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. 

Masterscan Offers state-of-the-art PAUT services in oil and gas and marine sectors. We provide below PAUT services: 

  • 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.
