Pipeline is the main manner to transport oil and gas from one place to another. Oil-gas pipeline is built rapidly in the last decade in China. At the same time oil-gas pipeline accident threatens the person's live and property. Corrosion is one of the main reasons that affect the oil-gas pipeline safety operation. Pipeline corrosion damage quantitative risk analysis is carried out on the basis of pipeline function equation and detecting data. The effect of the related parameters uncertainty on the analysis results is resolved by Monte-Carlo method. Then risk value of the pipeline segment is gotten. It has significant...
