Development of Comprehensive Pressure Test Design Guidelines - Task 6: Pressure Test Evaluation Guidelines

The objective of this project is to develop comprehensive guidelines for the design of pressure tests that could be incorporated into industry standards such as ASME B31.4, ASME B31.8, ASME B31.8S, and/or API RP 1160. These standards have for many years provided valuable test guidance and requirements, but they may not reflect the most current knowledge and industry needs in this regard. It is expected that the proposed work will draw heavily on what has been learned by pipeline operators and pressure-testing contractors who have performed pressure tests on thousands of miles of pipelines. The work also will take into account the significant amount of research on pressure testing that has been carried out from the 1960s through the present by the Pipeline Research Council International (PRCI), the Pipeline and Hazardous Materials Safety Administration (PHMSA), and other organizations. In particular, the recent work sponsored by PHMSA on the behavior of Electric Resistance Welded (ERW) pipe and on repair/replace considerations for pre-regulation pipe will be considered with respect to implications for best testing practices. The key design aspects of pressure test evaluation covered by this document include: statistical distribution of pipe material properties, potential for and effects of yielding, criteria for acceptable limits on pipe expansion, reassessment intervals for various time dependent defect growth mechanisms, longitudinal seam failure susceptibility analysis, and the use of pressure testing to validate the results of in-line inspections (ILI).
