Abstract:

Embodiments of an apparatus of the present invention generally include a filtration assembly having a louvered shroud circumferentially positioned around a perforated inner pipe, such that at least a substantial portion of the shroud's inner surface contacts and frictionally engages the outer surface of the inner pipe. Embodiments of a method of the present invention generally include spirally wrapping a substantially flat strip of louvered material around the inner pipe, wherein adjoining edges of the louvered material abut and are at least partially welded together, to provide the shrouded pipe. Other method embodiments generally include an inner pipe having a louvered shroud positioned there around being introduced to a device operable to, dynamically or statically, radially compress the shroud such that at least a substantial portion of the shroud's inner surface contacts and frictionally engages at least a substantial portion of the outer surface of the inner pipe.
