Problem:

The following screen appears when entering in a Inside diameter value in AutoPIPE's Flange Analysis software:

---------------------------
Flange*
---------------------------
The value must be equal to the inside diameter of the pipe.
---------------------------
OK
---------------------------

Why and how to avoid it?

Solution:

As the dialog indicates the user must enter the exact inside diameter of the pipe where the flange is located. Exit the flange analysis, locate the flange, note the segment name and PIPE ID of the node point, review the Pipe ID for the Pipe OD and Wall thickness. Solve for inside diameter,

Re-open the Flange Analysis module, select the Flange tab, locate the correct flange row, and enter the Inside pipe diameter calculated above.

Known Issues:

However, there is a known issue, column units must be inches. If using mm units, the warning message above will keep appearing. The following has been logged and will be fixed in a future version of the application:

Defect 641777: Nominal Standard Pipe OD greater than 900mm is not accepted during dimension library selection

Avoidance:

Set the model input unit file to AutoPIPE, then set the outer diameter of the pipe in question to the appropriate standard OD. Finally, set the input units to the desired file. DO NOT touch the OD dialog again.

Another known issue occurs when the Flange / Bolt Dimension is set to NS that a user may not be able to enter a value.

Defect 641778: Inside diameter data from the flange analysis dialog may not be enterable by the user for NS flanges

Avoidance:

Convert the model input and output units to AutoPIPE (ENGLISH). For the offending node(s), open the corresponding pipe properties dialog and update the actual OD and thickness to match the dimension requirements of the flange. After updating all pipe properties needed, run the model analysis and open the flange dialog.
Navigate over to the flange tab and update the inner diameter column to match the dimension requirements of each flange. No error dialogs should show if done correctly. Run flange analysis.
