Abstract

A unique capability has been developed in the application of guided wave (GW) ultrasonic techniques for nondestructive evaluation (NDE) of insulated pipe. Many guided wave modes are established in pipe walls when excited by ultrasonic waves. Some of these modes leak energy into the liquid filling the pipe or into the insulation covering the pipe, while others stay largely in the pipe wall and interact with flaws, including corrosion-induced defects. The success of the guided wave method as a viable NDE method for this application is critically dependent upon the ability to preferentially select the modes most sensitive to defects and exploit them for the information they carry about the existence, location, and geometry of corrosion-induced flaws. The feasibility of the guided wave approach for inspection of insulated pipe has been successfully demonstrated, and current work is aimed toward developing methods and systems capable of field inspection.
