Abstract:
1. A large scale cleaning plug adaptable to be placed within an interior passageway of a tubular system having a large diameter interior passageway for containing a fluid that may only partially fill the interior of the tubular system, the plug comprising: a generally conically shaped element having a first end and an opposite second end; said first end and said second end having a width selected to fit within the interior passageway of the tubular system; the first end having a width less than the diameter of the interior passageway of the tubular system; a frame body formed with the first end to maintain the first end in an open position permitting fluid flow into the first end of the conical element; the frame body being substantially rigid during cleaning operations; securing means connected to the conical element in proximity to the first end for controllably securing the conical element in desired positions within the interior passageway; and, a nozzle assembly mounted with the second end of the conical element; said nozzle assembly having a plurality of nozzle bodies extending from a plate preventing appreciable fluid flow therethrough as the fluid flows relative to the first end of the conical element and toward the second end and permitting a desired fluid flow of the tubular system fluid through an exit opening of the nozzle bodies; whereby sediment deposits located in the interior passageway in a direction of the fluid flow after the cleaning plug may be stirred without fully flooding the interior passageway of the tubular system ahead of the first end of the cleaning plug.
