Abstract:
1. A large scale cleaning plug system adaptable to be placed within an interior passageway of a tubular system, the plug comprising: a skeletal frame structure adapted to support an outer skin member for containing and directing a fluid through an interior central passageway formed in the skeletal frame structure; the skeletal frame structure having a first end and an opposing second end; the first end being upstream of the second end in relation to a fluid flow path through the interior passageway of the tubular system during operation of the large scale cleaning plug and the first end formed having an opening therethrough for the passage of the fluid; the first end and the second end of the skeletal frame structure each having a width less than a width of the interior passageway of the tubular system; the skeletal frame structure formed having a middle segment comprising a generally frustoconical shaped bottom element having a downstream first end and a truncated opposite second end; said first end and said second end of the middle segment having a width selected to fit within the interior passageway of the tubular system; securing means connected to the skeletal frame structure in proximity to the first end for controllably securing the skeletal frame structure in desired positions within the interior passageway of the tubular system; and, the second end of the skeletal frame structure formed having a rear segment supporting at least one nozzle assembly; said nozzle assembly having at least one nozzle body extending from a plate preventing appreciable fluid flow therethrough and permitting a desired fluid flow through an exit opening of the nozzle bodies.
