Methods and devices for extracting an internal pipe/tube element from a connected outer pipe/tube element. Certain embodiments are directed to methods and devices that inwardly distort a pipe/tube at a connection to allow the pipe to be more easily disconnected without damaging the overlapping (outside) half of the connection. Collapsing the pipe adjacent to, and into, the fitting and reducing its circumference allows the pipe to be unscrewed or slide out of the overlapping side of the connection. Embodiments are described including partially cutting thru the male portion of the connection and locally compressing and collapsing the pipe to radially disengage it from interior of the opposing fitting or pipe section. In one method, an interior pipe/tube is disengaged from a fitting or overlapping connection where a connection (weld, adhesive or soldered attachment) is utilized and the connection is selected small/weak enough to be broken in the compression process.
