Scott Cargill, Past President of ASNT shared the below auto-ignition story with us. It is well worth the read. Auto-Ignition? What’s that? Wait a minute, I’m almost positive it has something to do with the MSDS – Materials Safety Data Sheet (old school) or with the harmonized global system of today just SDS – Safety […]

Selecting the Correct High Temperature UT Couplant
When performing UT inspections at elevated temperatures, it is critical to select the correct couplant, both for performance and safety. Thickness gauging and corrosion mapping are often conducted at temperatures between 500°and 1000°F (260° and 538°C) where auto-ignition may occur. Ultrasonic transducers and instruments capable of operating at temperatures up to 950°F (510°C) are routinely […]
Solving issues with wedge and part coupling failure in phased array inspections
During phased array testing, element dropout can be a problem. Common causes include dead elements in the transducer or a failure of the wedge-to-transducer or wedge-to-inspection-part coupling. Let’s look at each of these coupling failures in detail before offering some solutions for each of these PA testing issues. Wedge-to-transducer coupling failure is often partial and […]
VersaSonic is a leading high temperature couplant, but … read how Caterpillar and power generation equipment manufacturers are using it.
VersaSonic, the most versatile ultrasonic testing couplant available, will now be used in even more environments after recent developments. Caterpillar Inc., the well-known equipment and engine manufacturer, has approved VersaSonic for use on its CAT equipment. Caterpillar is distributing VersaSonic through its dealers worldwide for UT thickness gauge inspections in harsh environments, from sub-zero to […]
New Fluids for NDT can eliminate fire, smoke and residue
Echo Ultrasonics has recently become the exclusive distributor of SpectrumGlide AUT-NDT Fluid Couplant in the U.S. and Canada. SpectrumGlide, developed by Eclipse Scientific, has a viscosity formulated to reduce runoff and provide longer dwell time at temperatures from -50° F to 730° F (-45° C to 387° C). The addition of SpectrumGlide gives Echo Ultrasonics […]
Looking for the right fluid for your AUT Inspections?
Echo’s automated ultrasonic testing fluids offer solutions for those who’ve encountered problems with other fluids. Often, fluids are too thick to pump, run off too fast, smoke too much, auto-ignite, freeze or vaporize so quickly that there’s no time to conduct the inspection. With AUT fluids in multiple viscosities (thicknesses) spanning a broad range of […]
Why VersaSonic™ outperforms Sono 600®
Vaporization of VersaSonic™ vs Sono 600® The above plot is a technical representation of why VersaSonic (top line) outperforms Sono 600 (bottom line). The plot depicts the weight loss of each couplant due to vaporization over time at 200°C (392°F). Sono 600 loses significantly more mass and vaporizes faster than VersaSonic. Vaporization produces gas […]
New UT Fluid Couplant Grades
We’ve expanded our line of Echo 8HT fluid UT couplant to include three additional viscosities. Performance of a broad range of AUT and MUT ultrasonic flaw and thickness gaging applications from -50°F to 800°F (-45°C to 425°C) is possible with these four grades, with minimal residue and great signal to noise ratio. Grade 1 is the lowest viscosity fluid (100 […]
Introducing HiTempco™ UT Couplant
Introduced in the mid 1970’s by Aerotech / Krautkramer Branson and sold by GE Inspection Technologies for decades, HiTempco has been the standard of performance in silicone based ultrasonic couplants. With a broad temperature range of -50°F to 775°F (-45°C to 412°C), its applications range from high temperature thickness gauging and flaw detection to ambient […]

VersaSonic Ultrasonic Couplant
You may be aware that VersaSonic® has superior performance from -10 to 750°F, however, did you know: VersaSonic is available in medium viscosity for optimal spread-ability and high viscosity to “stay in place” on a transducer, pipe or overhead surface. VersaSonic is available in open-top 1 and 5-gallon pails (5-gallon dispensing pump included at no […]
