NHFLEX-B TYPE Flanged Double Sphere Flexible Rubber Expansion Joints Pipe Connector Rubber Compensator
Double Sphere Rubber Compensator Pipeline Expansion Joint for Vibration AbsorberDouble Sphere Rubber Compensator Pipeline Expansion Joint for Vibration AbsorberDouble Sphere Rubber Compensator Pipeline Expansion Joint for Vibration Absorber       

The double sphere rubber joint is a reliable and versatile component widely applied in piping systems. Its primary function is to absorb movement, minimize vibration, and compensate for misalignment, ensuring smooth operation and extending the service life of the pipeline. Constructed from premium rubber materials, it offers excellent durability and strong resistance to corrosion, chemicals, and extreme temperature conditions, making it a dependable choice for demanding environments.

With its double-sphere configuration, this rubber bellow delivers superior flexibility and resilience, allowing it to accommodate axial, lateral, and angular movements with ease. The dual-sphere design ensures balanced stress distribution, reducing the risk of fatigue and enhancing the joint’s longevity. Additionally, it effectively dampens vibration and noise, improving overall system efficiency and reliability.


Characteristics:

1. Outstanding Corrosion Resistance: Made from premium rubber compounds, these expansion joints resist corrosion and can be used safely with various media such as water, oil, and gases.

2.  High Flexibility for System Safety: Their elastic properties allow them to absorb stresses from thermal changes, vibrations, and pipe displacement, helping protect the pipeline system from damage.

3.  Vibration Damping and Noise Control: By minimizing the transfer of vibration and sound, rubber expansion joints create a quieter, more stable operating environment.

4.  Simple Installation and Low Upkeep: With a straightforward design, these joints are quick to install, easy to service, and require minimal maintenance.

* Control units must be used when piping is not properly anchored.
   The rated pressure can be above 2.5MPa, but products will only be sold with control units.
   Pressure rating is based on 30ºC operating temperature. The pressure rating is reduced at higher temperatures.
   Rated pressure in the above table is the maximum "working pressure". Test pressure is 1.5 times "working pressure", Burst pressure
is 4 times "work pressure".

Double Sphere Rubber Compensator Pipeline Expansion Joint for Vibration Absorber

Compensating for Thermal Expansion and Contraction: Rubber expansion joints compensate for thermal expansion and contraction caused by temperature variations in the pipeline. They prevent excessive stress on the pipeline system due to temperature changes, thereby protecting the pipes from damage.

  Absorbing Vibrations and Impacts: Rubber expansion joints absorb stresses caused by vibrations and impacts in the pipeline system, reducing the transmission of vibrations and noise. This helps protect the pipeline and related equipment from damage.

  Compensating for Pipe Movements: During installation and operation, pipeline systems may experience certain degrees of pipe movement. Rubber expansion joints compensate for these movements, ensuring the proper functioning of the pipeline system.

  Leak Prevention: Rubber expansion joints provide sealing performance in pipeline systems, reducing the risk of leaks and ensuring the safe operation of the pipelines.
