Double ball rubber joints (also known as double ball rubber flexible connectors or double ball rubber expansion joints) are commonly used flexible connection components in piping systems, playing an important role in shock absorption, noise reduction, and displacement compensation.
As an important component of piping systems, the performance of double ball rubber joints directly affects the safety and reliability of the entire system. Correct selection, standard installation, and regular maintenance are key to ensuring their long-term stable operation.

Through the high elasticity and airtightness of rubber, the following can be achieved in pipeline systems:
1. Absorb axial, lateral, and angular displacement of pipelines.
2. Reduce vibration and noise.
3. Compensate for thermal expansion and contraction caused by temperature changes.
4. Alleviate the impact force generated during system startup.

Common Issues and Solutions for Double Ball Rubber Joints in Pipelines
1. Leakage Issues:
Causes: Installation deviation, loose bolts, rubber ageing
Solutions: Re-centre the installation, tighten bolts evenly, replace the joint
2. Premature Ageing:
Causes: Medium corrosion, UV exposure, over-temperature use
Solutions: Select appropriate materials, add protective covers, control operating temperature
3. Abnormal Deformation:
Causes: Overpressure use, excessive displacement
Solutions: Check system pressure, install limit devices
4. Vibration Transmission:
Causes: Improper selection, insufficient pre-compression
Solutions: Re-select type, adjust pre-compression
