IN-SITU CONDUIT CLEANING PROCESS

摘要

IMPROVED IN-SITU CONDUIT CLEANING PROCESS The in-situ cleaning of conduits is enhanced by the passage therethrough of a propelling gas stream having entrained therein cleaning particles of a regular, non-random configuration, and having less than spherical symmetry. The aerodynamic orientation of the particles in the gas stream is such that surprising and unexpectedly improved cleaning action is obtained thereby, particularly in the cleaning of conduits having difficult-to-remove deposits thereon.
