Product Description

DN125 Single Sphere EPDM Rubber Compensator Expansion Joint


Rubber compensator is commonly known as rubber joint. Rubber compensator is widely used in water, electricity, chemical industry and ship mooring system. The rubber compensator can be automatically extended with the natural change of weather during use. The structural material of the rubber compensator is nylon cord fabric, and the inner and outer surfaces are made of high strength aging resistant polar rubber. In order to prevent the natural shrinkage and reduce the aging fracture of rubber compensator in long-term use, steel wire is used for multiple protection.


Performance characteristics of flexible joint pipe


1. The rubber compensator has the advantages of small volume, light weight, good elasticity and convenient installation and maintenance.

2. After installation, the rubber compensator can absorb the lateral, axial and angular displacement caused by the vibration of the pipeline, and is not limited by the non concentric pipeline and non parallel flange.

3. After the rubber compensator is installed, the noise caused by the vibration of the pipeline water pump can be reduced, and the vibration absorption ability is strong.

4. The inner seamless high pressure rubber compensator can effectively prevent the corrosive medium from eroding the inner wall of the rubber joint in the high temperature resistant, acid alkali resistant and oil resistant pipeline, and improve the service life.

Note: 1. The special requirements of rubber compensator can be customized according to user's drawing. Flange standard is GB / t9115.1-2000. Various flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. The rubber ball of rubber compensator can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the rubber compensator above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the rubber compensator shall be installed with anti falling device.

It is very important to know the compatibility between the medium of rubber compensator and the selected rubber compensator material, the range of full temperature, full pressure and full vacuum, the required movement of rubber compensator, and the size between pipe flanges when selecting the appropriate rubber compensator. With this information, Jingning application engineers can help determine the ideal rubber compensator for any application.


Rubber compensator advantage


1. Factory price of rubber compensator.

2. 16 years of manufacturing experience, 5 years of export experience.

3. Strict quality inspection, the quality far exceeds the industry standard.

4. Rubber compensator mold has a variety of specifications, support customization, OEM.

5. Provide free samples of rubber compensator.

6. Rubber compensator are in large stock.


Rubber compensator application


Rubber compensators are widely used in various pipeline systems, such as the connection of Rubber compensators with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold. Rubber compensator is mainly used for remote water and sewage lifting and transportation, water supply and cooling circulating water of thermal power plant, pipeline transportation of metallurgical industry, condensate water, chemical industry, cooling and dilution of petrochemical industry, and flexible connection between long and short distance pipelines in other industries. Because the rubber compensator has high wear resistance, Rubber compensator is also suitable for all industries of granular and powdery and gas low temperature.
