Flexibility factors and stress indices for piping components with D/T ge 100 subjected to in-plane or out-of-plane moment
- Kobe Steel Ltd., Kobe City (JP)
The finite element analyses are carried out for the several piping components (D/T{ge}100) subjected to in-plane or out-of-plane moment. For the stress evaluation of the chemical plant piping systems, ANSI B31.3 is usually applied. But the stress intensification factors and flexibility factors in this code are mainly for a heavy-wall-thickness pipe, so it is necessary to reconsider these factors for a thin-wall-thickness pipe with a large diameter. In their study, several finite element analysis using MSC/NASTRAN program were performed on the pipe bends and the unreinforced fabricated tees. The empirical formulas for the flexibility factors and the stress indices, due to out-of-plane or in-plane moment, are proposed.
