Flanged Branch 12ga

Flanged Branch 12ga

Nordfab manufactures ducting for use in dust, mist, and fume collection systems.

Our 12 gauge Flanged Branches (sometimes called “wyes” or “laterals”) are provided with industry-standard Angle Flanges on both ends, the flanges are loosley retained via a vanstone lip so that bolt holes can easily be aligned with those on existing flanged connections.

12 Gauge Branches have leak-free, solid welded seams, which make them ideal for applications where material conveyed in the dust collection line is highly abrasive or for areas in the duct line where there is excessive wear.

  • Standard 30º, available with 45° angle
  • When ordering, specify A, B, C.A – C ≥ C – B
  • Use formula above to determine if a reducer is needed at C end.
  • Use the following formula to determine length: L = C X 2 + 15"
  • Available in galvanized steel or carbon steel
  • Diameters up to 72"
  • Flange gaskets available
  • If welded flanges are required, clocking must be specified. Flanges with custom hole patterns available

Contact Nordfab or your local Nordfab dealer for assistance with optional end types, larger sizes, and material / gauge options.
