LIWEI 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. 

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. 

2) Application Range of Single Arch Rubber Joint 

Equipped with the excellent comprehensive performances of flexible rubber joint, LIWEI One Ball Rubber Bellows Flexible Joints  can be used for lift and transportation of raw water and sewage, transportation of water supply, cooling cycle water of thermal power plant, condensate water of metallurgy industry and chemical materials of chemical industries, cooling and dilution of oil and chemical industries and flexible connection of other industries. LIWEI One Ball Rubber Bellows Flexible Joints  is also suitable to transport all grain and powder material and gas for its high abrasive resistance.  

3) Features and Benefits of Single Arch Rubber Joint 

1, Versatile hand-built construction. Made in China 

2, Absorbs directional movement 

3, Absorbs vibration, noise and shock 

4, Compensates for misalignment 

5, Wide flowing arch design

6, Virtually eliminates sediment buildup 

7, Economical fully molded construction 

8, High vacuum rating (up to 30" Hg) can be supplied for certain sizes 

9, Special grooved flange ring design, prevent rubber end pull out
