After examining the point information for A07, we note deflections exceeding our design criteria of 0.8 inches at point A07. In order to identify all points meeting these criteria, we will utilize

AutoPIPE's Result filter option.

Note By selecting the Filter option (or any other menu option), AutoPIPE automatically closes the displacement review windows.

1. Select Result > Filter Criteria > Displacement.

2. The Displacement Result Filter dialog is displayed as shown below.

3. By using the filter option, AutoPIPE will automatically highlight all points on the model that satisfy the filter condition for visual checking. Note that these points are added to the existing selection set. Furthermore, we can use this same filter condition to generate a report that contains only those points that meet the filter criteria. In this case, we wish to report only displacements greater than .8 inches. Enable the DX, DY, and DZ fields, then enter 0.8 {20} in the numeric field for each of the offsets as shown in the dialog above.

4. Press OK to close the dialog. The model appears as shown below. AutoPIPE automatically highlights the section of the model that satisfies the filter condition.

This section of the model is selected to indicate that it meets the filter criteria.

SELECTING COMBINATIONS

AutoPIPE provides an option to select which load cases and combinations will be included in an output report. The default is to include all load cases and combinations. You will now disable all load cases (not print) but the GR+T1 load combination in order to further minimize the output report. In effect, you will be generating a report that contains only those points that met the filter criteria specified for combination GR+T1.

1. Select Tools > Combinations and select the Non-Code Comb. tab.

2. The Combinations dialog displays as shown below. By default AutoPIPE enables all

combinations. You will now disable the GR load case (Print column) in order to isolate results only for the GT1 (i.e. GR+T1) load combination. Disable the following fields by clicking in the box adjacent to the field (ensure there is NOT a checkmark in the box next to the Gravity or Thermal fields):

3. Press OK to close the dialog.

4. The next step is to generate the output report. Select Result > Output Report.

5. The Batch Report dialog is displayed as shown in the following figure. Accept the default report file name, then make the following changes to the dialog; these changes allow you to produce a report which includes only those points which satisfy the displacement criteria defined

previously:

6. When the dialog appears as shown above, press OK to accept the values and close it. The output report is displayed in a separate window.

Hint Like any window, the output report can be re-sized, minimized, maximized, scrolled, printed, etc. Refer to your Windows’ documentation for more information on windows and their properties.

7. Note that only the points which met the user-specified filter criteria (exceed 0.8"

{20mm}deflection) for combination GT1 are reported. You will now close this window and return to our model. Select File > Exit to close the report window (you can also click the “X” in the upper-right corner of the window).

ROTATING EQUIPMENT COMPLIANCE

We will now perform a rotating equipment compliance check for an API 617 compressor attached to inlet point A00 and outlet point A14.

Note During this exercise AutoPIPE automatically uses the forces and moments at the user-specified points to perform the compliance check.

1. Select Tools > Rotating Equipment. The Rotating Equipment dialog is displayed.

2. AutoPIPE allows for multiple rotating equipments to be defined including pumps, compressors, turbines, etc. Specify unique equipment ID to identify this element. In the Equipment ID field, input compr1.

3. From the Type selection list, choose Compress for an API 617 compressor. After the type is selected, the Rotating Equipment dialog is filtered to provide additional fields related specifically to the equipment type (in this case, a compressor).

4. Press Tab to move to the Generate Report field. Keep this field enabled for reporting of this equipment in the generation of a compliance report.

ROTATING EQUIPMENT COMPLIANCE

5. Define the properties of the compressor by entering the following values in the appropriate fields:

Suction point: A00 Discharge point: A14 Shaft axis: Global X

Override Nozzle Coordinates: Unchecked

6. After the dialog appears as shown above, press OK to accept the values and close the dialog.

7. Now that the rotating equipment is defined, we can review the results of the equipment compliance check. Select Result > Output Report. When the Batch Report dialog appears, DISABLE the Apply Filter Criteria and Displacement options, and enable the Equipment option.

When the dialog appears as shown below, press OK to generate the report.

8. The Rotating Equipment report is displayed. This report displays the loads automatically extracted from the analysis and equations required by the API 617 compliance. AutoPIPE’s rotating

REVIEWING CODE STRESS RESULTS

As a last step we will interactively review the piping code stress results.

1. Select Result > Code Stresses.

2. The Code Stresses dialog is displayed as shown below. Press OK to accept the defaults.

3. The Stresses information window is displayed. AutoPIPE displays a color-coded display of the stress results by stress ratio. We see that calculated stress exceeds the allowable for the Amb to T1 combination by a ratio of 1.41 {1.53} at point A07 (branch side). Note that this occurs in our region of large displacement as shown earlier in our deflected shape.
