METHOD AND SYSTEM FOR DETERMINING PIPELINE DEFECTS |
摘要 |
In accordance with the teachings of the present invention, a method is provided for analyzing RFT data from a data file. The method includes parsing the data file into pipe lengths, calculating a phase profile for the data points within each pipe length, locating potential defects in the pipe length using the phase profiles, determining for each defect a total equivalent phase shift as a combination of a circumferential equivalent phase shift and a non-circumferential equivalent phase shift, and using the total equivalent phase shift to analyze the defect.
