RUBBER
EXPANSION JOINTS

In order to offer a complete product range for our customers, we also design and supply rubber expansion joints. As our core competence is the design and manufacture of steel expansion joints, we have formed close partnerships with experienced and skilled manufacturers of rubber expansion joints. This ensures that our customers derive the same benefits from our rubber expansion joints as from our steel expansion joints.

A rubber compensator is a flexible unit that is manufactured from natural or synthetic elastomers or fluoroplastics and, if necessary, a reinforcement of the bellow (steel, nylon or aramid) is added. Rubber expansion joints are the perfect solution for pipe systems to absorb movements, vibrations or noise, resulting in the significantly prolonged service life of the pipe work and connected equipment.

Large standard range of high quality rubber expansion joints:
DN 20-3000 and in larger sizes up to DN 5000 or more on request.
The complete range can be seen in our data sheets.

What restraints are available for Rubber expansion joints?

Under pressure the compensator reacts in a positive axial direction (effective surface x operating pressure). If a rubber expansion joint is installed without restraints these movements are absorbed in the closest fixed points. Movements and forces can be absorbed by designing the compensator with restraints. The advantages of restraints are:

• The rubber element is prevented from breaking out of the flanges.
• Movements and forces are passed on to guides and anchor points.
• Lateral and angular movements or vibrations are absorbed.
