Abstract
An apparatus for straightening fluid flow in a conduit or pipeline, such as an irrigation pipeline, resides in an integral assembly of a conical fluid flow displacement member effective to substantially lineralize the velocity profile of fluid flowing through the pipeline and a plurality of circumferentially spaced vanes extending longitudinally and radially of the conical member and effective to mitigate swirl and eccentric velocity profiles in the flowing fluid. The conical member consists simply of a single cone that is centered in the pipeline by the vanes. A bolt extending through the wall of the pipe and threaded into a nut on a vane secures the straightener in the line.
