Enhancing Direct Assessment with Remote Inspection through Coatings and Buried Regions |
摘要: |
The objective of the proposed program is to extend electro-magnetic acoustic transducer (EMAT) technology to address two areas of direct assessment and inspection of installed pipelines. One area is the full body inspection of tar coated pipelines for corrosion damage with a minimum of excavation. The other is the measurement of residual stress and plastic strain in pipelines that have been bent or otherwise displaced by movement of the surrounding earth or instability in the soil under pipe supports. Particular emphasis will be placed on non-piggable lines and the use of instrumentation that is suitable for field operation by inspection service providers. This technology was demonstrated after the Prudhoe Bay incident in 2006 where axially oriented electromagnetic acoustic transducer technology was trial tested to detect greater than 30% wall loss from 20 inches away from the pipe support collar. |
