Dexon TechnologyMany operators have only seen crack-detection ILI system on a spec sheet. This September, we’re bringing ours to Calgary's International Pipeline Conference & Expo (IPCE).
Weighing in at 1,000+ lbs, 20-in. in diameter, and fully assembled, the UT-CD Hawk was built for transmission lines and is a sight integrity experts won't want to miss.
Beside it will sit an ILI system on the other end of the range: the 3-in. Flexi-ILI, which was engineered to pig the unpiggable—supply lines, gathering systems, back-to-back 1D bends, low flow, and more.
A paper co-authored by Goratouch Ongtrakulkij, Dexon’s innovation lead, will also be presented, laying out hard spot inspection methods that H₂ and CO₂ operators will not want to miss.

Experts from across ILI operations will crew the booth: project managers, the engineer who innovated our latest technologies, and senior leadership.
Looking forward to seeing you there and joining the conversations keeping pipelines sound.
EMSENZ Announcement
Hard spots — particularly features under an inch and narrow hard seams — remain a challenge for current in-line inspection technologies. ExxonMobil's latest paper, co-written by Dexon's Goratouch Ongtrakulkij, presents a novel inspection method purpose-built to overcome that.
Why it matters now: pipelines carrying hydrogen or anthropogenic CO₂ face a different threat profile compared to traditional oil & gas products.
At concentrations up to 1%, hydrogen cuts fracture toughness and accelerates fatigue crack initiation and growth. Hard spots are where that damage concentrates.
Industry standards define a hard spot as longer than 2" in any direction, but failures have been traced to features under 1", and hard seams are narrower still. Current ILI tools lack the resolution to find them, and typically report hardness with a ±50HB sizing error.
The paper presents ExxonMobil's odd-harmonics eddy current technology (EMSENZ), which detects and measures narrow hard spots and seams to within ±30HV.
