PIPE CUTTING DEVICE FOR WATER SUPPLY PIPING WORK WITHOUT SUSPENDING WATER SUPPLY

摘要

PURPOSE: To cut a pipe crosswise without generating large cut pieces when the pipe is cut off. ;CONSTITUTION: Prior to a crosswise cutting of a water supply pipe 2, a drain hole 38 is engraved to the pipe 2, and a sealed chamber for pipe cutting work is filled with water. As a result, a heating of an endless diamond wire saw 25 is prevented by the temperature, and the service life of the saw 25 can be extended. And since the water supply pipe 2 is cut by shaving strongly by a diamond, and only chips in metallic powder form are generated, the chips can be disposed easily by a drain, for example.;COPYRIGHT: (C)1994,JPO
