The KOREMA® service: For reliable expansion joints

• Temperature:
  Fabric expansion joints are sensitive to both heat and cold. At high temperatures, they become brittle and lose their flexibility.
  At low temperatures, the elastomers (rubber coating) become hard, which can lead to cracks or fractures.
• Chemical resistance:
  Fabric expansion joints can also react to certain chemicals. Aggressive media can attack the surfaces of the expansion joints and thus shorten their service life.
• Mechanical load:
  If the pressure on the expansion joints is too high, they can deform or even burst. Excessive tensile forces can overstretch the material, which can also lead to damage.
• Bending and torsional stress:
  Frequent bending can lead to material fatigue and cracks. Rotational movements that exceed specified limits can also cause damage.
• Abrasive media:
  Media with solid particles or abrasive properties can wear the inner surfaces of fabric expansion joints. We therefore always recommend using baffle plates.
• Ageing:
  The expansion joints can exhibit material fatigue due to continuous loads and environmental influences such as UV radiation.

To ensure that the fabric expansion joints last as long as possible, it is essential that the installation instructions are followed.
Appropriate protective measures should be taken in the event of aggressive environmental influences. Regular inspection and maintenance also helps to detect damage and wear in good time.
