Introduction
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.
