Ultrasonic propagation along sheet steel.

Hi.

Has anyone seen any papers/studies/equipment related to transmitting ultrasonics along steel plate (1/2" to 1" thick).

I'm specifically thinking a *large* steel storage tank.

I want to inject a signal at one point on the tank and measure the signal at various other points on the tank.

I'm looking for any info/products that relate to fixed transmit 'ducers, movable receive 'ducers, signal attenuation, power levels etc.

Examples of practical components would be FANTASTIC.

Thanks....

Hi,
Sounds like you need to be looking at Guided Waves Ultrasonics in this application.
Guided waves can propagate along plates (and pipes) for hundreds of feet, and can detect defects typically with a single number of percent of wall thickness reduction.
The waves travel through (butt) welds (but will have difficulty on lap welds on tank floors)
Please contact me and we can give you more information about this.
