In the technical paper "New Piping Flexibility Rules
in ASME B31.3, Appendix P" authored by Charles Becht IV & David W. Diehl, In the load case definitions, Strain range between operating and cold shutdown positions are shown like ( W+T1+P1)-( W+T2). Why is it not ( W+T1+P1)-( W+T2 +P2).Need clarification from seniors.
Regards,

Are you talking about Appendix P in 31.3 2004?

the dude,

I am refering to technical paper "New Piping Flexibility Rules in ASME B31.3, Appendix P" by Charles Becht, IV and David W. Diehl
J. Pressure Vessel Technol. 128, 84 (2006)

What is "P2" defined as? I assume if it's cold shutdown condition, then pressure would be 0 and thus not needed. (I haven't read the paper, so keep that in consideration).

-Shannon

P2=0 so it is not needed in the cold shutdown load case.

The Example 1 model used in the PVP paper came from B31.3 - 2004 Appendix S.
