NBR Double Sphere Rubber Expansion Joint Ansi Double Sphere Rubber Connectors

Double Sphere Rubber Connectors are flexible piping components designed with two spherical rubber bellows to provide enhanced multi-directional movement absorption (axial, lateral, and angular), vibration damping, and noise reduction in piping systems. Constructed from materials like EPDM or Neoprene rubber and reinforced with steel flanges, these connectors effectively compensate for thermal expansion, misalignment, and mechanical stresses, making them ideal for applications in HVAC, industrial pipelines, water supply, and wastewater treatment. Their dual-sphere design offers superior flexibility and stress distribution compared to single-sphere alternatives, ensuring reliable performance under varying pressures and temperatures.

Double Sphere Rubber Connectors 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:

• Reduce mechanical noise
• Compensate for eccentricity
• 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 Connectors 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 Connectors 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.
