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.
