Abstract

Plant and feedstock stability is an important factor in ensuring consistent production volumes and minimal maintenance intervention, especially in the petrochemical industry. Thus, detailed design and in-line inspections of mid-stream equipment; such as underground pipelines are critical to reduce the risk of failure due to pre-existing or newly developed defects. Elongated external metal losses, assimilated to crack-like defects in some circumstances; can significantly impact the integrity of pipelines thus inline inspections are important to identify and implement remediation activities. ASME B31G provides guidelines to determine the estimated failure pressure in pipelines that have defects present. In this paper, a comparison between the estimated failure pressure based on the original ASME B31G equations and the modified ASME B31G equations were compared to a finite element model based.
