Learn how to model main pipes and become acquainted with two distinct pipe types used in a specific project. With clear instructions, this article guides you through extending pipes, adding fittings, and adjusting routing preferences for optimal project results.
Key Insights
- The article provides a step-by-step guide on extending main pipes in a project, ensuring the correct direction and placement for optimal functionality.
- It introduces two types of pipes - fire protection T's and fire protection outlets - and explains the different situations where each type is used.
- It also explains how to adjust routing preferences to include a preferred junction type and how to switch between a standard T and a reducing T based on pipe diameters.

In this video, we'll get into modeling some of our mains and also discuss the two pipe types we'll be working with on this project. So let's go to our level 1 piping plan. And if we zoom in here and click on this piece of pipe, this is a portion of our main that has currently been capped.
But we're going to extend it and continue, so let's drag over the cap and delete it. If we click on the pipe here, we can drag. Be careful not to come at an angle, but we'll just go straight down.
This dashed line lets you know you're going in the right direction. I'm holding my middle mouse button to shift as I go down, and we'll stop just about here near the wall. We'll worry about its exact location later on.
Now let's go back to that pipe. Right-click, draw pipe, and we'll go in this direction. Again, making sure the dashed lines are straight.
And we'll go all the way down until about right here and press escape. And let's pan back and see what happened. So this put in a 90-degree elbow, which is good, but we want to continue in the other direction, so we're going to need a T-fitting, so let's get rid of this.
And let's go to this pipe and click and drag. And we'll stop about right here. Okay, now this main, we can drag this into the center line of the pipe and let go.
And now we have our T-fitting. If we look at this piece of pipe and click on it, the properties of it are fire protection Ts. This is why we have a T-fitting put in here.
Now if I click on this, the current fitting is a reducing standard T, which we actually don't want. And the reason is because all of these pipe sizes are the same. They are all 2 1⁄2-inch diameter.
A reducing T we would use when at least one segment of pipe was a different pipe size. Now this has to do with our routing preferences. So what we can do is we can change it.
Let's click on this piece of pipe. And under the properties, let's click edit type. And we should see routing preferences and click edit.
Now we have our preferred junction type, which is a T, which is what we want. We go to the junctions. We have a threaded reducing T for pipe sizes 1⁄2-inch diameter to 1 1⁄4-inch.
And a reducing T from 1 1⁄2-inch to 6-inch. Let's change that. If we click on it, we can go down and select FPT standard.
Click OK. And OK. Now let's delete that T. And reconnect these two by dragging this until you see this target symbol.
And now that's one piece of pipe again. And we'll drag this into the center line of the pipe. And now if we click on that fitting, it's a standard T. This is what we want.
Now I mentioned there are two pipe types. We have fire protection T's and fire protection outlets. We use them in different situations.
And let's talk about the outlets right now. So again, let's go ahead and delete this. Reconnect this one.
We'll click on this piece of main. And let's change it to fire protection outlets. Now when we drag it into the main, we'll see what happens.
To the center line. Let go. And now our connection.
We have a welded outlet and a coupling connected to this piece of pipe. Depending on the situation, we'll use our outlets, which could either be for groove pipe or for threaded pipe. Or we can use our T's like we did previously.
So let's go back and set this to fire protection T's. We can just go back, go back, go back. And there we go.
