ULTRASONIC PHASED ARRAY TESTING (PAUT INSPECTION)

EIWAA Oil and Gas Services provides  Non-Destructive Inspection and NDT Testing Services of  Phased Array Ultrasonic scanning(PAUT Inspection) in Saudi Arabia. Our NDT Inspection Services of PAUT Inspection is used in major oil  Storage tank terminals. A series of ultrasonic testing (UT) probes made up of several microscopic components are used in the advanced non-destructive examination method known as phased array ultrasonic testing or PAUT Inspection Services. Each one of these small components is pulsed individually with computer-calculated timing. More complex geometries that are difficult and slower to inspect with single probes can be examined using this technique. PAUT is typically used for weld inspections and crack detection  for any material where conventional UT techniques have been applied.

PAUT Inspection Services has a number of benefits over other UT Scanning Inspections. In comparison to other types, PAUT Inspection can be performed faster and more accurate. PAUT may generate precise cross-sections of a part by sequentially emitting beams at a variety of various angles.

For detecting weld faults such as lack of fusion, slag inclusion, porosity, inside diameter/outside diameter, cracks, erosion/corrosion, and inherent discontinuities in forged or casting materials, EIWAA Marine Inspection offers weld inspection using the phased array technique and the most advanced instruments.

ADVANTAGES OF PHASED ARRAY ULTRASONIC SCANNING

Phased arrays are more portable, convenient, safe, and fast during inspection than traditional ultrasonic probes. It is simpler to operate, more efficient, and produce fewer false alarms by recording hundreds of signals simultaneously. When combined with simulation, PAUT inspection procedures can be further optimized to enhance problem detection along with significant improvements to data recording and traceability.Phased array ultrasonic testing is radiation-free, offers a permanent record, and has a variety of uses. The lateral position of a defect (depth and height) can also be determined by PAUT since it can identify faults both at the surface and into the volume of a weld (without a dead zone). PAUT Inspection makes it possible to inspect complex structures and provide greater coverage for defect detection. Additionally useful for ultrasonically assessing corrosion or erosion of a test piece, PAUT can also be used to determine material thickness.

 

DISADVANTAGES OF PHASED ARRAY UT SCANNING INSPECTION

Although PAUT is an excellent tool for a variety of applications, it is not the best way to test for metal fatigue, tubing inspections and surface fractures. While PAUT is useful for corrosion detection and the examination of composite materials and thicker welds, eddy current testing is typically preferable in these situations. With several data optimization capabilities and greater sophistication than traditional ultrasonic testing equipment, PAUT equipment should only be utilized by qualified professionals to minimize testing error and maximize PAUT’s advantages.
