Does anyone happen to know when the next ASME B31 revision is planned? Particularly B31.3. We are interested in adding this to our U stamp for PVs and I'm curious what the revision timeline is like for this one when compared/added to the BPVC.
Key changes to this revision include:
1) Additional of Appendix W – High Cycle Fatigue Assessment of Piping Systems
2) Metric conversion added for Table C-6, Moduli Table
3) Metric conversions added for Appendix C Thermal Expansion
4) Major updates to the stress tables in A-1, A-1M, K-1
5) Para. 323.2.2 Rules for Impact Testing of Materials was updated to correct inconsistencies, and incorporate current approaches to impact testing exceptions of materials
6) Reference to the new B31J-2017 added
7) Allow alternate rounding approaches for units of measurement
8) Update the Larson Miller constant for Grade 91 (9Cr-1Mo-V) material
9) Update Appendix D – Flexibility and Stress Intensification Factors
10) Add titanium Grade 12 to Table A-1 and Table A-1M
