Tailored to your needs, on time and performed in a professional and safe manner – that’s how DBI, Inc. advanced NDE experts perform their jobs. Technical ability that comes with years of on-the-site experience combined with a drive to meet DBI, Inc.’s goals for quality service, make our advanced NDT team one you can trust. Our company-wide philosophy encourages advanced NDE technicians to be the best in the industry, take their work seriously and understand the importance it has to your operations. Rest assured your NDE technician is qualified, certified (e.g. ASNT, API certified) and able to perform inspections to any code, standard or specification.
Our diverse industry experience allows us to leverage company resources to respond to your NDT needs. DBI, Inc.’s advanced NDE experts perform many types of testing, including:
Phased array applications include:
- Angle beam inspection primarily used for weld inspection
- Time of Flight Diffraction (TOFD) for detection and sizing of defects
- Ability to inspect complex geometries more readily
For weld inspection, phased array increases the probability of detection by offering the inspector additional tools to visualize the reflectors and their position within the weld. The ability to record the weld scans also allows us to utilize phased array for many projects that are constructed to ASME Code requirements.
- A-Scan Presentation: is the amount of received ultrasonic energy as a function of time is displayed. The relative amount of received energy is plotted along the vertical axis and the elapsed time, which may be related to the sound energy travel time within the material, is displayed along the horizontal axis. In an A-scan presentation, it’s possible to estimate relative discontinuity size by comparing the signal amplitude taken from an unknown reflector to that from a known reflector.
- B-Scan Presentation: is a cross-sectional profile view of the test specimen.
- C-Scan Presentation: is a top, plan-type view of the location and size of test specimen features.
In an MFL tool, a magnetic detector is placed between the poles of the magnet to detect the leakage field. Analysts interpret the chart recording of the leakage field to identify damaged areas and to estimate the depth of metal loss.
Digital images can be e-mailed or posted on the web, allowing others to aid in analysis or report results. Viewing software also allows for digital annotation and measurement using a mouse and/or keyboard instead of overlays. CRT uses the same radiation producing devices as conventional radiography. CRT requires no film, which means there is no need to buy or dispose of chemicals.
