New guidelines promise more accurate damage assessment

Abstract

Results of research have significant implications for line-pipe corrosion assessment. Burst-test data from NOVA's research have led to more accurate damage-assessment guidelines which, if employed, could prevent unnecessary and expensive pipe repair or removals. The objective of the burst-test program was to verify the defect-acceptance criteria for the following different types of flaws: longer than 1D, spirally oriented, and interacting. The results of the burst tests are discussed.
