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.

DIMENSIONS

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.

ADVANTAGES

  • Optimum solution for narrow spaces, still able to absorb large movements due to the flexible Bellows
  • Absorbs axial-, lateral-, and angular movements
  • Reduces water shock
  • Safe, reliable, durable and maintenance free
  • Temperature-, chemical-, and corrosion resistant
  • Managing flexibility and pressure is optimised
  • Low spring rates
  • Vacuum and pressure proof
  • Can accommodate line misalignment
  • Sound deadening effects

CUSTOMISED SOLUTIONS

Staying true to our core competences we are also able to provide customised solutions within rubber expansion joints. As always we welcome challenging tasks, we will deliver the most effective solution from both the operational and economic perspective.

RESTRAINTS

Under pressure the compensator reacts in a positive axial direction (effective surface x operating pressure). If a compensator 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.
