THE LOGAN INTERNAL PRESSURE PIPE CUTTER UTILIZES PUMP PRESSURE TO ACTUATE THREE CARBIDE-COATED KNIVES TO CUT SINGLE AND MULTIPLE STRINGS OF PIPE FROM 4 INCHES O.D. TO 36-INCHES O.D.
Each different size cutter can be dressed with different lengths of knives to cut different sizes of pipe. Pump pressure is preset by a simple adjustment so the knives will extend at the exact desired diameter. Flow restriction across an orifice feeds a piston that forces the knives out. When the knives reach a preset diameter, the operator will see a sudden pressure drop that indicates that the pipe has been cut.
