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.

13. A method of testing tubing comprising:
-
providing a tubing handling system comprising a reel, a gooseneck, and an injector; sensing, with at least one rolling sensor in direct contact with the tubing, acoustic emission signals emitted by the tubing while being plastically deformed by the tubing handling system; processing the sensed acoustic emission signals, wherein the processing comprises amplifying, filtering, and analyzing with knowledge-based software, the sensed acoustic emission signals; and generating an alarm when the processed acoustic emission signals indicates that a region of the tubing contains a defect having insufficient strength to support a stress level of at least about 60% of the tensile strength of the tubing.
