ASME B31J-2017
Stress Intensification Factors (i-Factors), Flexibility Factors (k-Factors), and Their Determination for Metallic Piping Components
This Standard sets forth an engineering procedure deemed appropriate for the determination of the fatigue capacity of a piping component or joint in most services, relative to a standard butt-welded joint. The B31 piping Codes provide stress intensification factors for the most common piping components and joints. This Standard presents an experimental method to determine stress intensification factors.
