PART 4: HOW STRESS CONCENTRATION TOMOGRAPHY (SCT) WORKS
SCT™ is based on the science of stress-magnetisation. Whenever there is wall thickness loss in a pipeline wall, there will be an increase in stress. There will also be a change
in the pipeline’s magnetic domains. SCT™ can identify abnormalities in the pipeline’s magnetic field and work backwards from this to infer an exact stress-value at that point in the pipeline. Because any mechanical or metallurgical defect will lead to localised stress zones in the pipeline wall, SCT™ can detect any and all defects that affect buried pipelines.
Please refer to our Whitepaper for further examples of observation scenarios that offer a more in depth explanation of how SCT works. Click Here to View
