Standard Screw Flights | Standard‑Pitch Auger Screw Conveyor Flights Manufacturer

BOOTEC‑Standard Screw Flights, high‑precision auger screw flights as core spare parts for screw conveyors in bulk material handling

Standard screw flights, also known as standard‑pitch screw flights or screw conveyor flights, are the key helical working component of auger conveyors. Mounted onto the screw shaft for screw conveyors, they rotate to push powder, granular, fibrous and small‑lump bulk materials inside U‑trough or tubular conveyor housings. BOOTEC acts as a reliable standard screw flights manufacturer and supplier, providing both new‑production and replacement auger flights for screw conveyor for original equipment build‑up and field maintenance.

We supply two main constructions: continuous screw flights (helicoid flights) cold‑rolled as one‑piece helix, and sectional screw flights fabricated in individual segments for heavy‑duty and large‑diameter applications. Our standard‑pitch design features pitch equal to screw outer diameter, the most universal configuration for general conveying conditions. Material options cover carbon steel, stainless steel and wear‑resistant alloy steel, adaptable to abrasive, corrosive or moderate‑temperature working media. Short‑pitch and double‑flight versions are also available upon special request.

These screw conveyor flights are widely deployed across bulk solids handling industries. Typical applications include pulp and paper mill for wood chips, bark and fibrous pulp rejects; waste‑to‑energy plant and biomass power plant for fly ash, bottom ash and combustion residues. They fit for standard screw conveyors as well as cooling screw conveyor systems, serving as critical screw conveyor spare parts.

Key Features

• Standard‑pitch helical profile; available in continuous or sectional screw‑flight structures
• Multiple material grades: carbon steel, stainless steel, wear‑resistant alloy steel
• Strict dimensional tolerance for smooth welding and assembly onto screw shaft
• Stable conveying performance for powder, granules, chips and fibrous bulk materials
• Offered as OEM auger screw flights, original components or wear replacement parts
• Each flight undergoes dimension inspection before delivery to guarantee consistent running performance
