- Tiny Robots Find Defects in Plastic Pipelines Without Disrupting Service. // American Gas;Oct2006, Vol. 88 Issue 8, p35
The article reports on the new technology that is being developed by the Department of Energy's National Energy Technology Laboratory (NETL) to detect flaws in plastic natural gas pipelines in the U.S. The new technology is a tiny robot that carries a microcomputer-controlled sensor to identify...
- Detection of discontinuities of a metal and a protective coating on pipelines. Popov, V. A.; Matvienko, A. F. // Russian Journal of Nondestructive Testing;Jul2009, Vol. 45 Issue 7, p449
A technique of diagnostic nondestructive testing is proposed that ensures reliable detection of flaws in the interface of the protective coating on pipelines based on discrimination between discontinuities in the coating and the tube metal.
- Flaw Depth Sizing Using Guided Waves. Cobb, Adam C.; Fisher, Jay L. // AIP Conference Proceedings;2016, Vol. 1706 Issue 1, p1
Guided wave inspection technology is most often applied as a survey tool for pipeline inspection, where relatively low frequency ultrasonic waves, compared to those used in conventional ultrasonic nondestructive evaluation (NDE) methods, propagate along the structure; discontinuities cause a...
- Comment. Gardner, W E // Insight: Non-Destructive Testing & Condition Monitoring;Jul2013, Vol. 55 Issue 7, p346
An introduction to the journal is presented in which the editor discusses various reports published within the issue, including one on the problem of flaw detection in aluminum castings, another on a hybrid model for leak detection in gas pipelines, and the use of visual-based techniques in the...
- Crack squad. Moll, N. // Flying;May90, Vol. 117 Issue 5, p58
Discusses how technicians at Physical Acoustics in Princeton, New Jersey have devised a way of interpreting the language spoken by cracks and corrosions in aircraft, allowing them to find hidden structural flaws.
- Case studies in the application of advanced technology to pipeline flaw assessment. Anderson, Ted L.; Smith, Ian // Journal of Pipeline Engineering;Jun2014, Vol. 13 Issue 2, p103
PIPELINE OPERATORS HAVE been quick to adopt technological advances in a number of areas, including in-line inspection (ILI). However, when it comes to evaluating flaws and other damage detected by ILI and other means, much of the pipeline industry still relies on simplified assessment...
