Abstract: In one aspect, centrifuge feed pipes are described herein having design and architecture for mitigating wear during centrifuging operations. In some embodiments, a centrifuge feed pipe comprises a feed material inlet, a feed material outlet, and a conduit body extending along an axis between the feed material inlet and outlet, the conduit body having a variable inner diameter at one or more locations along the axis. In being variable, the inner diameter is not uniform over all radial positions of the inner diameter.
