Using Advanced Inspection Method (Three-Dimensional Ultrasonic) in Recognition of Defects in High Thickness Pipelines

Abstract

In this study, using Harfang Code 32 device, the slag catcher pipelines in one of the South Pars phases were tested. In radiography method of these lines, no clear defect was observed in radiographic films due to the high thickness of 40 mm. However, marvelous results were obtained using advanced ultrasonic. Review and analysis of the results will result in high potential of three-dimensional ultrasonic method in identifying defects in pipelines with high thicknesses and preventing financial and life-threatening risks during the use of these refineries in the future.
