NBR Double Sphere Rubber Expansion Joint Ansi Double Sphere Rubber Expansion Joint
Double sphere rubber expansion joint with NBR rubber features two spherical rubber bellows interconnected by a metal flange or core. The bellows are made of high-quality NBR rubber, which is known for its excellent oil and fuel resistance, as well as its ability to withstand moderate temperatures and pressures. The metal flange or core provides structural support and ensures a secure connection to the piping system.
Performance characteristics of Double Sphere Rubber Expansion Joint
Double sphere rubber expansion joint 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.

Double Sphere Rubber Expansion Joint production Flow
Do you know how is a Double Sphere Rubber Expansion Joint 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 Expansion Joint application
Double sphere rubber expansion joint 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 the double sphere rubber expansion joint has high wear resistance, joint expansion is also suitable for all industries of granular and powdery and gas low temperature.
