6 Inch PN25 Single Sphere Flexible Rubber Expansion Joint
Flexible rubber expansion joint consists of rubber body and metal flanges or screw thread, which is used in metal pipe system for vibration isolation, reducing noise and displacement compensation. The flexible rubber expansion joint consists of inner layer rubber, reinforcing layer with polyester cord fabric and outside layer rubber with compounded rubber pipeline. flexible rubber expansion joint can choose any kind of inner layer rubber material and outer material, such as IIR, CR, EPDM, NR, NBR and so on. The external and internal layers of rubber material can be different. But skeleton layer of rubber joint are produced by polyester fabric and enhancement layer has a steel wire ring. Flange material is also diverse, common material is like Q235 SS304 and SS316.
Performance characteristics
1. Small volume, light weight, good elasticity and convenient equipment repair;
2. Lateral, axial and angular displacement can occur, and it is not bound by the non centering of pipeline and non parallel flange.
3. With the increase of temperature, the flexible rubber joint will expand and contract;
4. It can reduce the noise transmitted by the structure and has strong vibration absorption ability;
5. According to different scenes, the use of different rubber materials can more effectively prevent the corrosion of corrosive media on the inner wall of the rubber joint, and improve the service life.

Note: 1. Special requirements can be customized according to the user's drawings. The flange standard is GB / t9115.1-2000. A variety of flange standards (GB, JB, Hg, CB, ANSI, DIN, BSEN, NF, en, JIS, ISO, etc.) can be selected for production. Rubber spheres can be used as natural rubber, EPDM, chloroprene rubber, butyl rubber, butadiene green rubber, fluororubber, etc.2. When the suspended water supply uses products above DN200, the pipeline must have fixed support or fixed bracket, otherwise the product should be installed with anti pull off device.
