber, which can reduce pipeline vibration and noise, and compensate for thermal expansion and contraction caused by temperature changes.
Product advantages
1. The sphere is longer and has better vibration and noise reduction effects
2. Good telescopic displacement performance and longer service life than single ball rubber joints
3. Small size, light weight, good flexibility, and convenient installation and maintenance
4. Absorbable displacement after installation
5. Reduce noise

Production Process
Installation Case
Installation of rubber joint
1.Installation bolts should be symmetrical and gradually pressurized to prevent local leakage.
2.1.6MPa above working pressure, installation bolts should have elastic pad to prevent bolts loosening when working. 3.Vertical force support should be provided at both ends of the joint pipe during vertical installation, and anti-pull-off device can be adopted to prevent working pressure pull-off.
4.Rubber joints should be installed away from the heat source. Ozone. Strictly prohibit strong radiation light exposure and the use of non-conforming media.
5.Rubber joints shall be strictly prohibited from cutting the surface and sealing surfaces during transportation and handling.
