Phased Array Inspection

An array of transducer elements in which the timing of the element’s excitation can be individually controlled to produce certain desired effects, such as steering the beam axis or focusing the beam. For the Inspection of girth welds of Pressure vessels; Corrosion Mapping; Laminations checking; Tube and pipe weld inspections; Inspection of Tee-joints; dissimilar weld inspection and Nozzles Testing.

How ?

The distinguishing feature of the phased array ultrasonic testing is the computer controlled excitation of the individual elements in a multi-elements probe. The excitation of these multiple piezo composite elements generates a focused ultrasonic beam, allowing the dynamic modification of the beam parameters such as angle, focal distance and focal spot size through software.

Applications includes but not limited to:

  • Vessel and pipe work inspection
  • In-service corrosion/erosion monitoring
  • Wall loss measurement through corrosion product
  • Storage tank inspection
