Water Pipe Single Sphere Rubber Expansion Joint Bellows Flex Connector
Single Sphere Rubber Expansion Joints have the characteristics of high pressure resistance, good elasticity, large displacement, balanced pipeline deviation, vibration absorption, noise reduction effect, and convenient installation.
Single Sphere Rubber Expansion Joint application
The Single Sphere Rubber Expansion Joint is widely used in various pipeline systems, such as the connection with pumps and valves, fire-fighting equipment and pipelines with large vibration, and pipelines with frequent changes in cold and heat. It is mainly used for the lifting and transportation of remote water and sewage, water supply and cooling circulating water of thermal power plants, pipeline transportation in metallurgical industry, condensate water, pipeline transportation in chemical industry, cooling and dilution in petrochemical industry.

Note: special requirements can be customized according to user drawings. The 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. Rubber balls can be used as natural rubber, EPDM, neoprene, butyl rubber, butadiene rubber, fluororubber, etc. When the flexible expansion joint above DN200 is used for suspended water supply, the pipeline must have fixed support or fixed support, otherwise the flexible expansion joint shall be equipped with anti falling device.
