A pipe cleaning tool for cleaning pipe surfaces is configured for operative engagement with a drill motor. The cleaning tool includes a body having a sidewall extending between a first end and a second end of the body. Cleaning blades located in each of a plurality of slots which extend to respective openings in the sidewall of the body. The cleaning blades are biased to project past the sidewall and thereby contact a pipe surface positioned adjacent the sidewall to clean the pipe surface of oxidation and dirt when the body of the cleaning tool is rotated by the engaged drill motor.

The invention proposes a system and a method for the selective extraction of viscous hydrocarbons from tanks and other containers. The system comprises the following components for heating the hydrocarbons: a steam ejector -3-, in which there takes place an eddy diffusion of its drive steam with the gases it aspirates by means of the Venturi effect, and a perimetric heating conduit -5- externally attached to the tank or container. The method comprises the following operations: heating a surface layer of hydrocarbons by means of the gases injected by the steam ejector, causing a selective flow of hot hydrocarbons to the perimetric conduit; localized heating of the hydrocarbons with the perimetric conduit, causing the precipitation of water and a selective flow of the hottest hydrocarbons to an extraction pump; and extracting the precipitated water and the hydrocarbons flowing selectively from the perimetric conduit by means of two pumps.
