Screw Conveyor Catalogue and Engineering Manual (1996)

In a screw conveyor, the screw is sized by its diameter, shaft size and length. For screws up to standard length, the pipe size is dependent on the shaft size and is schedule 40. The standard shaft/pipe combination is adequate to handle both the torque and deflection of a screw up to the standard length.
