High impedance epoxy/glue

Does anybody know of epoxy/or glue with high acoustic impedance?

Thanks!

Re: High impedance epoxy/glue
Dear Peter,

You might consider filling the glue with fine heavy particles to increase the densitiy and perhaps the stiffness a little bit as well. I think wolfram is sometimes used for this. Of course, the particles need to much smaller than the wavelength of the ultrasound used to avoid scattering and damping. You might consult Precision Acoustics in England, www.acoustics.co.uk might be able to help you.

Regards, Elmar

Extended Range Variable Wall® Piping Calibration Blocks for Longseam Inspection

...
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.
