For pipe construction, you will need expansion joints – to absorb thermal expansion, to reduce vibration and noise.Our ‘JINGNING’ expansion joints have reliably performed these tasks since 2004.
An expansion joint is a specially engineered product inserted in a rigid
piping system to achieve one or more of the following:
» Absorb movement
» Relieve system strain due to thermal change, load stress, pumping surges, wear or settling
» Reduce mechanical noise
» Compensate for misalignment
» Eliminate electrolysis between dissimilar metals

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.Do you know how is a high quality rubber expansion joint made?Let's see with JINGNING.
