The following error message appears in the output report:
The thickness of the neck of tubing is not sufficient according to UG - 45.
How to fix and avoid this issue.
Answer:
In both cases the tolerance must be taken into account.
In the first case, the tolerance (as a value) is added to the corrosion (as usual in AutoPIPE Vessel), so this is the value Can = 4.558 mm which is used in accordance with paragraph UG-45.
In the second case the value obtained by the application of UG-45 does not take into account the tolerance% because it can only be applied when the required thickness is known, that's why tUG-45 value should be increased to take into account the tolerance of 12.5% (11.34 / 8.75 = 12.96 mm) and compared to the nominal value of the thickness of the nozzle neck (12.7 mm). Similarly this tolerance is applied to the required thickness under internal pressure trn (non-dimensioning in this case).
