| Abstract | The objective of this project is to build and test an Electro-Magnetic Acoustic Transducer (EMAT) sensor prototype to detect and quantify wall loss and longitudinal cracks in metallic pipes. The sensor will be used to assess small-diameter and unpiggable pipes containing fittings and other restricting features. The initial target pipe diameter is 8 inches, however the commercial goal is to build tools that can navigate in 6- to 12-inch pipes. These sizes are typically used in unpiggable natural gas transmission and distribution systems. Other sizes will be considered based on industry needs. A laboratory assembly (bench-scale unit) has been successfully completed and tested in Phase-1. The work tasks in this proposal build on the results from Phase-1 and include: - Build a prototype of the unit with the data management system and a pull-out mechanism for internal testing of pipe sections with controlled and natural cracks and flaws. - Establish the performance criteria and assess the minimum flaw sizes to be reliably detected by the device. |
