The Phased Array Technique of Ultrasonic Testing is a process wherein UT data are generated by controlled incremental variation of the ultrasonic beam angle in the azimuthal or lateral direction while scanning the object under examination. This process offers an advantage over processes using conventional search units with fixed beam angles because it acquires considerably more information about thereflecting object by using more aspect angles in direct impingement. Each phased array search unit consists of a series of individually wired transducer elements on a wedge that are activated separately using a pre-selectable time delay pattern.Flaw sizing is normally performed by measuring the vertical extent (in the case of cracks) or the cross-sectional distance (in the case of volumetric/planar flaws) at the 6 dB levels once the flaw has been isolated and the imagenormalized. Tandem sizing and analysis uses techniques similar to pulse-echo but provides images that are easier to interpret since specular reflection is used for defects oriented perpendicular to the surface. For cracks and planardefects, the result should be verified using crack-tip-diffraction signals from the upper and lower ends of the flaw, since the phased array approach with tomographic reconstruction is most sensitive to flaw tip indications and isable to give a clear reconstruction image of these refraction phenomena.

Oxide Scale Measurement is generally used for detetion of deposition of oxides on the inside of the tubes used in power plants.
A significant limiting factor that affects tube life in fossil fired steam boilers is the growth of iron oxide scale (magnetite) on the inside and outside tube surfaces. The oxide scale, which forms under long term exposure to very high temperatures, acts as a thermal insulator. While external scale limits heat transmission into the tube and reduces boiler efficiency, internal scale buildup represents a potentially more serious problem. The insulating effect of internal scale limits heat transmission into the water vapor inside the tube, which in turn causes chronic overheating of the tube wall and promotes accelerated metallurgical failure. Non Destructive measurement of internal oxide scale thickness is of major interest in the power generation industry and other users of fossil fuel steam boilers, since scale thickness may be used to predict remaining tube life.
