Sectional Flights

       
 

 

Sectional flights are individual 360 degree sections of helices or flights formed from flat plate. These individual sections are then welded together to form continuous flights for conveyors, augers or any machine with a screw flight requirement. The individual flights being of a true-form in order to give a constant pitch angle, accurate fit to the shaft and flush joints. 

Augerflights is one of New Zealand's most experienced manufacturers of sectional helices and a flagship of the Marshall Group. We have solution for all of your flighting need. 

We specialise in forming sectional helices from a range of materials;

  • Mild steel
  • Stainless steel
  • Aluminium
  • Alloys
  • Abrasion Resistant Plates
  • Hardox 450
  • Bisalloy
  • High Tensile Steel
  • Sandwich Plates

What is True form Helix?

Accurate fit to shaft for efficient handling

Uniformity for weld procedure
Pitch angle - If pitch angle is not a uniform linear spiral, welding will require a variety of tracking adjustments to follow the non linear spiral
Helix flange perpendicular to shaft - a typical incorrect helix usually causes a variety of weld angles around the helix. This will affect both the positional requirements of the weld, and consistency of both throat and root of welding between helix and shaft

Helix internal edge parallel to shaft - the potential variability in the gap between the shaft and the edge of the inner helix edge. If not parallel, can result in a significant variation in the weld root and hence consistency and quality of weld

Therefore - A true pitch helix shall have;
Flange perpendicular to shaft and 
Uniform pitch angle
