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 that were previously impossible. Look for the lavender top on the EchoTherm Extreme tube as your assurance of the best performing high temperature UT […]

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 Data Sheet (old school) or with the harmonized global system of today just SDS – 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 object. If there were no couplant, nearly all of the energy from the transducer would be reflected back […]
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 of Pressure Vessels) and API RP 574 (Inspection Practices for Piping System Components). These paragraphs will incorporate […]

SuperSoniX™ – A new UT Couplant with a Historic Name
In May of 1940, Floyd Firestone, a Professor in the department of Physics at the University of Michigan, filed US patent 2280226 in which he described an instrument for the detection of flaws and measuring thickness in metal objects. Dr. Firestone used the term “Supersonic Vibration Waves” to describe what we now refer to as […]
VersaSonic® – A better alternative to Sono® 600
VersaSonic is the most versatile couplant with UT applications including: High temperature inspections – up to 700°F / 371°C Extreme weather conditions – rain, snow, mud and sleet Freezing temperatures down to -10°F / -23°C Power generation equipment – insulation compatible Best corrosion inhibition of all couplants VersaSonic is available in two viscosities to optimize […]
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 […]
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 temperature of the fluid reservoir and supply lines and the maximum length of the line from pump to […]
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. High Impedance Couplant: A high impedance couplant typically has an acoustic impedance above 3.5 M Rayls. Water based couplants typically have […]
