Adapt Quick-Fit® Ducting to Existing Flanged Ductwork
Nordfab® Quick-Fit ducting products can be easily integrated with existing flanged duct systems using an Angle Flange Adapter. Norfab Angle Flange Adapters feature a QF rolled edge on one end and an angle ring on the other as standard.
We also offer Flat Flange ends that can be customized to meet your hole pattern requirements.
Nordfab Duct Pipe in diameters larger than 24"
QF ducting is available in diameters of up to 24".
For larger duct requirements, we carry Nordfab flanged duct pipe in diameters of up to 40".
Flanged duct pipe is constructed from sheet blanks that are 78.75" long and rolled with a longitudinal lock-form seam.
As seen above, an industry standard angle flange made from angle bar stock rolled on edge is placed on the end of the duct and secured using a Van Stone lip connection.
The loose flange allows easy matchup to holes on existing flanges.
The connection of two flanged pipes is illustrated in the example below.
