DN100 EPDM Double Sphere Rubber Flexible of Floating Flange Rubber Expansion Joint
Flange rubber expansion joint is a critical component in piping systems, providing flexibility, durability, and reliability in various industrial and commercial applications. Its ability to absorb thermal expansion, vibration, and noise makes it an essential element in ensuring the smooth and efficient operation of piping systems. Ensure proper alignment and tightness of the joint during installation to prevent leaks and ensure optimal performance. Regularly inspect the joint for signs of wear, cracking, or corrosion, and replace as necessary to maintain system integrity and safety.
Performance characteristics of Flange Rubber Expansion Joint
Flange 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, flange rubber expansion joint 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.

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