Phased Array Services

Phased Array Ultrasonics (PAUT) is an advanced ultrasonic technique that permits the shaping and steering of the ultrasonic beam angles, dynamic depth focusing and enhanced beam coverages. The Phased Array beam analyzes through the object which results in a recordable image that reveals defects hidden inside a structure or weld. The technology is much like an ultrasound our sonogram used in a hospitals or deep-sea diving.

Why Use Phased Array?

Phased Array offers superior imaging techniques and a high level of reproducible results that minimizes human error compared to other ultrasonics. 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:

Inspections

  • New construction; rigorous ASME, API, AWS, and other UT in lieu of RT inspections

    • Pressure boundary welds; i.e. girth, long seam, 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; Greylock, 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

PAUT angle beam inspection delivers uniform sensitivity across the entire beam (angle sweep and range) making it well suited for automation, flaw detection, and code based accept / reject decisions.

PAUT straight beam corrosion mapping quickly captures internal metal loss and lamination data that can correlated to ILI reports and analyzed to customer specifications.
