Digital Imaging of Pipeline Mechanical Damage and Residual Stress
| 项目名称： | Digital Imaging of Pipeline Mechanical Damage and Residual Stress |
| 摘要： | This project addresses the need for a more reliable means of characterizing pipeline mechanical damage through application of digital eddy current imaging. JENTEK's patented Meandering Winding Magnetometer (MWM) arrays have demonstrated capability to use lift-off measurements to profile the surface of a dented area, while MWM-Array measured magnetic permeability can be correlated with residual stresses around and within the mechanical damage site. Successful completion of this program will result in enhanced remaining life prediction capability for pipelines suffering mechanical damage and a reliable decision support tool for pipeline owners and operators. This will enable operators to avoid overly conservative decisions while enhancing pipeline safety. |
