... of the total defects are monitored during each inspection campaign, and a high-risk defect could be missed completely. Through the use of laser scanning techniques, this work develops an automated approach to measuring the height of blistering corrosion or depth of surface pitting. A workflow is suggested...

A study was undertaken to provide an assessment of the state-of-the-art of preventing or minimizing the deleterious effects of these phenomena in the transmission of sour (H2S containing) gas. This investigation was undertaken...
