NHFLEX-B TYPE NBR JIS10K Flanged Rubber Expansion Joint for Petrochemical Industries
The NBR JIS10K Flanged Rubber Expansion Joint is specially designed for use in petrochemical and oil-related piping systems where resistance to oil, fuel, and hydrocarbons is critical. Manufactured from high-quality NBR (Nitrile Butadiene Rubber) and fitted with JIS 10K standard flanges, this expansion joint provides reliable movement compensation, vibration isolation, and leak-free performance under demanding industrial conditions.
Characteristics:
1. Oil & Hydrocarbon Resistance
NBR rubber offers excellent resistance to petroleum products, fuels, lubricating oils, and many chemicals commonly found in petrochemical processes.
2. JIS 10K Standard Flanged Connection
Ensures precise fit, secure sealing, and full compatibility with Japanese standard piping systems widely used in petrochemical plants.
3. Effective Movement Compensation
Absorbs axial, lateral, and angular pipe movement caused by thermal expansion, pressure fluctuation, and equipment vibration.
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.
Standard Specification:
| Max.Working Pressure | 2.5Mpa | |||||
| Operating Temperature | -20ºC-100ºC | |||||
| Vacuum KPa (mmHg) | 44.9(350) | |||||
| Applicable Media | Sea Water, Drinking Water, etc. | |||||
| Flange Standard | DIN, JIS, GOST, ANSI, etc. | |||||

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.
