Testing new duct and pipe types

Step-by-step guide

Set properties and routing preferences, then test the new duct and pipe types.

1. Start a new project using the template Mechanical – Default.rte.

To create a new duct type:

2. In the Project Browser, right-click the existing Standard pipe type and select Duplicate.

3. Rename it to “Low Temperature Hot Water”.
4. Right-click the new pipe type and select Type Properties.
5. In the Routing Preferences dialog box, click Edit.

6. Set the Pipe Segment to Carbon Steel Schedule 40.
7. Set the Minimum Size to 1/2".
8. Set the Maximum Size to 8".
9. Click Load Family to load the fittings to be used for the new standard.

10. In the Load Family dialog box, navigate to Pipe > Fittings > Malleable Iron > Class 150 > Threaded.

11. From the available selection of fittings, choose Cap, Coupling, Coupling Concentric Reducing, Cross, Elbow, and Tee.
12. Click Open.

13. Change each fitting type to the malleable fittings just loaded.
14. Set the Minimum Size for each fitting to 1/2" and the Maximum Size to 3".
15. Set the Maximum Size for the end cap to 8".

For pipes sizes larger than 3", a flanged connection will be used.

16. Click Load Family again.
17. Navigate to Pipe > Fittings > Gray Iron Flanges > Class 125.
18. Select the threaded flange.

19. Click Open.
20. In the Routing Preferences dialog box, click Load Family again.
21. Navigate to Pipe > Fittings > Gray Iron > Class 125 > Flanged.
22. Select Cross, Elbow, Reducer, and Tee.
23. Click Open.
24. Select the row containing the threaded malleable iron elbow.
25. Click Add row to add a second row for elbow fittings.

26. Repeat this step to add additional rows for Junction, Cross, and Transition.
27. For each of the new rows and the Flange row, assign the appropriate Gray Iron pipe fitting.
28. Set the Minimum Size for each of the new fittings to 3-1/2" and the Maximum Size to 8".

29. Click OK to close all dialog boxes.
30. Use the new pipe type to draw a run of pipe at 3" or less.
31. Draw a similar section at 3-1/2" or above.
32. From the Modify tab of the ribbon, use the Split Element tool to add a break in each pipe run.
33. Review the range of fittings used within the same pipe type created at different sizes.
