Performance of rubber expansion joint

One Ball Rubber Bellows Flexible Joints  is a single sphere design with less length, the supply range is from 32mm to 3600mm, and design pressure can be 1.0MPa/1.6MPa/2.5MPa, which is always used where low cost or space limitation control. 

One Ball Rubber Bellows Flexible Joints  are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces.
