Pile foundations

I am a geotechnical engineer in the Pittsburgh, PA area. I often have to evaluate whether the steel piles used in bridge foundations can be reused safely or if corrosion has reduced the area of steel. Is Ultrasonic testing something that could be used to help us evaluate the cross sectional area of the existing steel piles.

dear michael
yes u/t is the way to go. you have a few options, manual "A" scan, grid digital, or "B" & "C" scans that will give you a pictorial image or finally continuous monitoring ultrasonic belt attached to the pile and that can be used beneath grade

l - as well as oil and gas transportation industry. The sensor system is designed for permanent monitoring or periodic inspection tasks. Sensors are available for different AE-frequency ranges optimized for corrosion and fatigue crack detection and other applications. The ISAFE 3 sensor system consists of an AE-sensor (model ISAS3) certified according to ATEX/IEC for installation in zone 0, gas group IIC, IP68, 20 to +60 °C, and a signal isolator (model SISO3) certified for installation in zone 2. An ISAS3 sensor can be mounted in atmosphere or submerged, e.g. in water or crude oil. It is supported by mounting tools for temporary (magnets) or permanent (welded) installation. ISAFE3 supports automatic sensor coupling test and can be used with any AE signal processor supporting 28V supply at 90 mA peak, e.g. Vallen Systeme ASIP-2/A.
