Phased Array Ultrasonic Testing

Phased array ultrasonic testing (PAUT) can be used for multitude of tasks. Today in assessment of structures, flaws, fitness for use of the product or equipment and assessment of critical parts require flaw data regarding to location shape and size of the defect. PAUT can provide an accurate assessment of defect and material fracture analysis based on the acceptance standards.

PAUT is used to detect defects that cant be easily detected using conventional volumetric methods such as radiography and manual ultrasonic testing. ANDT specializes in providing PAUT support in petrochemical industries, oil and gas, power, chemical industries. This method also finds applications in pressure vessels and structural welded components providing high standard of quality assurance, when time-restricted inspections are necessary.

A PAUT probe is made up of multiple small ultrasonic probes which can be fired individually. By varying the time of the pulse of each probe ultrasonic rays can be steered into various angles and focal distances. Therefore wave can be swept across the material and thereby covering the object.

Applications for PAUT:

  •    Inspection of forging or casting materials
  •    Weld inspection
  •    Corrosion mapping 
  •    Scanning complex geometry

PAUT can detect:

  •    Weld defects such as lack of fusion, slag inclusions, porosity, cracks, cracks lack of penetration.
  •    Erosion or corrosion.
  •    Inherent discontinuities due to the manufacturing process used.
  •    Environmentally damage.

PAUT has several advantages in comparison to other NDT. Information received can be displayed in a variety of formats like A, B, C scans for reliable and faster inspections. This data can be stored and reviewed later as the need arises. With PAUT shutdown requirement is eliminated hence effect on product is minimal.

ANDT’s PAUT inspectors are highly qualified, holding a minimum of ASNT (American Society of Non-destructive Testing) Level II. Our inspectors are highly qualified to inspect tubes such as condensers, AC tubes, heat exchangers that require special equipment and highly skilled inspectors. ANDT Inspectors are more than capable of running such tasks while the highest level of consumer satisfaction.
