how to model a semi circular ring main with the following configuration?
(Top view of semi circular ring main, each circle represents a pipe connected perpendicular to the ring main piping)
In this example, the ring main will be created off to the side and then copied / pasted into position.
Step 1. At any location, insert an anchor
Step 2: The ring main will be on Laying on the X-Z plane, insert a temporary pipe of any length (ex, 3 feet) in the X=axis direction
Step 3: Start the Ring Main wizard
Enter the following:
a. Offset from point = A01 (current node point)
b. Ring orientation = 90 deg (see image at bottom of dialog to help with orientation, use 90 deg to lay ring on X-Z plane)
c. Create new segment = Enable checkbox (to make it easier to copy/paste later)
d. Radius = 203.5 (can be any value but in this example the semi circular ring radius = 16' 11.5")
e. DX = 203.5 (specify exact direction of radius)
f. Branch type = Run (enable check box),
g. Pipe Identifier = 12 ( select current pipe id for your model, in this example Pipe Id = 12 was used).
Press NEXT button
Step 4:
a. click on the word Custom Angles
b. Enter the angles as shown in the drawing above
c. Header length = 3 inches or 0.25 feet
Press Finish to insert the ring main.
Notes:
1. In this modeling approach, node points A00 - A01 - B01 were uses as construction aids and will now be removed.
2. Use Copy / Paste / Rotate / Move commands as needed to get ring main into the proper location / orientation.
3. Use Convert Run to Tee command as needed to model connection points or model runs to center of 3 inch header node points provided in step 4 above.
4. Yes, AutoPIPE could have automatically create all the vertical connected pipe, In step #3:
a. Update Branch type = Tee (enable check box),
b. Branch Tee Offset: DY = 1 ft
Using either approach, the user can continue modeling branch piping from header, or connect existing piping to ring main as required.
