Tri-Lateral Phased Array (TriLat) is a revolutionary robotic ultrasonic testing method for the on-stream inspection of fixed equipment in sour service.
TriLat identifies wet H2S damage mechanisms, including Hydrogen Induced Cracking (HIC), Stress Oriented HIC (SOHIC), and Sulfide Stress Cracking (SSC) 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.
"When undetected or misinterpreted, wet H2S damage can cause sudden and catastrophic failure. TriLat was developed with multidirectional focalization customization and two-axis resolution to efficiently and accurately confirm wet H2S damage."
- Jose Aparicio, NDT Technology Manager & Co-Creator of Tri-Lateral
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.
TriLat combines the power of two probes containing three total angle beam sets in one unit for unparalleled resolution to identify wet H2S damage at the earliest stages. One probe is set in a lateral configuration and the other is in a linear configuration. They are set at different skew angles and contain 64 element transducers each. The result is 128 elements firing with an electronic resolution of 0.024”x0.039”, which provides a data density that is 25x greater than conventional AUT.
Inspections with Tri-Lateral Phased Array are available immediately.
