NBR Double Sphere Rubber Compensator Ansi Flanged Rubber Expansion Joint
NBR double sphere rubber compensator consist of double-ball rubber spheres and flanges. The rubber ball part can be made of different materials, such as natural rubber, EPDM and NBR, to adapt to different media and environmental conditions. The flange part is usually made of national standard Q235 carbon steel or 304 stainless steel to ensure good corrosion resistance and mechanical properties. NBR double sphere rubber compensator are widely used in a variety of industrial piping systems, especially in the need for vibration and noise reduction, compensation displacement occasions.
Performance characteristics of Double Sphere Rubber Compensator
NBR double sphere rubber compensator offer ultra-high performance, reliability and longevity, thus improving plant safety and the mechanical integrity of equipment. Due to the insertion of specially designed products in rigid piping systems, Joint expansion are able to:
1. Reduce mechanical noise
2. Compensate for eccentricity
3. Eliminate electrolysis between dissimilar metals

Note: 1. The special requirements of flanged 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 flanged expansion joint can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene rubber, fluororubber, etc. when the flanged expansion joint above DN200 is used for suspension water supply, the pipeline must have fixed support or fixed support, otherwise the flanged expansion joint shall be installed with anti falling device.

Do you know how is a Double Sphere Rubber Compensator made? Let's see with JINGNING.
It is very important to select the appropriate joint expansion, to understand the compatibility of the medium and the selected material of the joint expansion, the range of full temperature, full pressure and full vacuum, the amount of movement required, and the size between the pipe flanges. With this information, JINGNING application engineers can help determine the ideal joint expansion for any application.
Double Sphere Rubber Compensator application
NBR double sphere rubber compensator are widely used in various pipeline systems, such as the connection of joint expansion with pumps and valves, fire-fighting equipment and pipelines with large vibration. Pipes with frequent changes of heat and cold. Double sphere rubber expansion joint 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 NBR double sphere rubber compensator has high wear resistance, joint expansion is also suitable for all industries of granular and powdery and gas low temperature.
