Demonstrating the reliability of existing pipelines under new loading conditions requires the use of standard methods that have known applicability to that type of pipe and data relevant to the pipe. Both of these may be lacking for early generation…
Pipeline fitness-for-service and maintenance prioritization both require knowledge of the line pipe’s mechanical properties and fracture resistance. This report presents such information for a broad range of steels, including vintage Grades A and B…
Girth welds are an essential part of every transmission pipeline. With much of the pipeline system in the United States having been installed before 1970, concerns may exist with some pipeline companies regarding the integrity of vintage girth welds.…
A review was performed of the currently known in-service performance, integrity concerns, and methods of assessing the integrity of vintage pipelines containing girth welds made by the shielded metal arc welding process. The scope of work included…
