Abstract: A LARGE PORTION of pipelines in the United States were installed prior to the enactment of federal regulations in 1970s. The girth welds of these pipelines were not 100% non-destructively inspected at the time of construction. These welds may contain flaws that could lead to occasional failures when additional stresses beyond those stresses under normal operation conditions are present. Recent accidents associated with vintage pipelines elevate the public attention and highlight the needs of integrity management of these pipelines. Due to the low frequency and high consequence of those failures, an effective management plan is necessary to direct the limited resources to the welds of the highest potential risk.
