The Wellpro Group Hydraulic Tubing Cutter is a device used to cut production tubing, casing and drill pipe. The tool provides a safe alternative to chemical and explosive cutters. It is typically run in conjunction with Wellpro Groups Hydraulic Tubing Anchor and Positive Displacement Downhole Motor.
Flow through the tool creates the internal pressure required to shift the dual piston and blade cams which force the cutter blades to expand outwards. Jets help to clean the cut area whilst cooling the cutter blades. Upon completion of the cut a pressure drop indication may be witnessed. At this point flow is ceased and a compression spring forces the dual piston back to its starting position.
Pipe cutter blades can be dressed with a variety of cutting structures to suit the particular size and grade of tubular to be cut.
