Abstract:
1. A method of cleaning out pipe systems, comprising the steps of: generating pressurized gas to form a moving air stream into one end of a piping system having pipes with piping diameters selected from the group consisting of approximately ½ inch, approximately ¼ of an inch, approximately 1 inch, approximately 1½ inch and approximately 1¾ inches; intermittently injecting bursts of abrasive particles in separate burst shots into the moving air stream at the one end of the piping system, and the abrasive particulates per shot having different range values for each of the piping diameters; cleaning interior wall surfaces of the pipes with the separate burst shots of the abrasive particles; reducing at least one of burrs or interior lips in the interior wall surfaces of the pipes, with the separate burst shots of the abrasive particles that have been intermittently injected into the moving air stream at the one end of the piping system; and removing abrasive particles and debris caused by each one of the separate burst shots of the abrasive particles.
