Title:
PIPE MACHINING APPARATUS FOR LARGE DIAMETER PIPES
Document Type and Number:
WIPO Patent Application WO/2014/022240
Kind Code:
A3
Abstract:
Pipe machining apparatuses, such as traveling pipe cutters, are provided. One such pipe machining apparatus may cut or bevel a hollow vessel (120) while traveling around the vessel, and include a frame (105) including a top end (190) and a bottom end (191) with the bottom end adjacent an outer surface of the vessel. The apparatus also includes a cable (250; 252) wrapped around the vessel and a pair of rollers (240, 260; 242, 262) coupled to the frame with each roller defining a groove therein for receiving the cable. Each roller rotates about an axis that extends generally parallel to a central longitudinal axis of the vessel. The cable is positioned in each groove of the pair of rollers and each axis is positioned between the cable and the outer surface of the vessel. The cable is tensioned to provide a force on the frame in a direction toward the outer surface of the vessel.
