How does B31.3 2014 affect CAESAR II?

The 2014 Edition of B31.3 includes a number of modifications that affect CAESAR II. Users need to be aware of these changes to properly use CAESAR II to meet these revised requirements. These changes are available in the upcoming release, CAESAR II 2016, Version 8.00.
  • The B31.3 code standard committee removed Appendix P from the 2014 Edition and incorporated several requirements of Appendix P into other sections of B31.3.
  • Perhaps the most significant CAESAR II change resulting from the 2014 Edition is the treatment of the stress due to sustained loads, SL, in setting the more-rigorous Allowable Displacement Stress Range (SA) (found in paragraph 302.3.5.d). The code now states that ”in systems where supports may be active in some conditions and inactive in others, the maximum value of sustained stress, considering all support conditions, shall be used.” 

    CAESAR II 2016 incorporates a new load case format that enables the designer to calculate sustained stresses based on the support configuration associated with any operating state of the piping system.
  • The 2014 Edition also introduced the requirement to evaluate four-thirds of the design cold spring, in addition to the current requirement of two-thirds. CAESAR II can easily accommodate this new requirement by applying a multiplier to the CS load primitive.
The good news is that CAESAR II 2016 addresses all of these new B31.3 code requirements. Upgrading to this release positions you on the forward edge of the latest code revisions, and gives your business a competitive edge.

Where do you spend the most amount of  time after you have performed your CAESAR II stress analysis?
  1. Generating reports.
  2. Verifying stress on equipment such as on vessels, pups, turbines.
  3. Generating Stress Isometrics or drawings.
  4. Additional documentation.
  5. Something else. (Please specify.)
