Tri-Lateral Phased Array (TriLat) is a revolutionary robotic ultrasonic testing method for the on-stream inspection of fixed equipment in caustic service.
TriLat identifies environmental cracking, including Hydrogen Induced Cracking (HIC), Stress Oriented HIC (SOHIC), and Sulfide Stress Cracking (SSC), and HTHA in carbon and low alloy steel equipment at unprecedented productivity and resolution.
Covers 2.4 linear ft/min (0.7 m/min), up to 10x faster than conventional AUT depending on probe size.
Over 150K UT readings per ft2 (1.6M readings/m2) are visualized through detailed A, B, C, and D scans.
Positively identify laminations, inclusions, blisters, periphery cracking, and stepwise cracking.
Passive and active focalization combine to identify damage at a depth of 4 inches (102 mm).
Inspect in-service assets up to 240 degrees Fahrenheit (116 Celsius).
Inspection, data analysis, and damage identification are performed by ASNT Level III certified technicians.
Tri-Lateral Phased Array is an ultrasonic testing technique unlike any other with the ability to identify and quantify cracking, blistering, and laminations as small as one millimeter. Watch Chase David, Director of Operations and Tri-Lateral Co-Creator, explain the genesis of the technique, its unique characteristics and capabilities, and case studies.
