Abstract: Methods and apparatus for use within a production pipeline or other flowbore to reduce fluid pressure and regulate fluid flow while minimizing erosion effects caused by particulate matter in the fluid, wherein varying geometries with respect to multiple components within a choke valve are utilized to effectuate multiple changes in fluid flow direction, causing a fluid pressure drop at each directional change.

Abstract: Flow enhancing restrictors are located within a fluid conduit to provide pressure reduction and flow enhancement. The restrictors may be used in combination with a conventional choke valve or as a stand-alone pressure reduction means. Alternative exemplary embodiments for flow enhancers are described. Each of the flow enhancers has a generally cylindrical base with at least one fluid passage disposed therethrough. Each of the flow enhancers also provides a dome that projects upwardly from the center of the base to assist in directing fluid flow and receiving the abrasive forces associated with the fluid.
