Abstract

Basing on the reports on AE testing by Physical Acoustics Ltd. as well as laboratory and field experiments by OAO Slavneft'–Megionneftegaz, a technique has been developed for AE tests of bottoms of welded vertical tanks (WVTs) for oil and oil derivatives. This approach allows the engineers to assess rapidly conditions of WVT bottoms without interrupting their operation by measuring the corrosive activity of AE sources. Empirical functions describe the average activity of AE sources versus the rate of local corrosion in tanks build for various purposes and strongly damaged by corrosion, which is the major cause of leaks in bottoms of WVTs for oil and oil derivatives.
