Monitoring De La Corrosion En Ligne De La Corrosion En Ligne Non Intrusif Non-intrusive Online Corrosion Monitoring

Corrosion in process industries is becoming bigger issue day by day and is also the most common cause of asset failure / forced shutdown in plants. Failure of a pipeline or vessel can be dangerous & costly and have severe environmental consequences. A typical mode of asset failure is wall thinning to a critical thickness due to erosion or internal & external corrosion. To keep track of corrosion in pipes/assets currently manual inspection and monitoring techniques are employed that are expensive and time consuming. Plus often critical measurement areas are located in difficult and or expensive to access locations that makes the inspection much more difficult. Since this data is not online, hence it is not suitable for long-term data analyses or corrosion trending. The objective of this paper is to present a new non intrusive technology to monitor corrosion, using ultrasonic, as well the use of software to store data, monitor corrosion rates and trends, allowing a repair planning before the failure happens. This paper is divided into two parts. First part will focus on different kinds of corrosion and how it happens. Second part will talk on the corrosion monitoring techniques that includes both currently used methods and the proposed UT based solution that can help in continuous monitoring of wall thickness with installed sensors & portable or installed instrumentation.
