Abstract
Extensive knowledge is required for proper use of phased array technology with long-range ultrasonic technique (LRUT) and subsequent interpretation of the results in connection with the study of the interaction of low-frequency ultrasonic waves with discontinuities in pipelines. This chapter presents the basic operation principles of the phased array technology, as well as physical processes of spreading of low-frequency ultrasonic waves in pipes. An attempt is performed at summarizing the advantages and shortcomings of pipelines’ control with low-frequency ultrasonic waves, using phased array technology. Advantages, shortcomings, applications, and limitations of the method are present. Sensitivity of the method is analyzed to discontinuity and constituents of the pipeline.
