Abstract: Material flow modifiers as disclosed herein overcome drawbacks associated with known adverse flow conditions (e.g., surface erosion, head losses, particulate drop-out, and the like) that arise from flow of certain types of materials (e.g., fluids, slurries, particulates, flowable aggregate, and the like) through a material flow conduit. Such material flow modifiers provide for flow of flowable material within a flow passage of a material flow conduit (e.g., a portion of a pipeline, tubing or the like) to have a rotational flow profile. Advantageously, the rotational flow profile centralizes flow toward the central portion of the flow passage, thereby reducing magnitude of laminar flow to overcome the aforementioned adverse flow conditions.

This method of construction usually may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume.
