Deep Analysis of In-Line Inspection Data in Oil and Gas Pipelines

The engineering background of in-line inspection (ILI) is introduced. The basic methods and key points of the in-line inspection data analysis of pipeline are introduced in detail from the aspects of defect distribution law, defect development and type evolution, and data compliance analysis. Finally, a typical case is used to demonstrate the analysis of the in-line inspection data of pipeline. Based on the analysis results of the in-line inspection data, corresponding suggestions are proposed.
