  • Patent number: 4216910
    Abstract: Pipes, coated with paraffin, scale or otherwise, are cleaned by internally spraying the pipe with a conic sheet of paraffin solvent or scale remover or other fluid. The reaction of the discharge of the sheet of fluid is the propelling force for advancing the nozzle through the opening. An axial jet of fluid clears the tube in front of the nozzle so that the nozzle can advance through the tube. The conic sheet is formed by a pair of sleeves around a mandrel, the sleeves meeting with correlative conic surfaces.
