ECHOTRACE HT-170: New High-Temperature Coupling Agent

Many of our customers inspect components or piping elements that cannot be completely switched off or cooled down due to their operating condition. This is a challenge for the ultrasonic coupling.
The coupling agent should ensure a good sound transmission. At the same time, it must not become too thin at higher temperatures. The disadvantage of such hightemperature coupling agents is that they are often difficult to handle at room temperature due to their high viscosity.
This is where the new coupling agent ECHOTRACE HT-170 from KARL DEUTSCH comes in: As the name already indicates, it can be used up to a temperature of 170 °C – for a short time also at somewhat higher temperatures; this has to be tested on a case-by-case basis.
One of the first customers is wesernetz Bremen GmbH, which uses the agent to inspect the pipeline systems while in operation. Our ultrasonic flaw detector ECHOGRAPH 1095 is also used there.



Since its foundation in 1949, the owner-managed company KARL DEUTSCH has been engaged in the development and manufacture of equipment for non-destructive material testing. Mobile testing devices, stationary testing systems, sensors and chemical crack detection media for the testing methods UT, MT and PT are manufactured in two plants in Wuppertal by 130 motivated employees. Another 20 employees in foreign offices and a worldwide dealer network support the export business, which accounts for more than 60% of the turnover. Characterized by continuous innovation and reliability of the products, the brands ECHOGRAPH, ECHOMETER, LEPTOSKOP, DEUTROFLUX, FLUXA, KD-CHECK and RMG are internationally known today.
