Inspection pigs utilize two methods to gather information about the interior condition of the pipeline: magnetic flux leakage (MFL) and ultrasonics (UT). MFL inspects the pipeline by sending ...

Documentation must be maintained to indicate when the source was placed in and removed from storage. The leak test may be performed in the following manner: The Authorized User or RS personnel ...

Infrared thermography can be used as a method of testing for leaks which do not surface. The method is quite expensive and in many cases is undertaken by flying over the areas to be tested. The method ...

But can this still be done in the digital age? It’s something [Windytan] has looked into, as she reconstructs images using leakage from HDMI cables. The tale starts with a mystery RF noise ...

Magnetic field sensors are used to measure magnetic flux and/or the strength and direction of a magnetic field. They are used mainly in scientific measurement, navigation, and industrial applications.

The screws serve to conduct magnetic flux between the magnets, dragging the rotating elements along for the ride. This gearbox appears to be a refinement on [Retsetman]’s earlier design ...

Many of the most popular headphones, even for listeners on a budget, use planar magnetic drivers, and for good reason: the level of detail and clarity they’re able to provide is outstanding.

Take this test to see where you fall on the optimism/pessimism continuum. This test is made up of two types of questions: scenarios and self-assessment. For each scenario, answer according to how ...

Being installed in highly corrosive environments, offshore oil and gas platforms and infrastructure require marine cathodic protection in the form of specialised coatings and preventive maintenance to ...
