RISFailure Mode and Failure Strengths for Wall Thinning Straight Pipes and Elbows Subjected to Seismic Loading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: It is important to assess the failure strengths for pipes with wall thinning to maintain the integrity of the piping systems and to make codification of allowable wall thinning. Full-scale ...
Alignment Rule for Non-Aligned Flaws for Fitness-for-Service Evaluations Based on LEFM
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: If multiple discrete flaws are detected that are in close proximity to one another, alignment rules are used to determine whether the flaws should be treated as nonaligned or as coplanar. ...
Assessment of Piping Field Failures and Burst Tests on Carbon Steel Pipes With Local Wall Thinning Using ASME Section XI Code Case N-597-2
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the more common modes of degradation in power plant piping has been wall thinning due to erosion-corrosion or flow-accelerated corrosion. Extensive work has been performed to understand ...
Prediction Method for Plastic Collapse of Circumferentially Cracked Pipes Subjected to Combined Bending and Torsion Moments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a crack is detected in a pipe during in-service inspection, the failure estimation method given in the Codes such as the American Society of Mechanical Engineers (ASME) Boiler and Pressure ...
Prediction of Fully Plastic Collapse Stresses for Pipes With Two Circumferential Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fully plastic collapse stress for a single circumferential flaw on a pipe is evaluated by the limit load criteria in accordance with the JSME Code S NA-1-2004 and the ASME Code Section XI. ...
Prediction of Collapse Stress for Pipes With Arbitrary Multiple Circumferential Surface Flaws
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a flaw is detected in a stainless steel piping system of a nuclear power plant during in-service inspection, the limit load estimation method provided in codes such as ASME Section XI ...
Effects of Torsion on Equivalent Bending Moment for Limit Load and EPFM Circumferential Pipe Flaw Evaluations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The circumferential flaw evaluation procedures in ASME Boiler and Pressure Vessel Code Section XI nonmandatory Appendix C are currently limited to straight pipes under pressure and bending loads ...
Failure Bending Moment for Pipes With an Arbitrary-Shaped Circumferential Flaw
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: When a flaw is detected in a stainless steel piping system, an evaluation has to be performed to determine its suitability for continued operation. The failure bending moment of the flawed ...
Inclusion of Torsion Loads in Section XI Flaw Evaluation Procedures for Pipes Containing Circumferential Planar Surface Crack-Like Flaws on the Basis of Limit Load Analysis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Piping systems in power plant may experience combined bending-torsion loads in the presence of planar crack-like flaws. ASME Boiler and Pressure Vessel Code Section XI nonmandatory Appendix C ...
