Contractors who design, build and install Air Conveying Systems to move materials like paper, fibers and cotton specialize in a niche industry of Sheet Metal Fabrication. Pneumatic systems that move materials instead of just air typically require that the piping has a welded longitudinal seam, because thickness of metal must be at least 18 gauge for a proper weld. These shops typically use 18 gauge and 16 gauge frequently. For the transverse connections, these shops often put Angle Iron Rings on the pipe and then Vanstone a right angle on each end by means of a Power Rotary Machine with 1/2″ Flanging Rolls.
- Rolled Carbon Steel Prepunched Angle Iron Rings are used in joining duct work together.
- We stock diameters 3″ thru 59″.
