AUT Fluids

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 very hot conditions. VersaSonic is being distributed as Caterpillar part number 545-8721.

Power generation equipment manufacturers have approved VersaSonic for its compatibility with electrical wiring insulation for use in their power generation rotor inspections. VersaSonic does not contain water, is non-corrosive and is low in toxicity.

Acuren, Team Industrial Services, Mistras, IRIS NDT and many other inspection companies select VersaSonic for its high temperature properties and two viscosities:

  • high-viscosity VersaSonic for hot piping over 350° F (177° C) and for direct placement on the transducer, and
  • medium-viscosity VersaSonic for spreading on parts and at temperatures under 350° F and as low as -10° F.

The nondestructive testing industry chooses VersaSonic for its technical performance. VersaSonic has a lower rate of vaporization and evaporation above 350° F than competitive couplants, resulting in longer inspection windows and less need for reapplication of the couplant. Tests of weight loss from evaporation over time have shown that VersaSonic loses less than 1 percent of its original weight by the time the product has reached 392° F, while competing products can lose twice that amount.

VersaSonic is plant-based and biodegradable. It does not contain peanut oils, tree nut oils or silicones. Additionally, VersaSonic provides excellent corrosion inhibition for steel and cast iron and it can be left in place providing it won’t interfere with subsequent operations such as painting or electroplating. VersaSonic can be removed with a wipe from a rag or cloth; for complete removal, dish detergent and water or Echo 4HT can be used.

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 a full range of automated ultrasonic testing fluids, with viscosities ranging from 125 to 5000 cps and covering temperatures from -70° F to 1200° F (-57° C to 649° C).

SpectrumGlide’s formulation results in faster and more efficient testing by allowing it to remain on pipes, tanks and other surfaces longer without draining off. Because it can be used in testing environments up to 780°F (415°C), it’s a versatile fluid for high-temperature AUT applications.

To learn more about SpectrumGlide, or to give it a trial in your testing, contact us. Free samples are available for evaluation; just fill out this short form online.

AUT uses automatic equipment to run a variety of inspections in numerous industries, from corrosion mapping to thickness gauging to weld inspection. For example, AUT is an efficient and accurate method for analyzing the integrity of pipeline welds in the oil and gas industry.

50 years of developing and manufacturing the world’s leading NDT ultrasonic couplants enable Echo Ultrasonics to provide customers with the most cost-effective, highest-performance and safest couplants for each application. Let us recommend and provide samples of the right couplant with today’s technology for your specific needs.

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 temperatures, Echo has solutions to each of these problems. Several Echo AUT fluids are water-soluble, too, so they don’t leave a film on water when used at sea.

Echo AUT fluids have viscosities ranging from 125 to 5000 cps and covering temperatures from  -70° F to 1250° F (-57° C to 675° C).

The five AUT fluids listed below are arranged by increasing Operating Range:

Echo 4HT is a water-soluble fluid with an operating range of -70° F to 450° F (-56° C to 230° C). It has low toxicity and good surface wetting. Echo 4HT is slow drying and is compatible with a broad range of materials, including most metals, plastics and composites.

VersaSonic fluid is a plant-based, biodegradable fluid with low toxicity and an operating range of -10° F to 700° F (-23° C to 371° C). Above 400° F (200° C), VersaSonic works best when sprayed or pumped (discharged) at the point of use.

Echo 8HT  features minimal residue in a broad range of AUT and MUT ultrasonic flaw- and thickness-gaging applications, from -50° F to 800° F (-45° C to 425° C). The Echo 8HT line is compatible with all metals and most plastics. Echo 8 HT is available in three viscosities: grades 1, 4 and 10.

SpectrumGlide, a high-performance fluid for high-temperature testing, 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). SpectrumGlide was developed by Eclipse Scientific and is distributed under license by Echo.

EchoTherm Extreme fluid is the highest-temperature fluid couplant available. EchoTherm Extreme is a high-viscosity fluid that produces less smoke and minimal residue. It has the broadest operating range, from -40° F to 1250° F, and its auto-ignition point is above 1300° F (704° C).

No matter the testing environment or application, it’s likely that Echo Ultrasonics has — or can develop — just the right couplant. Give the Echo experts a call to find the right couplant for your needs or to request a sample.
