Abstract

Reliability of equipment used in the oil and gas industry is critically important. In pipeline transmission systems, corrosion threatens pipeline integrity.  Researchers used reliability analysis based on modeling corrosion degradation ratio as determined by the amount of the corrosion rate externally and internally.

They determined that internal corrosion has a major contribution to the remaining life of pipeline. From the calculation results obtained by external corrosion has the greatest reliability over 60 years, followed by internal corrosion less than 30 years and the least is by cumulative corrosion which is less than 20 years.
