Installation Method
  • Clamp bar fixing on duct angles
Dimensions
  • For round and rectangular duct cross sections
Installation length
  • = Installation gap + 2x fixing width
  • Individually according to customer specifications
Fixing Width
  • Depends on pressure and nominal diameter between 60 and 100 mm
Media Temperature
  • Depending on the height of the duct angle and duct lining, suitable for up to 1200 °C
Pressure
  • Up to ±0.25 bar
  • Higher pressures on request
Movement

For axial, lateral and angular movements

Benchmarks :

  • axial compression = approx. 0.25 x installation gap
  • axial extension = approx. 0.25 x installation gap
  • lateral displacement = approx. 0.20 x installation gap

In the event of axial extension and simultaneous lateral displacement, movements are reduced. For large lateral movements, we recommend presetting the duct against the direction of movement.
