Abstract
Pipes, tubes and the like, for example, in heat exchangers, can be cleaned internally using sonic energy, a relatively incompressible pig and a flushing liquid. The flushing liquid is supplied via a pressure outlet from a quick operating valve to one or more launchers for launching pigs. The launchers are mounted on either an x-y frame movable support or a rotary axis adapter and radially movable support for positioning the launchers with respect to the ends of the tubes to be cleaned.
Claims4
Apparatus for cleaning one or more tubes which comprises in combination a source of high pressure liquid and quick-operating valve means connected via a pressure outlet or outlets to one or more launchers for launching pigs, wherein each launcher comprises a high pressure connecting means and a launcher tip, which launcher tip has a frustoconical nozzle section for sealingly engaging the end of a tube to be cleaned, said one or more launchers being mounted upon movable location and support means, which means comprises an X-Y frame for maintaining said one or more launchers in position with respect to the ends of said one or more tubes, whereby said one or more tubes may be cleaned sequentially or simultaneously.
