Flanged Expansion Joint Ansi Double Sphere Bellow System
A Flanged Expansion Joint with ANSI Double Sphere Bellow System is a specialized piping component designed to accommodate thermal expansion, contraction, vibrations, and misalignments in piping systems. It features a double-sphere bellow structure that provides enhanced flexibility and movement absorption capabilities. The flanged ends of the expansion joint conform to ANSI (American National Standards Institute) standards, ensuring compatibility and ease of installation with other ANSI-compliant piping components. This system effectively reduces stress on the piping network, preventing damage and ensuring the reliable and long-term operation of the overall piping system.
Performance Characteristics of Double Sphere Bellow System
- Reduce mechanical noise
- Compensate for eccentricity
- Eliminate electrolysis between dissimilar metals

Note: 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 Bellow System Details
Double Sphere Bellow System Production Flow
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 Bellow System Applications
Double Sphere Bellow System 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.
