Phased Array Ultrasonic Testing

Phased Array Ultrasonic Testing (PAUT) utilizes multiple shear (transverse) waves fired from a single transducer housing to create an array of angles, which are projected into a color scale image, allowing for a visual representation of indications found within a specimen.

Phased Array device

KEY APPLICATIONS

ASME B31.1/31.3 piping construction projects
Used in conjunction with Time of Flight Diffraction (TOFD) for ASME Sec. VIII Div. 2 pressure vessel construction projects
API Storage Tank construction projects
Pre-turnaround and turnaround in-service inspection

Multi-Skip Phased Array Testing

Multi-Skip Phased Array Testing is a full volumetric screening examination for the detection of both corrosion and pitting with the ability to fire multiple angles and skips, which allows for a full volumetric screening under corrosion deposits, supports, or tank annular rings.

KEY APPLICATIONS

In-service inspection of the critical zone from the tank exterior
Measuring corrosion under the shell to floor weld on a tank from the tank chime
Detecting and measuring corrosion under pipe and tank supports, repads, and blisters
