The following is displayed in model consistency check report:
W726-8: Kink in straight run of xx deg at point XXX
Note: angle may change but uses the same avoidance measures.
Note: Some codes have an allowance for size of angle alignment along a pipe (ie. Kink angle), while individual companies may have procedures on how to deal with kinks (see project Piping Spec or Design Spec documents), In regards to AutoPIPE, analytically, kinks would simply be two connected straight pipes and would be analyzed as such. The analysis results may calculate lower stresses as compared to applying a bend where a stress intensification factor would have been applied. Ultimately it is up to the user to decide what size kink angles are acceptable in a model. Otherwise, suggest to model kink locations as a smooth radius bend or miter bend to account for any SIF factors.
This warning message is displayed whenever the incoming pipe axis does not exactly match the out-going pipe axis in a absolutely straight line through the indicated node point.
Select the indicated node point and change to a Bend point, Modify> Convert Point To...> Bend.
Note: if you are modeling with ASME B31.1 or B31.3 consider using ASME B31.j option. See AutoPIPE help for details on this feature.
User is trying to model a piece of equipment with piping and assign "Rigid Properties Over Range". If this is correct, review the indicated node point to be sure warning message can be ignored.
Select the indicated node point and Delete it from the model.
Model as a miter bend, See AutoPIPE help for details on this topic and / or modeling approach here.
Do nothing and accept the warning, not recommended, but under certain codes a slight bend of a few degrees (< 3deg) is acceptable without any special modeling required. See WIKI post here
