At table 1-100 (Appendix 1 ASME Mandatory Appendix 1 of ASME Section II) we see average stress to cause rupture at the end of 100,000 hr. Our design/rupture life (200,000 hrs.) We can find values for SA-516 Gr.70. At ASME Sec III Div 1 Subsection NH (ASME Sec III Div 5) we can't find values to...

Dear 1. Design preassure code ASME VIII Div.1 2021 2. Сladding layer 410S. 3. Design temperature is 475C, sorry for misleading you. 4. We think that the specified calculation with the specified parameters corresponds to a service life of 100,000 hours (approximately 13 years). For devices with...

We have the strength calculation at fractionator column (operating temperature 475C) for 200,000 hours of operation, but manufacturer use table 1a from ASME II D maximum allowable stress values for SA-516 Gr.70 - 45.5. (Don't include time dependent properties such as creep fatigue and creep...
