Pipeline Expansion Joints

1) Product Performance of Single Sphere Pipeline Expansion Joints 

LIWEI Single Sphere Pipeline Expansion Joints GJQ(X)-DF are designed for piping systems to absorb pipe movements, relieve stress, reduce system noise/vibration, and compensate for misalignment/offset and to protect rotating mechanical equipment against start-up surge forces. 

Single Sphere Pipeline Expansion Joints GJQ(X)-DF  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 Sphere Pipeline Expansion Joints 

Equipped with the excellent comprehensive performances of Expansion Joint Rubber, LIWEI Single Sphere Pipeline Expansion Joints GJQ(X)-DF  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. 

3) Features and Benefits of  Single Sphere Pipeline Expansion Joints 

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 

10, Solid galvanized steel floating flanges speed the installation time 

11, High tensile aircraft cable is embedded in the raised face rubber ends to prevent pull out and avoids the sharp cutting edge of solid steel rings 

12, No gaskets required; integrally rubber flanged design, no gaskets required, DIN PN10/16 drilling standard, other flange drilling available, including ANSI 150lb/300 lb, BS, and JIS
