چکیده
Detection of Metal Defects on Gas Distribution Pipeline by Remote Field Eddy Current (RFEC) Using Finite-Element Analysis — It is necessary to find out whether there are metal defects on underground gas distribution pipelines without excavation in order to establish safety strategies for replacement or maintenance. The metal defects are classified into general corrosion, stress corrosion cracking, lamination, pits, and metal loss, which cause leak or partial damages to a gas pipeline. Therefore, it is required to develop an effective method in the form of an in-line inspection concept that could be implemented internally into a gas pipeline. Oil & Gas Science and Technology – Rev.

Defect Detection and Segmentation Framework for Remote Field Eddy Current Sensor Data
Remote-Field Eddy-Current (RFEC) technology is often used as a Non-Destructive Evaluation (NDE) method to prevent water pipe failures. By analyzing the RFEC data, it is possible to quantify the corrosion present in pipes. Quantifying the corrosion involves detecting defects and extracting their depth and shape. For large sections of pipelines, this can be extremely time-consuming if performed m...

متن کاملNumerical Analysis of the Effect of Sinusoidal Pressure Path on Thinning of Tube in Hot Metal Free Bulging Process
Light-weight and high strength alloys such as Al-Mg alloys are used in order to reduce the weight of industrial components. However these materials should be formed at elevated temperatures due to their poor formability at room temperature. Hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. Recent investigation on tube hydroforming showed positiv...
