Flaw detector's software simplifies defect sizing
- April 12, 2005
- Product Release
- Testing and Measuring
GE Inspection Technologies' ultrasonic USM 35 flaw detector uses operating software designed to streamline defect sizing in line with API 5UI recommendations for oilfield tubulars.
Using the detector, the operator locates the crack, adjusts the gain to 80 percent amplitude, presses the USM freeze key, and then starts to move the prove to produce an envelope curve. The application software then measures and remembers each amplitude peak and carries out the necessary time of flight calculations for each measurement to provide code-compliant flaw sizing.
Suitable for inspections tasks from flaw detection to corrosion measurement, the detector has two spin and set rotary knobs for setting gain and function values. Direct-access front panel keys are used to select the required dB step width, freeze the displayed A-scan, switch the A-scan to full screen size, and transfer live screen images to an external screen or video projector via a standard VGA output. Instructions are provided in several languages, including most common European languages.
The detector features two independent, color-coded gates with a threshold of 10 percent to 80 percent of screen height that allows two events to be identified and monitored simultaneously. Amplitude for each gate, sound path, or sound path difference can be displayed prominently in the A-scan corner. A high-contrast color display facility also enhances clarity when using angle beam probes in weld inspection. A patented, color-coded leg display allows the signal color to change with sound beam reflection from the workpiece surface. The color display also facilitates highlighting registration curves in DAC and DGS evaluation, filing reference scans, or displaying echo dynamics, because the color can be changed to suit personal preference or ambient light conditions.
High-power lithium ion batteries support the compact detector's portability. They allow at least 10 hours' continuous use and can be recharged while still in the detector. A carrying handle enables positioning the instrument on almost any surface.
