With winter approaching, many of you will be performing AUT inspections on high temperature parts in a cold environment. Echo has three types of AUT fluid couplants for your AUT needs. Most liquids increase in viscosity as the…
Ultrasonic inspection of very rough or pitted cast iron or weld surfaces can be challenging. A rough or pitted surface can reduce the energy transmitted into the part, thus reducing the amplitude of the received signal. Additionally, there can be considerable…
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, 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…
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…
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…
Echo Ultrasonics can help you save time by ordering direct. We stock all couplants in all container sizes and offer same day shipping with worldwide delivery.Reduce Cost Echo’s commitment is to provide the highest performance and safety profile ultrasonic…
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….
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 –…
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…
