Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.
This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.
The demand for information on the status of pipelines still rises. Stringent environmental protection laws, rising insurance costs and rising lifetime of existing pipelines ask for more detailed and reliable inspection results [1,2]. An ultrasonic inspection system is developed for the assessment of corrosion in fluid filled pipelines. In this paper an overview of the measurement system is given. Special attention is paid to the measurement head and the data-acquisition unit. Application of the system for the assessment of internal corrosion damage is illustrated.
