Sectional Screw Flights

Sectional / Segmented Auger Flights

FEATURES

  • A proprietary process coming into its own when material type, material thickness, big diameters, hard controlled special gauge are considerations and cannot be accomplished by conventional continuous rolled forming process
  • A single pitch construction with consistent cross sectional thickness between inner and outer edges. Every screw flight section is formed accurately up to the customer’s size.
  • A wide range of sizes up to 2000 mm in diameter, 40 mm in thickness, and 1500 mm in pitch are available
  • Ribbon, Tapered and Variable Pitch Flights are available on application. Flights can also be hard faced or coated with wear protection materials
  • High precision, with no minimum order quantity requirement and customized size can be met.

 

MATERIALS

Carbon Steel, Low Alloy Steel, Wear Resistant Steel, Stainless Steel, etc.

 

SPECIFICATIONS
