Patent ID: 7414395

Claim:
A method for detecting stress corrosion cracking (SCC) of pipelines, comprising: identifying pipeline locations and pipeline conditions that are amenable to inspection by a magnetic flux tool; performing two inspections on the pipeline, one inspection is performed to collect the magnetic flux inline (MFL) data and a separate inspection is performed to collect transverse magnetization flux lines (TFI) data, wherein the MFL data and TFI data are distinct; after collection of the TFI data and the MFL data, aligning separate signals descriptive of pipeline features generated from each of the MFL data and the TFI data, wherein the alignment includes presenting the separate signals simultaneously to show the same pipeline feature; evaluating a number of pipeline features indicated by the aligned separate signals from the MFL data and TFI data, the features including potential crack field features and potential corrosion features, and based upon results of the evaluation identifying potential crack fields for physical inspection.
