Question:
What does this warning mean when shown in my AutoPIPE Vessel report:
23 Tubesheet Loading conditions 1 [corroded normal condition]: Scope requirements not maintained
Answer:
This warning message is specific to a heat exchanger model constructed with AutoPIPE Vessel. The warning message informs the user of an issue with a calculation that requires attention. In order to find the offending calculation, open the heat exchanger MS Word output report warning section, and press on the Hyperlink text.
Example:
23 Tubesheet Loading conditions 1 [corroded normal condition]: Scope requirements not maintained
(hyperlink above is for show only)
After locating the offending section of the output report, review the entire section and find red text "not maintained", located next to a calculation requiring attention.
In this example, the code has specific requirements that must be maintained: Gc must be greater than 0.9Ds and less than 1.2Ds. However, when this values are calculated, Gc is outside the range:
-
-
- Ds = 303.6
- Gc = 365
- 0.09*Ds = 273
- 1.2*Ds = 364
-
Avoidance options
-
-
- Accept the warning and do nothing.
- Make the necessary setting changes in the model that will affect the calculation not maintained.
