It has been reported in industry that recently manufactured piping and pressure vessel components may have reduced toughness where the component fails the Code -20F impact exemption. This presentation will review the industry reported findings and outline a potential analysis path forward to address fitness for service (FFS) concerns for potentially at-risk components that are currently in service. Representative analysis results for various configurations will be presented along with highlighting the need for further industry work to develop a methodology to identify the systems with the highest risk for brittle fracture if these reduced toughness components are within the system.
