Proceedings Papers

Proc. ASME. IPC2022, Volume 1: Pipeline Safety Management Systems; Project Management, Design, Construction, and Environmental Issues; Strain-Based Design and Assessment; Risk and Reliability; Emerging Fuels and Greenhouse Gas Emissions, V001T08A006, September 26–30, 2022
Publisher: American Society of Mechanical Engineers
Paper No: IPC2022-87069
... of fracture toughness and fatigue, through embrittlement or hydrogen induced cracking. Fracture toughness as a measure of crack arrest performance through required Charpy (TCVN) performance represents a principal mechanical property requirement of the pipeline. Ductility performance, regardless...

Proc. ASME. IPC2020, Volume 3: Operations, Monitoring, and Maintenance; Materials and Joining, V003T05A008, September 28–30, 2020
Publisher: American Society of Mechanical Engineers
Paper No: IPC2020-9789
... Abstract In recent years increased attention has been given to the transferability of standardized fracture test data to thin-walled pressurized equipment. For smaller diameter piping, for example, standard test specimens loaded in “hoop” tension are not possible due to pipe curvature...

Publisher: American Society of Mechanical Engineers
Paper No: IPC2012-90236
... of the calculations to the calculation method used and to the input data, such as flaw profile, are examined. The results provide useful guidance to all those involved in predicting failure pressures as part of their threat management activities. Keywords: stress-corrosion cracking, fracture, failure pressure...

Proc. ASME. IPC2008, 2008 7th International Pipeline Conference, Volume 2, 93-101, September 29–October 3, 2008
Publisher: American Society of Mechanical Engineers
Paper No: IPC2008-64059
..., and then applied the preliminary failure assessment to the spiral welded defects of oil pipeline, with the use of ultrasonic inspection data of Daqing-Tieling old pipeline from LingYuan to XinMiao, Northeastern China. The calculation of both fracture and plastic collapse failure for spiral welded defects indicates...

Proc. ASME. IPC2004, 2004 International Pipeline Conference, Volumes 1, 2, and 3, 1833-1842, October 4–8, 2004
Publisher: American Society of Mechanical Engineers
Paper No: IPC2004-0422
... fracture mechanics analysis was developed using the T-stress approach. Cracked body finite element analyses were used to obtain the T-stress for a range of surface breaking and buried defects in typical linepipe geometries. The results from these models were used to develop a constraint modified Failure...

... of ductile fracture referenced to peak pressure and hold-time, and then contrasts these to the response in low-toughness situations. Fracture properties typical of an early-vintage electrical-resistance weld (ERW) seam were determined and used as the basis to simulate the response at toughness levels typical...
