A Great Couplant Just Got Even Better
EchoTherm ExtremeTM – the only no-residue, high-temperature ultrasonic couplant for use above 805°F (429°C) has been reformulated to increase transmission performance up to 1250°F (675°C). EchoTherm Extreme facilitates high temperature inspections…
Scott Cargill Shares His Experience with Auto-Ignition During a UT Inspection
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…
Important Considerations for Couplant Selection
Couplant selection is a critical factor to insure reliable, repeatable UT inspection results and to optimize productivity. Couplant is required due to the acoustic impedance mismatch between air in the interface with the transducer and the test…
API Subcommittee on Inspection and Mechanical Integrity to Address the Auto-Ignition of NDT Ultrasound Couplants
As recently Published in Inspectioneering Journal: “The API Committee on Refinery Equipment (CRE) made a recommendation that SCIMI address the auto-ignition of NDT ultrasound couplants by including new paragraphs in the upcoming rewrites of API RP 572 (Inspection…

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…
AUT Fluids: It’s All About the Vaporization Rate
Determining the best AUT fluid for an application involves several factors: Maximum temperature of test object (or under insulation) Viscosity must be within the capability of the pump:This decision includes knowing the viscosity at the minimum…
Silver Bullet Couplants – for Inspections That Are Almost Impossible without the Right Couplant
Many UT applications require a specialty UT couplant. For difficult inspections that require high acoustic impedance, shear wave, reduced surface noise, extreme temperature range or extended service life for sensors, we have the right couplant….
