Description

The detection of corrosion defects in pipework is an extremely important topic, particularly in the oil and chemical industries. The established procedures rely on the removal of any insulation material followed by localised inspection which is extremely expensive. A cheap and rapid inspection method would therefore be of great value. Researchers at Imperial College have developed a rapid testing scheme, utilising Lamb waves which propagate along the pipe. It is essentially a pulse-echo scheme: the instrumentation is located at a single position on the pipe; it excites waves in the pipe and then receives reflections which return from any corrosion defects. Details of the development of the technique and field trials have been reported elsewhere [1–5].
