ANSI, DIN, JIS Flanged Rubber Expansion Joint Double Sphere Rubber Flexible
Flanged rubber expansion joints are flexible connectors made of natural rubber or synthetic elastomers, steel rings and fabric. Where necessary, metal reinforcements relieve stresses in the piping system due to heat, mechanical vibration and/or movement. Flanged rubber expansion joints relieve stresses caused by thermal expansion and cold contraction of piping. Piping systems are always moving due to changes in ambient temperature, differences in temperature and composition of the materials handled. Flanged rubber expansion joints absorb this movement, eliminating the risk of bending or opening, resulting in high replacement costs.
Performance characteristics of Flanged Rubber Expansion Joint
Flanged 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.

Flanged Rubber Expansion Joint production Flow
Do you know how is a Flanged 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.
Flanged Rubber Expansion Joint application
Flanged 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.
