ABSTRACT:
A method and apparatus of sealing and cutting an underground pipeline, such as a gas line or the like, at or near a point where it connects to a main utilizes an expandable plug which may be inserted in the line without the need to excavate to obtain access to the point of sealing. A thermally stabilized cross-linked preshrunk polyolefin plug is inserted into the line on a heater element. The plug may be inserted from a point where the line exits the earth. Once the plug is inserted on the end of the heater element, the heater element is heated causing the plug to expand fitting it tightly inside of the line at or near the main. The heater element may then be withdrawn, and the line may be cut adjacent the inserted plug.
