QF Long Radius Elbow

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

Quick-Fit^® Long Radius Elbows have rolled ends for use with Quick-Fit Clamps, allowing quick assembly / disassembly and relocation.

Long Radius Nordfab QF® elbows, also referred to as Bends, are available in 90°, 60°, 45°, and 30° with radiuses of 1.5 or 2.5. Standard elbows are also available with radiuses of 1.0 or 1.5.

Galvanized QF Elbows in sizes 3″-7″ are press formed halves stitch welded together. QF elbows in sizes 8″-24″ are segmented (gored). Stainless steel QF Elbows sizes 3″-6″ are tubed.

Elbows in heavier gauges can be supplied in solid welded construction at an additional cost. For highly abrasive applications or placement in a high wear area within the duct line, Nordfab long radius elbows in 14 gauge steel construction or 12 gauge may be the solution to reduce the frequency and cost of replacing worn-through elbows.

Available in Galvanized and 304SS (as shown below) or optional 316SS or carbon steel
Available with flanged ends in diameters up to 72", and other various end types
Optional gauges 20, 18, 16, 14, 12 and 10
