Fabric Expansion Joints
DEKOMTE supplies quality fabric expansion joints and many different high quality materials are used for this. In principle, fabric expansion joints are best for gaseous media, such as air, exhaust gases or solvent fumes, for operation below the dew point (also with a high concentration of acids) and for abrasive exhaust gases (e.g. containing coal dust).
Its fire-proof expansion joints at ducts through walls and ceilings with fire-protection requirements can withstand flames for 90 minutes and more in accordance with DIN 4102. Only quality processing appropriate to the material being used can guarantee the highest reliability. For example, the nuclear power sector has strict regulatory requirements; DEKOMTE has the required certificates for radiation resistant materials. If required, DEKOMTE can offer project planning for expansion joints including selection of components and optimum design as a specialized engineering service.
Furthermore, the proven DEKOMTE customer service is always available. It will help you in case of unexpected problems as well as with the rapid replacement of complete expansion joints.
Geometry
DEKOMTE fabric expansion joints can be supplied in any geometry as well as in any dimension required. Below you can find an overview of some common expansion joints arrangements.
General
DEKOMTE fabric expansion joints are always manufactured without asbestos, they are used to compensate for axial, angular and lateral expansion in pipelines with superimposed movements also being permissible. Due to the good flexibility of DEKOMTE fabric expansion joints, the reaction force common for metal expansion joints can be ignored during planning. Special designs are available for vibrations and oscillations.
These compensating elements are suitable for gaseous media, such as air, flue gas, exhaust gases and solvent fumes, for operation below the dew point (also with a high percentage of acids) and for abrasive exhaust gases (e.g. containing coal or cement dust).
Optionally, fire-proof sealing tapes are available as flexible seals for any type of building joint and fire-proof expansion joints are available as flexible seals for ducts with non-flammable pipes through walls and ceilings with fire protection requirements.
Materials
Multilayer construction using temperature and corrosion resistant insulating fabrics, also gas-tight films/ foils of PTFE, Inconel, lead, aluminium, etc. can be supplied for special cases. External installations are abrasion resistant and non-ageing.
