Pumping Surges Single Sphere Rubber Expansion Joint PN6 PN10 Working Pressure
Flexible rubber expansion joint treatment couplings for pipes
JINGNING Expansion Joints offer superior performance, reliability, and service life, resulting in improved plant safety and increased mechanical integrity of equipment. As specifically engineered products that are inserted in a rigid piping system, JINGNING Rubber Expansion Joints will:
- Absorb movement
- Improve thermal stability
- Relieve system strain due to thermal change, load stress, pumping surges, wear of settling
- Reduce mechanical noise
- Compensate for misalignment
- Eliminate electrolysis between dissimilar metals
All of our expansion joints carry safety ratings that exceed product specifications in areas such as pressure and movement. Non-metallic expansion joints and flexible couplings are ideally suited for a wide variety of industries.

NOTES:
Dimensions are expressed in mm, and subjected to manufacturing tolerances. Data can be altered without notice by our Design Department for the product benefit.
* The stated movements are solely valid with the joint subject to a single movement direction. Values are proportionally reduced along with the movement combination.* Given tolerance installed and movements allowed are valid for rubber bellows. For bellows with PTFE sleeve, values must be reduced by 1/2.
* Increasing temperatures reduce the permissible movements capacity and number of cycles. Dimensions are expressed in mm
The joints may consist entirely of the one type of rubber or a combination with one type of rubber as the inner ply and a different rubber as the outer cover.
