Flange design on rectangular ducts

  • Standard rectangular duct is delivered with flanges made of flange sheets and corners. Flange size is specified by the longer side of the section as follows:

Material

  • Standard duct materials include:
  • Galvanised sheet metal DX51D 275 MAC/NAC
  • Stainless steel AISI 304 (1.4301), AISI 304L (1.4307), AISI 316 (1.4401), AISI 316L (1.4404)

Rectangular 30°, 45°, 60°, 75°, 90° curve

OL A × B / α - R

  • A - cross section dimension
  • B - cross section dimension
  • α - curve angle [ ° ]
  • R - internal radius of curve

Length / wall thickness

  • < 800 / 0,6 mm
  • ≤ 1 500 / 0,8
  • > 1500 / 1,0 mm

Design

  • Crimped at flange joint.
  • Corrugated reinforcement standard on all ducts.
  • Leading plates are mounted as standard per to the table in the technical conditions.

Leading plates for rectangular and rectangular reducer curves

Dimension A1 is decisive instead of A for OLP reducer curves.
