Product Description

EPDM Single Sphere Rubber Expansion Joint Flange Type Small Volume


Single Sphere Rubber Expansion Joints are also called rubber joints, rubber flexible joints, soft joints, shock absorbers, pipeline shock absorbers, shock-absorbing throats, etc. They are a kind of high elasticity, high air tightness, medium resistance and weather resistance. Pipe joints.


Performance characteristics of Single Sphere Rubber Expansion Joint


1. It has the advantages of small volume, light weight, good ductility, convenient installation and maintenance, etc.

2. Installation can cause horizontal, radial and angular offset, which is not limited by the uneven center of pipe plug and flange surface.

3. When working, it can reduce the noise transmitted by the structure and has strong damping capacity.

Note: The special requirements of bellows expansion joint 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 axial expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the axial expansion joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the axial expansion joint shall be installed with anti falling device.

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


Bellows expansion joint advantage


1. Ex factory price of axial expansion joint.

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

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

4. The mold has a variety of specifications and supports customization and OEM.

5. Provide samples free of charge.

6. Large inventory.


Bellows expansion joint application


Bellows expansion joints are widely used in various pipeline systems, such as the connection between axial expansion joints and pumps, valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes in cold and heat. It is mainly used for the lifting and transportation of remote water and sewage, water supply and cooling circulating water of thermal power plants, pipeline transportation in metallurgical industry, condensate water, pipeline transportation in chemical industry, cooling and dilution in petrochemical industry, and flexible connection between long-distance and short-distance pipelines in other industries. Because the axial expansion joint has high wear resistance, it is also suitable for all particle, powder and gas low-temperature industries.
