Description

Can Be Customized For Pipe Ansi Double Sphere Expansion Joint Duct

A Double Sphere Expansion Joint Duct is a highly flexible piping component designed for ductwork systems, featuring two spherical bellows that enable multi-directional movement absorption—including axial, lateral, and angular displacements—while maintaining a leak-proof seal, thereby effectively compensating for thermal expansion, mechanical vibrations, and misalignments in applications such as HVAC, industrial ventilation, and exhaust systems, while reducing stress on connected equipment and ensuring reliable, long-term performance under varying operating conditions.


Performance characteristics of Double Sphere Expansion Joint Duct

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.

Do you know how is a Double Sphere Expansion Joint Duct made? Let's see with JINGNING.

Can Be Customized For Pipe Ansi Double Sphere Expansion Joint Duct

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 Expansion Joint Duct application

Double Sphere Expansion Joint Duct 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.
