Product Description

Product Description

NHFLEX-B TYPE Flanged Double Sphere Flexible Rubber Expansion Joints Pipe Connector Rubber Compensator
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 exceptional product is meticulously constructed using high-quality rubber materials, guaranteeing exceptional resistance to corrosion, chemicals, and extreme temperatures.

With its double sphere design, this rubber bellows offers unparalleled flexibility and elasticity, allowing it to accommodate axial, lateral, and angular movements with utmost ease. The dual-sphere configuration ensures optimal stress distribution, minimizing the risk of fatigue and premature failure. Furthermore, the unique design of the Double Sphere Rubber Joint effectively dampens vibrations, reducing noise levels and enhancing the overall efficiency of the system.

Our commitment to excellence is reflected in the rigorous testing and quality control measures that each Double Sphere Rubber Joint undergoes. We adhere to the highest industry standards, ensuring that our product meets and exceeds customer expectations. Additionally, our team of experienced professionals continuously strives to innovate and improve our offerings, guaranteeing that you receive a product that is at the forefront of technological advancements.

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".

Main Products

Application

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.
