Double bellow

Double spheres rubber expansion joint is made by rubber sheets wrapping around a bellows-shape mandrel with two spheres, and it is flexible unit installed in piping system to absorb vibrations and shock, relieve anchor stress, reduce noise, and compensate for misalignment.

Single Arch Rubber Expansion Joint provides vibration control, compensates for pipework misalignment, and allows for thermal expansion in abrasive slurry applications. The single-arch configuration increases the range of movement of the joint.
