The following warning message is shown:
---------------------------Warning---------------------------W97-213: Corroded thickness is required for sustained stress in B31.3 ---------------------------OK ---------------------------
This message is being displayed as warning to the user that the piping code requires the use of Corroded thickness, but the program can use the Nominal thickness instead. Also the following message is shown at the end of the output report:
Warnings: (1) Sustained stress is using nominal thickness and code requires corroded.
The "Use nominal thickness" on the Results Model Options dialog screen controls the wall thickness used during the code calculations. See the online help for details on this setting (note - see Definition of Terms> Pipe Properties, for definitions of tnom, tcor, or tred)
