Full-Text - Abstract

Increasingly, pipeline and plant operators apply non-destructive testing (NDT) as an economic tool to establish the condition and integrity of their equipment and components, whether or not applying risk based inspection (RBI) philosophy. Results are used for predictive maintenance and life-time extension programmes. This approach often requires more surface coverage of the selected location than can be achieved by common spot-check inspection techniques. Full-surface coverage with NDT inspection is often prohibited due to unsuitable methods which are slow and hence too expensive. This created the demand for the so called screening tools with which suspect areas can be detected very rapidly. In recent years several of this methods have entered the market. In the paper two methods will be discussed that can be applied on carbon steel components. The first method is based on magnetic flux leakage (MFL) and is suitable for inspection of painted or coated but non-insulated components. The second method is a pulsed-eddy current technique called Incotest which can be applied on thermally insulated components to measure average wall thinning due to corrosion under insulation (CUI) or detect erosion. Both methods will be explained and examples of use will be given.
