ABSTRACT:
A method of and apparatus for cutting substantially vertically disposed pipe is disclosed. The substantially vertically disposed pipe is cut by positioning a receiving member around the pipe at a predetermined distance from the desired cutting plane. A cutting element is mounted on a frame for moving circularly around and radially toward the pipe and the frame includes supports for locating the cutting element at a predetermined distance from the receiving member and for supporting the frame uniformly about the pipe. The frame is positioned around the pipe and the supports are mounted on the receiving member to locate the cutting element within the desired cutting plane. The frame is then prevented from moving relative to the vertically disposed pipe and the cutting element is moved circularly around and radially toward the pipe to cut the pipe along the desired cutting plane at the predetermined distance from the pipe receiving member.
