Description

Product Description

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.

All of Jingning's rubber expansion joints safety ratings exceeding product specifications in such areas as pressure and movement.

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.* 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

About rubber materials

Flexible rubber joints can be manufactured from a range of elastomer materials including:

»Chloro Butyl »EPDM

»Hypalon »Natural

»Neoprene »Nitrile (Buna-N)
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.

We will select the appropriate rubber grade for your application from a wide variety of different blends depending on the composition of the medium and the operating temperature.
