Introduction of Hubert Velten, Supervisor of Mechanical Engineering
Setting: ASME event at Shell Energy Transition Campus, Amsterdam
00:00:24 - 00:01:26
Purpose of the ASME B31.3 committee meeting in Europe (first time outside the U.S.)
Goal to increase global participation in piping code development
00:01:26 - 00:02:05
Hubert’s role in revising Appendix N of ASME B31.3
Appendix N’s focus: Bridging ASME B31.3 and the Pressure Equipment Directive (PED)
00:02:05 - 00:03:44
Differences between ASME and PED frameworks (e.g., welder certification, conformity assessments)
Hubert’s motivation to expand Appendix N based on 15 years of field experience
00:03:44 - 00:05:16
Joining the ASME International Review Group (Subgroup N)
Process of proposing changes to the code via consensus and ballots
00:05:16 - 00:07:07
Key challenges when combining ASME B31.3 and PED:
00:05:58: Third-party certification of welders (notified body involvement)
00:06:34: Conformity assessment requirements under PED
00:07:07 - 00:10:53
Behind-the-scenes of ASME code revisions:
00:07:16: Timeline from idea to implementation (~2.5 years for Appendix N)
00:08:00: Balloting process and committee approvals
00:09:11: Role of ANSI in final approval
Closing remarks on the value of global standards collaboratio
