Dear Friends,
Here I put some queries what we had checked with CODE 31.3 2012.
1)Clause 302.3.5 - Allowable Displacement Stress Range.
Sc = 138 MPA & Sh =138 MPA.
Also, mentioned as "MAXIMUM".
== The Value of SC & Value of SH were not given in code 2010.
== Does it affect to allowable SA?
== Do we have to input any value in CAESAR?
SA = f(1.25Sc+0.25Sh)
= 1.2 (1.25 * 138 + 0.25 * 138)
= 248.4 MPA
Is this Maximum Value?
== From Where these values are derived based on Yield or Tensile?
2) Clause 319.3.6
Stress Intensification Factors may be developed in accordance with ASME 31J.
== Request if any one expert has some overview/idea how to calculate SIF based on 31J, please share here.
3) Clause 319.2.3
(c) Average Axial Stress - for Buried,core-jacketed etc.
== This point has been added in 2010 for checking Axial
Stresses, however it has been removed from ASME Code 2012.
== Does it mean now all calculations need to consider Axial Stress (all piping)?
Friends, wishes to have a reply / suggestion here.
Regards
SND.
