Abstract
A pipe preparation device is disclosed for chamfering pipe ends and placing witness marks thereon to provide a visible indication that the pipes are properly engaged with a coupling. The device includes a body having co-axially aligned receptacles at opposite ends, the receptacles being sized to receive pipes having different diameters from one another. Cutting blades are mounted on the body and project into each receptacle. The blades have cutting edges that engage the end of a pipe inserted into a receptacle and cut a chamfer when the body is rotated relatively to the pipe. Two scoring tools project into each receptacle. The tools have contact surfaces that engage a pipe inserted into the receptacle. The tools in each receptacle are offset from one another and form two circumferential grooves around the pipe when the body and pipe are rotated relatively to each other. The grooves act as witness marks.
