Problem Description

Two flanges added to a component may incorrectly share the same flange data

Reason

When inserting a valve or a flexible joint and selecting the option to add flanges to both ends, the flange analysis data would be shared incorrectly by the two flanges.For example, changing the analysis method from ASME Section VIII Div.1 to Div.2 on one flange will incorrectly update the other flange upon exiting and restarting the flange analysis.

The following considerations are provided below to assist in your evaluation of the potential impact of this defect on the flanges in your model.

1. Was the model built in AutoPIPE version v9.4.0.19 or later?

2. Were there any flanges present in the model?

3. Were there any flanges inserted in the model as a pair for a Valve or Flexible Joint using the ‘insert flanges on both ends’ option?

A ‘No’ to any of the above criteria means that this defect does not affect this model’s. No further consideration for this model is necessary.

Solution:

‘Insert flanges at both ends’ option for Insert Valve or Flexible Joint dialogs should be updated to create individual flange data records. Program should also automatically correct models from previous version on opening in the latest version.

Additionally, to assist in the screening of the models created in previous program versions for any potential impact by this defect, the program shall automatically examine the model database after opening the model and generate a report (model name + "_10166.TXT") listing the affected flanges.

Avoidance:

Remove all flanges that are present as a pair around Valve and Flexible Joints and were added using 'insert flange at both ends' option. Add these flanges again using insert > flange. Do not use 'insert flange at both ends' option while inserting any new Valve or Flexible Joints.

OR

Perform NTL round trip to re-create unique flange analysis records.
