Factory Supply Vulcanized 8inch PN16 Double Sphere Corrugated Ss304 Flange Connector Coupling Flexible Rubber Joint

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.

Connecting Data

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.

Application Areas

1. Building Plumbing Systems:

• Pump inlet and outlet vibration damping
• Displacement compensation for high-rise building piping systems

2. Industrial Piping Systems:

• Chemical piping medium isolation
• Thermal expansion and contraction compensation for heating piping systems
• Piping connections for air compressors and refrigeration equipment

3. Municipal Engineering:

• Water supply networks
• Wastewater treatment systems
• Fire protection pipeline systems

4. Special Applications:

• Ship pipeline systems
• Power plant circulating water systems
• Oil transportation pipelines

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
