Couplant Free Transducers (2 - 5 Mhz)

Would like to hear about anyone's experience applying "Couplant Free Transducers". Specifically “wheeled transducers in the 2 – 5 Mhz range. We are currently considering using this technology and want to hear pro's and con's. Would be grateful for any feedback, positive or negative.
Regards, Rich Roberts

Re: Couplant Free Transducers (2 - 5 Mhz)
Silverwing makes an extremely rugged and HIGH PERFORMANCE wheeled transducer which is available in several versions of products made by both Silverwing and NDT Automation. These includes both manual B-Scan and C-Scan systems as well as fully AUTOMATED, high-speed C-Scan systems.

There are technical differences between conventional pulse-echo transducers and wheel transducers - which are essentially dual-element designs - which can be an issue for SOME applications - but for most situations - the "only" difference is the fact that the wheeled design can be used WITHOUT COUPLANT. (For extremely corroded materials with significant FRONT SIDE corrosion, a standard - water coupled - pulse-echo design will provide somewhat better performance - and that factor would be the "only" operational limitation). The up-side (of course) is the operation of these transducers without the need for water or gel couplant.

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

This set of two blocks has been specially designed for situations where ultrasonic examination tak
...
es place circumferentially or “around the curve” for applications such as inspection of longseam welds in piping and vessels. Jointly designed by PH Tool and Holloway NDT, the blocks feature side-drilled hole reflectors positioned within novel compound-curves, each with multiple thickness steps. The unique design results in a light and compact form factor, with the largest block weighing just over 15 lbs and spanning just 16 ¾”. Coverage is provided for nominal pipe sizes from 6” to 10” in the small block and 12” to a whopping 56” in the large block. The compound OD curves and multiple wall thicknesses actually exceed ASME requirements, providing exceptional signal response and measurement accuracy. Properly managing beam divergence off the ID and stabilizing beam skew due to probe rocking is essential to maintaining a consistent calibration when inspecting lengthwise on curved surfaces.
