Dn450 Ball Connector Epdm Double Flange Sphere Bellow Flexible Expansion Rubber Joint

There are lots of material selection based on usage area of double sphere rubber expansion joints.
Rubber expansion joints can absorb large movement in very short distance.
They provide all directional movement, such as axial, angular, lateral and torsional that may occur from external conditions. Also reduce wind, shock loading and seismic movements.

Advantages

Rubber spherical joints have a distinct advantage over metallic expansion joints for corrosive applications and installations requiring a high cycle life. The contour prevents sediment accumulation and creates less turbulence and pressure drop than spool joints. The seal eliminates any requirement for gaskets between mating flanges. Spheres may be installed on raised-face or flat-face flanges.

Applications areas
• Heating and cooling devices
• Materials handling technologies
• Water pipes
• Desalination plants
• Compressors
• Blowers and fans
• Cement industry
• Chemical industry

Material selection

Material selection of rubber expansion joints are very variable and depends on the pressure, temperature, fluid etc. parameters. The common materials are, EPDM, IIR, NBR, PTFE and combined with these materials depends of usage area. Also the inner tube and outer tube’s diameter can be different depends of design conditions.
