The EMAT arrangement enables a single receiving EMAT to monitor both the test signal and the returning reflection from the pipewall defect thus providing each signal with its own internal reference. The number of transducers and their positional relationship limits the generation of interference signals, is conservative in power consumption, and provides a tool having enhanced negotiability through the pipeline."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"In-line inspection tool for pipeline integrity testing","description":"Apparatus and methods are provided for non-destructive in-line pipeline inspection utilizing electromagnetic acoustic transducer (EMAT) technology wherein the EMATs are arrayed circumferentially in a ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8479577","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
