Identifying the Hidden Enemy in Sour Service

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.

"When undetected or misinterpreted, wet H2S damage can cause sudden and catastrophic failure. That's why 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

TALK TO AN EXPERT

Learn From The Experts

Introducing the latest NDT technology in Gecko Robotics’ suite of products: Tri-Lateral Phased Array (TriLat); a revolutionary robotic ultrasonic testing method for the on-stream inspection of pressure vessels in sour service. Join our TriLat Launch Event and hear from Co-Founder and COO, Troy Demmer, as well as the gecko that developed TriLat: Chase David, Director of Operations.

Going live on Wednesday, October 27 at 2:00 PM EDT Troy and Chase will explain the ins and outs of TriLat, what it is, how it works, real-world examples, and how this technology will benefit your facility.

One Unit. Two Sensors. Three Angles.

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.
