Applies To Product(s): AutoPIPE Version(s): ALL; Environment: N/A Area: Original Author: Bentley Technical Support Group Date Logged & Current Version Nov. 2016 10.01.00.09 Problem: Why does Max Ratio = 0.00 and Notes = Fail for flange in AutoPIPE Flange analysis module? Example: And Report Shows: A N S I F L A N G E C H E C K Point Load Reaction Force Moment Press. (MPa ) Press. name combination (mm ) (N ) (N.m ) Actual Allow. Ratio ------ ---------------------- -------- ------- -------- ------- ------- ------- AO02 Class = 150 (B16.5 2009), Material Group = 1.1 (^^^)NOTE: The allowable pressure for all load combinations have been modified from the original B16.5 data. The allowable pressure has been defined by the user. Why and how to Avoid it? Solution: There could be a number of reasons for this to occur. This may be an iterative operation requiring more than one solution listed below: Solution #1: Confirm that on the Non-Code combination dialog that all combinations have the Print flag enabled / checked ON. Open Flange Analysis module and press the Analyze button again. If all the other flange information is completed than the Max Ratio should be grater than 0.00 Solution #2: Using AutoPIPE v.10.01.00.08 where Flanges max ratio was blank and physically connected to a valve or have any type of extra data assigned may be affected by a known error; Defect 263628 see here .
