Vibration Reduction
Flexible construction can help reduce vibration transmitted through connected piping.
Rubber Expansion Joints for Flexible Piping Connections
Flexible connectors used to reduce vibration and noise while accommodating movement within piping systems.
Include with your requirement
The selected arrangement must be matched to the complete service conditions and piping requirements.
- Nominal size and length
- Process medium
- Temperature
- Pressure
- Movement requirements
- Flange and connection arrangement
Review the operating duty before choosing a configuration
Rubber expansion joints are elastomeric flexible connectors used where movement accommodation, vibration isolation or noise reduction is required. Compound, reinforcement, arch profile, flange arrangement and restraint requirements must be matched to the complete duty.
The operating duty includes the service conditions, required movement and connection arrangement. Send the available information first; missing details can then be identified before a product route is proposed.
Noise Reduction
Rubber connectors may be considered where structure-borne noise reduction is part of the requirement.
Movement Accommodation
The required movement must be reviewed with the medium, temperature, pressure and connection arrangement.
When rubber expansion joints may be considered
- 01Flexible connection for specified piping movement
- 02Helps reduce the transmission of vibration and structure-borne noise
- 03Compact arrangements for selected piping and equipment connections
- 04Different compound and flange arrangements can be reviewed for the stated service
Five elements reviewed as one flexible connection
Rubber expansion-joint selection involves more than choosing an elastomer name. The tube, reinforcement, cover, arch geometry and end arrangement must work together for the specified piping duty.
- 01
Process-facing tube
The inner elastomer surface is selected against the exact medium, concentration and operating temperature.
- 02
Reinforcing carcass
Internal reinforcing layers support pressure retention and help the connector maintain its intended form.
- 03
External cover
The outer elastomer layer protects the reinforcing structure from the installation environment.
- 04
Arch profile
The arch arrangement is reviewed against required movement, available length and operating conditions.
- 05
Flange and restraint arrangement
Mating dimensions, flange details and any required control hardware are considered with the surrounding piping system.
Configurations available for requirement review
The final arrangement can only be identified after the service conditions, dimensions, movement and project requirements are reviewed.
