Decanter centrifuges and associated acceleration pipes and methods are provided. In accordance with an example, an acceleration pipe for use with a decanter centrifuge including a feed pipe and a screw conveyor having an acceleration chamber includes an acceleration pipe body adapted to be coupled to and rotate with the screw conveyor. The acceleration pipe body includes an acceleration pipe inlet and an acceleration pipe outlet. The acceleration pipe body defines an acceleration pipe flow path extending between the acceleration pipe inlet and the acceleration pipe outlet. The acceleration pipe body is adapted to receive a suspension at the acceleration pipe inlet from the feed pipe and to rotate the suspension, based on a corresponding rotation of the screw conveyor, prior to the suspension exiting the acceleration pipe outlet and being received by the acceleration chamber of the screw conveyor.
