Abstract
An improved punch tool and a method for relocating a section of pipeline using the improved tool are presented. The improvement includes an interior channel running through the center of the shaft of the punch tool and a connector that is attached to one end of the shaft and to a pressure gauge and pressure bleed valve, thereby allowing the operator to use the same tool to cut, gauge, and purge the section of pipeline to be abandoned.

A method for relocating a section of pipeline using a punch tool, the method comprising the steps of:
- attaching a replacement pipeline to a section of original pipeline that is to be abandoned;
- installing a first punch tool at a first location where the replacement and original pipelines intersect;
- installing a second punch tool at a second location where the replacement and original pipelines intersect;
- tapping the original pipeline with the first punch tool;
- purging the pipeline through a pressure bleed valve on the second punch tool;
- tapping the original pipeline with the second punch tool;
- and
- using pressure gauges on the first and second punch tools to determine pressure in the section of original pipeline that is to be abandoned.
