Elastomer Expansion Joints
Frenzelit elastomer expansion joints for aggressive media are made from highly flexible materials with excellent resistance. The extraordinary properties of these base materials are ideal for the very high demands in gas cleaning plants.
- Excellent mechanical stability against vibrations
- Very good resistance to deformation
- Resistance to SO2, SO3, H2SO4 and many other aggressive media
- Long-term temperature up to 204 °C depending on material
- Good low temperature resistance
- Nekal-tight in clamping and bellow area
- Installation of baffles not required
- Ideal for saturated and moist gases
Elastomer materials
The expansion joint thickness with elastomer can vary from 3.5 mm, 4.5 mm to 6 mm depending on the requirements; ideal for abrasive media with dust exposure and vibrations. Carrier fabrics made from isoGLAS®, isoTHERM® or novatex® (glass, aramid/glass-fabric blend) from our own in-house production and stainless steel mesh are vulcanized into the elastomers to provide reinforcement against extreme pressure and tensile loads. Two different inserts can be combined in expansion joints with thicknesses of 4.5 and 6 mm, depending on the requirements.
In addition to the ISO certifications, leading manufacturers of expansion joints established the Quality Association for Fabric Expansion Joints (RAL-Gütegemeinschaft). The quality assurance body develops standards for the production and use of flexible (fabric) expansion joints. These RAL GZ-719 Quality Assurance standards are published as “Technical Information” (please see documents and download area) and are recognized by the industry and inspection agencies. The members of this association are also audited for compliance with these standards on a regular basis by independent certification bodies such as TÜV. Frenzelit expansion joints meet these standards and are approved to carry the RAL quality mark. This guarantees that our customers get the best possible quality available on the market today.
