  2. Ultrasonic thickness measurement - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_Thickness...

    An ultrasonic thickness gauge is a measuring instrument for the non-destructive investigation of a material's thickness using ultrasonic waves. The usage of an ultrasonic thickness gauge for non-destructive testing to check material properties such as thickness measurement, is regular in all areas of industrial measurements.

  3. Internal rotary inspection system - Wikipedia

    en.wikipedia.org/wiki/Internal_rotary_inspection...

    Internal rotary inspection system (IRIS) is an ultrasonic method for the nondestructive testing of pipes and tubes. The IRIS probe is inserted into a tube that is flooded with water, and the probe is pulled out slowly as the data is displayed and recorded. The ultrasonic beam allows detection of metal loss from the inside and outside of the ...

  4. Corrosion mapping by ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Corrosion_mapping_by_ultra...

    Corrosion mapping by ultrasonics is a nonintrusive (noninvasive) technique which maps material thickness using ultrasonic techniques. Variations in material thickness due to corrosion can be identified and graphically portrayed as an image. The technique is widely used in the oil and gas industries for the in-service detection and ...

  5. Ultrasonic testing - Wikipedia

    en.wikipedia.org/wiki/Ultrasonic_testing

    Ultrasonic testing is often performed on steel and other metals and alloys, though it can also be used on concrete, wood and composites, albeit with less resolution. It is used in many industries including steel and aluminium construction, metallurgy, manufacturing, aerospace , automotive and other transportation sectors.

  6. Intrinsic safety - Wikipedia

    en.wikipedia.org/wiki/Intrinsic_safety

    Intrinsically safe mobile phones must meet special battery design criteria in order to achieve UL, ATEX directive, or IECEx certification for use in explosive atmospheres. Only properly designed battery-operated, self-contained devices can be intrinsically safe by themselves. Other field devices and wiring are intrinsically safe only when ...

  7. Terahertz nondestructive evaluation - Wikipedia

    en.wikipedia.org/wiki/Terahertz_nondestructive...

    There are millions of dollars of ultrasonic equipment in the field and on the market that are used as thickness gauges and density meters. When terahertz nondestructive evaluation is fully commercialized into a more portable form, and becomes less expensive it will be able to replace the ultrasonic instruments for structural plastic , ceramic ...

  8. Robotic non-destructive testing - Wikipedia

    en.wikipedia.org/wiki/Robotic_Non-Destructive...

    Robotic non-destructive testing (NDT) is a method of inspection used to assess the structural integrity of petroleum, natural gas, and water installations. Crawler-based robotic tools are commonly used for in-line inspection (ILI) applications in pipelines that cannot be inspected using traditional intelligent pigging tools (or unpiggable pipelines).

  9. Laser ultrasonics - Wikipedia

    en.wikipedia.org/wiki/Laser_ultrasonics

    Laser-ultrasonics uses lasers to generate and detect ultrasonic waves. [1] It is a non-contact technique used to measure materials thickness, detect flaws and carry out materials characterization. The basic components of a laser-ultrasonic system are a generation laser, a detection laser and a detector.
