The Pipeline Safety Improvement Act of 2002 requires that operators (1) assess gas transmission pipeline segments in about 20,000 miles of highly populated or frequently used areas by 2012 for safety threats, such as incorrect operation and corrosion…
Describes the principal types of problems that pipeline operators can expect to have with pipelines comprised of older pipe materials with electric resistance welded (ERW) seams. It also provides some suggestions for continuing to operate such…
A review of the quality of' some manufacturers' ERW welding processes and the future reliability of pipeline segments containing defective ERW seam welds. This technical report, which is based on the OPS accident information database and other…
Describes the development of an automated system that can effectively replace the EPA-mandated in-service and out-of-service inspections of the Internal Floating Roofs (IFR) in Aboveground Storage Tanks (ASTs). The ultimate goal is to increase the…
PRCI research project, EC-4-6 Improving Corrosion ILI Sizing Models for Long Complex Corrosion Anomalies (Koduru 2018), performed by C-FER Technologies (1999) Inc. ("C-FER"), involved collecting in-ditch high-resolution laser scan records,…
The PRCI project IM-3-1 "Performance Capabilities Evaluation of ILI for Long Seam Features in ERW Pipe" is part of an integrated multi-year, multi-phased program and systematic approach for evaluating the performance capabilities and limitations of…
While the general fracture mechanics methodology for calculating fatigue lives is well documented and validated, its application in the definition of pipeline system fatigue lives have differed from field experience. The source and magnitude of the…
The purpose of this project is to provide technical support in the areas of pipeline safety and integrity management. The goal being to improve pipeline safety for the benefit of the general public, company employees and the environment. This report…
Postweld heat treatments originally were applied to improve the strength and toughness of the weld. Recent information has indicated that postweld heat treatments also can have a significant effect on the resistance of the weld line to selective…
A notched-tensile test procedure was developed that requires two test specimens, a side-notched transverse flattened strap and an unnotched axial specimen. The weld ductility is defined in terms of the ratio of the notched to unnotched tensile…
