Tubing cleaning and cutting method

Abstract

Methods of cutting pipe and removing contaminants from surfaces of pipe ( 40 ) and fittings ( 37, 38, and 39 ) that connect pipe ( 40 ) by soldering. During the cleaning and cutting of the pipe ( 40 ), contaminants are removed by way of a pipe cleaning abrasive ( 24 ) that is connected to the cleaning and cutting device. Rotating the device around the axis of the pipe ( 40 ) cleans and cuts the pipe until severed. Fittings ( 37, 38, and 39 ) are cleaned by a streamlined fittings cleaning abrasives ( 31, 32 and 33 ) located on the cleaning and cutting device. A fitting ( 37, 38, or 39 ) is placed over the fittings cleaning abrasives ( 31 or 32 and 33 ) and pushed so that the fittings cleaning abrasive ( 31,32 or 33 ) enters the fitting of the proper diameter ( 37, 38, or 39 ) removing the contaminants. The pipe cleaning abrasive ( 24 ) and the fittings cleaning abrasives ( 31, 32, and 33 ) may be replaceable. The cleaned surfaces of pipe ( 24 ) and fittings ( 37, 38, and 39 ) are ready to continue soldering process.
