The following message appears during a Model Consistency check report:
* * * W A R N I N G - MODEL * * *
W726-55: Creep data for (XX) is above temperature range. Zero allowable used at point (YY) for material (ZZ)
How to avoid and fix it so it does not appear?
Reason A.
This issue is specific to those piping codes that have a creep data table in their library (ex. En13480).
According to the Library data and material properties specified, temperature load case(s) may be requesting a library value that is outside of the range of data in the library.
Review the material library to confirm data temperature is within the data range specified in the library.
Example: En13480, Creep Table, searching for GRP_1-5.2, 16Mo3
A. Start AutoPIPE, and select Tool> Library> Table type = Creep, Library name = Euro2012, Action = Scan:
Press OK button
B. AutoPIPE Viewer appears with the Euro2012.Lib Creep data only. Review the data as needed.
Note: the library values account for the SFcr factor, where the Input grids does not (ex. 20 x 1.25 = 25)
C. Review Press/Temp/PipeID tab on the input grid, Note that FCr is 0.00 for 560 deg C but for 550 deg C Fcr = 20.00
Another words when temp = 550.1 deg C or higher, it means that the material is outside of its range. Range for this example is exactly 450 to 550 deg C. Anything not with in this range is considered out of range.
The following may appear on Code Stress floating dialog:
Reason B
Review Tools> Model Options> Results> Use min(f;fcr) for Hoop, Confirm feature is un-check / disabled. See AutoPIPE help fro details on this feature. Fcr can be calculated as 0.00. Thereby causing this Warning / Note to appear.
