Phased Array Ultrasonic Testingn(PAUT)
Why Phased Array
Phased Array offers definitive advantages over conventional ultrasonics by providing imaging that can often produce more accurate results, and like most imaging techniques, provides a higher level of reproducible results while minimizing human error. Phased Array also allows for enhanced coverage of a given component or weld from fixed and multiple positions including achieving beam coverage on complex geometries where conventional ultrasonic techniques were inadequate. Some of the many applications for Phased Array are as follows:
Advantages of using Acuren Phased Array:
Faster process than manual ultrasonic testing
Higher reliability
Enhanced quality and accuracy
Increased probability of detection
No radiation exclusion zone
Ability to test welds with multiple angles using a single probe
Data can be captured, stored and referenced at a later date
Proven, qualified procedures
Weld inspections
New construction; rigorous ASME, API, AWS and other UT in lieu of RT inspections
Pressure boundary welds; i.e. girth, longseam and nozzles
Non-pressure boundary welds; i.e. attachment welds, tray welds, gussets, etc.
In service rigorous on-stream inspection program including high temperature up to 700F
Pressure vessels, reactors and piping
Pipeline integrity
Critical flaw sizing and monitoring
Some additional applications may include:
Flanges; graylock, raised face, ring groove, etc. for cracking or corrosion
Bolts, shafts, pins
Tube to header welds
Turbine blades
Most any other component with an area for access to provide Phased Array
Cost and Quality Benefits of Phased Array
Phased Array delivers significant benefits that improve operational efficiency and potential cost savings:
The most revealing advantage is in the area of “UT in lieu of RT” and the elimination of radioactive sources and the barricading or exclusion zones, including the ability to perform PAUT examinations with minimal impact to construction crews or other work activities.
Enhanced weld quality when required and enhanced productivity with less crewmembers.
Enhanced sensitivity for the more critical flaws (non-fusion, cracking) and less sensitivity for the less critical flaws (slag, porosity).
When combined with Time of Flight Diffraction (TOFD) and our fully automated systems/process, it is not uncommon to achieve 300 – 500 linear feet of weld inspected in one shift with a single crew; ideal for tanks and large vessels.
