NBR double sphere rubber expansion joint is a type of rubber expansion joint, and its main rubber part is made of NBR (nitrile rubber) material.

Features

1.Oil resistance:

NBR rubber has excellent oil resistance and can maintain stable performance in oil medium environments.

2.Wear resistance:

The rubber part of NBR materials usually has good wear resistance and can resist friction and wear caused by fluid flow.

3.Weather resistance:

NBR rubber has a certain degree of weather resistance and can resist the influence of natural environments such as sunlight and rain.

4.Good sealing performance:

The dual sphere design provides good sealing performance, which helps prevent fluid leakage.

5.Absorbing vibration and noise:

Suitable for pipeline systems that require vibration absorption and noise reduction.

6.Easy to install and maintain:

usually designed to be easy to install and maintain, with a certain degree of flexibility.

Application scope

NBR double sphere rubber expansion joints are widely used in the following fields:

1.Petrochemical:

Suitable for pipeline systems in oil media, such as petrochemical plants.

2.Pharmaceutical industry:

Applied in the pharmaceutical industry where it is necessary to prevent the impact of oil media on pipeline systems.

3.Energy field:

Used for energy equipment and pipeline systems, such as heating pipelines.

4.Industrial pipeline: In various pipeline systems in industrial production, it is used to absorb thermal expansion, contraction, and vibration.

Advantages

1.Strong oil resistance, suitable for oil medium environments.

2.Good wear resistance, able to resist friction and wear.

3.Good sealing performance to prevent fluid leakage.

4.Absorb vibration and noise, protect pipelines and equipment.

Disadvantages

1.The temperature range is limited and may not be suitable for extreme high or low temperature environments.

2.It may not be suitable in some special chemical media and materials need to be selected according to specific circumstances.

Overall, NBR double sphere rubber expansion joints can provide reliable pipeline compensation and protection functions in specific environments, but specific industrial application requirements and environmental conditions need to be considered when selecting.
