Large volumes of energy products are transported via pipeline over long distances between production, processing, and consumption sites. The most common pipeline inspection method, magnetic flux leakage (MFL), uses high magnetic fields to detect corrosion. However, to detect mechanical damage, the magnetic field must be at lower levels. While commercial MFL tools can be readily changed to a single low field configuration, signal processing and interpretation of the data from these ...

Tools To Detect Mechanical Damage In Pipe.(GTI and Department of Transportation sign agreement to advance pipeline inspection technology and tools)
Pipeline & Gas Journal ; While today's in-line inspection devices can effectively locate corrosion and metal loss, they are limited in their ability to detect one of the most significant precursors to pipeline failure--mechanical damage to the outer pipe surface. In response, GTI and the U.S. Department of Transportation
Mechanical damage detection with high-resolution MFL technology.(Inline Inspection)(Magnetic Flux Leakage )
Pipeline & Gas Journal ; Due to recent well-publicized pipeline failures and the resulting regulatory focus on pipeline integrity and safety, much more attention is now focused on the subject of mechanical damage in pipelines. The development of inline inspection (ILI) tools capable of detecting the presence of mechanical
Is Earth's faltering magnetic field turning south?
Deseret News (Salt Lake City) ; SAN FRANCISCO -- In the recent movie "The Core," Earth's molten core stops spinning, with dire effects on the magnetic field that protects the planet from energy-charged particles from the sun. People with pacemakers fall dead in the street; the Golden Gate Bridge collapses. Scientists have known
Advancing ILI technology assesses mechanical damage.(Smart Pigging)(in-line inspection)
Pipeline & Gas Journal ; Mechanical damage is becoming more highly defined today as a threat to pipeline integrity. For the purpose of this discussion, mechanical damage is defined as combinations of dents, gouges, and/or cold work caused by the application of external forces. According to the Office of Pipeline Safety,
