Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT)

Phased Array Ultrasonic Testing (PAUT) is an advanced method of ultrasonic testing.

When applied to steel the phased array image shows a slice that may reveal defects hidden inside a structure or weld. 

PAUT Applications and Benefits:
 

  • Butt welds inspection in pipes and pressure vessels and large structures, Bifurcation lines, Valve bodies, etc
     

  • Corrosion mapping to estimate thickness at finite points in pressure vessels, pipes, tanks and structures. 
     

  • PAUT scans on complex geometries including painted cylindrical, trapezoidal fuel transport tankers
     

  • Individually tailor development of qualification blocks, configuring rigs for data collection and levels of post-analysis reporting
     

  • High pressure and high temperature piping welds at power station sites using encoded scanning on circumferential and seam welds between various wall thickness
     

  • Inspection of complex geometry branch welds with variable weld profile using encoded scanning for accurate sizing of internal defects
     

  • Turbine and generator components inspections with special focus on areas of high stress concentration turbine blade roots and geometry changes along exciter cooling fans
     

  • In-site inspection of transverse cracks in shafts, axles, spindles, holds down bolts.
     

  • Precise detection, measurement and reporting of smaller cracks for condition monitoring or repair.
