Gauge/Paraffin Cutters 

The gauge cutter is also called as tubing scrapper. The scrapper is used for clearing away the attachments on the wall of the tubing before the underground operation is started, so that the inner diameter of the tubing is smooth and can meet the downhole operating requirements of other tools, and the outer diameter is at least 2mm greater than the instrument string or the operating tool string. It needs to put the tube scrapper before the steel wire operating tool goes down, therefore, it can determine whether the tool string can pass through the tubing and determine the position of the joint in the tubing.

    Note: Tubing Gauge / Paraffin Cutter are available in MM increments within the specified O.D. ranges.
