Problem:

How to calculate the ISO 14692 allowable?

There is no place to enter the f2 and f3 values or thermal expansion coefficient.

Solution:

Please see the following AutoPIPE help section for general Code equations used by the program:

Help > Contents> Contents Tab> Reference Information> Code Compliance Calculations> ISO 14692> select a topic (ex. Allowable Stresses) 

The expansion coefficient, along with other ISO 14692 specific inputs, are located on the Operating Pressure and Temperature dialog box:

Select All or part of an open model that is using ISO 14692 piping code and under Modify> Operating Pressure and Temperature> enter values as needed:

The f2 factor for the 3 different stress categories is found in the Results Model Options (Tools>Model Options>Result) dialog box:

As for the expansions allowable:

AutoPIPE does not calculate the expansion allowable for ISO 14692, as this allowable is not provided by the code.  Only option to enter in a user allowable for any expansion cases by going to the Load Combination  (Tools>Combinations) dialog box, unchecking “Auto Update” in any expansion case and inputting the allowable values based on the units for that column.

Note: It would also be helpful for you to go through the new Nonmetallic Piping Training video available on the LEARNserver.
