Screw Flight Calculator will give you handy Calculation of Screw Flight development. It will give you Flat pattern Size for Cutting Blank plate for development or fabrication of Screw flight. This app is very useful for those who are working in the field of Screw Conveyor or Ribbon Blender fabrication. In this App Input is Required Outside & Inside Diameter of Screw, pitch of flight, material thickness & specific gravity of material of Construction such as carbon steel, Stainless steel,Copper, Brass or Bronze material. This app Gives Output as Development Outside Diameter of raw Plate Circle & Inside Diameter of Circle so that it will be perfectly fit with shaft or pipe on which it will be going to weld after twisting of raw plate. It app includes addition Element of Radial Cut Required for flight development, but it is advisable to use full circle for Cutting. This app is also for those who are working in the field of fabrication of Pressure vessel, Heat ex-changer, Storage Tank, Agitator & Mixer and any other process equipment. this app also calculate the weight of material after cutting according to development.
