ABSTRACT:
A method for testing tubing having the following steps: plastically deforming the tubing with a tubing handling system, the tubing handling system having a reel, a gooseneck and an injector; sensing with at least one sensor acoustic emissions emitted by the tubing during the deforming; and processing acoustic emission signals sensed from the tubing during the deforming. A system for testing a coiled tubing, the system having: a tubing handling system, the tubing handling system having a reel, a gooseneck and an injector; at least one acoustic emission sensor mounted on the tubing handling system and in direct contact with the tubing; and an acoustic emission signal processor in signal transmission communication with the at least one acoustic emission sensor.
