ABSTRACT:
A device for use in a pipeline including a fluid conduit section constructed of a flexible material. The fluid conduit section has a first end, which includes a first mounting arrangement, and a second end, which includes a second mounting arrangement. The fluid conduit section also has a length defined between the first and second ends, an internal diameter, and a fluid passage therethrough to allow fluid to flow from the first to the second end. The device also includes a plurality of longitudinally extending vanes positioned within the fluid conduit section, wherein radially inner edges of the vanes are in direct contact with the radially inner edges of adjacent vanes, and radially outer edges of the vanes contact one of the first and second ends, but are separated from the internal diameter of a remainder of the fluid conduit section, such that a space is defined therebetween.
