PIPES INSPECTION USING ULTRASONIC GUIDED WAVES

摘要：

Corrosion and pitting defects of pipes are major problems in the oil, chemical, and other industries. These defects probably occur at the outer or inner surface of the pipes and lead to a serious loss of pipe wall thickness. Ultrasonic guided waves testing is introduced as a new non-destructive pipe inspection method for its rapid, long distance inspection and applied to special pipes which are inaccessible to other conventional NDT methods. Ultrasonic guided waves technology can detect the defects such as the wall thinning, wear, corrosion, crack, weld line, and so on. The attenuation variation of guided wave propagating in the pipes is slow, which are suitable to long distance, large range, non-contact, and quick inspection of defects in pipes. The proper wave mode selected can improve the sensitivity of defect inspection in work.
