Abstract

This report describes experimental and analytical efforts to evaluate fracture of stainless steel flux-welded pipe. Seven pipe fracture experiments (four with through-wall circumferential cracks and three with circumferential internal surface cracks) were conducted at 550/sup 0/F (288/sup 0/C). Material characterization efforts involved laboratory specimen tests to assess specimen size effects, effects of solution-annealing, and crack-growth behavior in the HAZ, along the fusion line, and in the weld metal. Efforts involved assessing the net-section-collapse analysis, the plastic-zone screening criterion, inherent safety margins in the IWB-3640 flux weld analysis, through-wall-cracked pipe predictive J-estimation schemes for LBB analyses, eta-factor J-R curves calculated from the pipe experiments for comparison to C(T) specimen results, and finite element analysis of C(T) specimens and one pipe experiment. This report also evaluates the technical significance of these results and their significance relative to licensing decisions.

Experimental and analytical assessment of circumferentially surface-cracked pipes under bending

Technical Report Scott, P; Ahmad, J

This study was performed to assess the validity of various techniques to predict maximum loads for circumferentially surface-cracked pipes under bending. Experimental data were developed for both carbon steel and stainless steel pipes. Predictions of maximum loads were made using the net-section-collapse method, the IWB-3640 analysis procedures, and a newly developed finite-length surface-cracked pipe J-estimation method. The net-section-collapse method gave good maximum-load predictions for certain types of pipe. However, for pipes with large radius to thickness (R/sub m//t) ratios and/or low toughness this analysis method tended to overpredict the experimental maximum load. A plastic-zone screening criterion was developed to showmore »« less
fracture analysis. Volume 1 of welded type 304 stainless steel pipe. J-R curve characterization and limit load analysis

Technical Report Hays, R; Vassilaros, M; Gudas, J

An experimental investigation was performed to determine the fracture resistance of 4 in. diameter circumferentially welded type 304 stainless pipe at 288/sup 0/C (550/sup 0/F). Two crack geometries were investigated. These were a circumferential through wall crack (simple) and circumferential through wall crack superimposed on a 360 degree radial crack on the inside diameter of the pipe (complex). Test results were analyzed using J-integral and limit load techniques. Additionally, J-integral resistance curve tests were performed on large plansize compact tension specimens for comparison with the pipe specimen results. Results of the J-integral analysis indicate that J-initation for pipes containing simplemore »« less
Short Cracks in Piping and Piping Welds. Semiannual report, October 1991--March 1992: Volume 2, No. 2

Technical Report Wilkowski, G; Brust, F; Francini, R; ...

This is the fourth semiannual report of the US Nuclear Regulatory Commission`s Short Cracks in Piping and Piping Welds research program. This 4-Year program began in March 1990. The overall objective of this program is to verify and improve fracture analyses for circumferentially cracked large-diameter nuclear piping with crack sizes typically used in leak-before-break analyses or inservice flaw evaluations. Progress during this reporting period involved: (1) completing two through-wall-cracked pipe experiments and supplementary material property data, (2) an internal circumferential surface-cracked pipe experiment was completed which showed that the R/t effects on the Net-Section-Collapse Predicted loads for surface-cracked pipe tomore »« less
Evaluation of flaws in ferritic piping: ASME Code Appendix J, Deformation Plasticity Failure Assessment Diagram (DPFAD)

Technical Report Bloom, J

This report summarizes the methods and bases used by an ASME Code procedure for the evaluation of flaws in ferritic piping. The procedure is currently under consideration by the ASME Boiler and Pressure Vessel Code Committee of Section 11. The procedure was initially proposed in 1985 for the evaluation of the acceptability of flaws detected in piping during in-service inspection for certain materials, identified in Article IWB-3640 of the ASME Boiler and Pressure Vessel Code Section 11 Rules for In-service Inspection of Nuclear Power Plant Components.'' for which the fracture toughness is not sufficiently high to justify acceptance based solelymore »« less
Degraded Piping Program - Phase II. Semiannual report, October 1985-March 1986. Volume 4

Technical Report Wilkowski, G; Ahmad, J; Barnes, C; ...

The efforts in this report are broken into nine work packages related to pipe-fracture research efforts and three work packages that are supporting research efforts. The pipe-fracture efforts involve only circumferential crack orientations. Forty-two pipe experiments have been conducted to date, with all but two at 550/sup 0/F (288/sup 0/C). Approximately 42 additional pipe experiments from other programs were also analyzed. In the analysis effort, a screening criterion was developed to show when the net-section-collapse analysis is valid. This shows that even wrought stainless steel can fail at less than net-section-collapse loads if the pipe diameter is sufficiently large. Numerousmore »« less
