Using instrument scraper surveys for corrosion repair
- Aramco (SA)
This paper reports on a program for overall pipe line repair. This program was implemented to maintain pipe line integrity and for identifying problem areas which require reconditioning or replacing by: reviewing pipe line leak history; checking periodically lifetime expectancy and integrity of pipe coatings; using cathodic protection annual survey results to locate low potential areas (close-interval survey is needed to identify the exact location of corrosion); and hydrotesting the pipe line (using leaks or ruptures from the hydrotest to identify problem areas). The pipe line revalidation plan is insufficient for identifying pipe line leaks. Instrumented pig testing provides more accurate and reliable ways of testing the pipe line for internal or external corrosion or defects.
