The only time the required thickness must be entered is if the component being analyzed is a bolted flat head. Otherwise, the required thickness of the shell/head will be computed by the program.
For hillside nozzles, as of Version 5.40, several changes have been made relating to the use of the required thickness. They are as follows:
-
If you want to enter an offset and allow CodeCalc to compute the nozzle angle, the required thickness must be left blank.
-
If an angle less than 90 has been entered, or computed via the entered offset values, and you would like to take credit for the Code 0.5 F-correction factor, the required thickness must be entered in and multiplied by the F factor.
-
If an angle less than 90 has been entered and you do not want to take credit for the Code 0.5 F-correction factor, the required thickness should be entered.
