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 versatile and reliable component that serves as a vital link in various piping systems. Its primary function is to absorb movement, reduce vibration, and compensate for misalignment in pipelines, ensuring seamless operation and enhanced longevity of the entire system. This high-performance product is carefully engineered from premium-grade rubber, ensuring outstanding resistance to corrosion, chemical exposure, and extreme temperature conditions. 

        Featuring a double-sphere structure, this rubber bellows provides exceptional flexibility and resilience, enabling it to easily absorb axial, lateral, and angular movements. The dual-sphere design promotes even stress distribution, which helps prevent fatigue and extends the service life of the joint. In addition, it efficiently reduces vibration and noise, thereby improving the overall performance and reliability of the system.

        Our dedication to quality is evident in the strict testing procedures and comprehensive quality control applied to every Double Sphere Rubber Joint. We follow the most stringent industry standards to ensure each product not only meets but surpasses customer expectations. Backed by a team of seasoned experts, we are continuously advancing our technology and processes to deliver products that represent the cutting edge of innovation and reliability.

Characteristics:

1. Corrosion Resistance: Rubber expansion joints are made from high-quality rubber materials that exhibit excellent resistance to corrosion. They can be used with various media such as water, oil, and gases.  
 
 2. Elastic Deformation: Rubber expansion joints can absorb stresses and vibrations caused by temperature changes, vibrations, or pipe movements in pipeline systems through their elastic deformation. This helps protect the pipeline system from damage.  
 
 3. Shock Absorption and Noise Reduction: Rubber expansion joints effectively reduce the transmission of vibrations and noise in pipeline systems, providing a quieter and more stable working environment.  
 
 4. Easy Installation and Maintenance: Rubber expansion joints have a simple structure, making them easy to install and maintain. They also have low maintenance costs.

* 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.
