In this video, learn why project validation is an important function in the P&ID program, helping you make sure your P&ID is complete.
- [Instructor] Let's move ahead with chapter 12, and take a look at some of the project tools that we have available. We'll start by navigating to our exercise files, desktop, exercise files, chapter 12 project tools. We'll open our project XML. Let's take a look at our drawings, and these are the drawings that we'll be using for this exercise. So one of the advantages of using the Smart P&ID program, is that we have the ability to see whether or not our P&ID is complete, by running a check on the database. Before we sign off on our drawing, we have to use the validation tool to check for any components that are not connected, not terminated, not tagged and annotated.
I'll go through the steps with you now. Let's open drawing 1201. Now at first glance, when we look at this drawing, everything looks to be fine, and everything looks in place, but I'm going to show you how to make a check using the validation tool. If you want to look up here, we have two tools available, we have the drawing checker and the validation. You'll notice that when you open a drawing, the drawing checker runs automatically, and you can do this at any time through your drawing. It runs very quickly, and you won't really see much happening, it's just a quick flash, but you'll know that it's complete.
To run validation, what we can do is we can come down to our project, we have the option to run a validation on the project, by right clicking on the project and validate, which can take a long time. If you have a lot of drawings, a lot of information, it will run through everything in your project. So for this exercise, I'm just going to go through this one particular drawing. So to do this, I'm going to click on the drawing I want to validate. Right click, and then come down to about 2/3 of the way down, and you'll see the validate tool here.
I'm going to quickly run this validation, and you'll see it run through a number of checks. I'm going to close Project Manager down just so we can see a little better, and open this up. Now here's all the issues that we find with the drawing, so it's not as complete as we thought. So let's take a look at, start at the top and look at some of these issues. Non terminating lines, we can't have non terminating lines. They all have to start somewhere and end somewhere. So what we can do, is we can double click on the first line, and it's going to take me right to that point without the connection.
Now if we zoom in really close on this, you'll see that that's not, in fact, touching the nozzle. You can tell also because it has the cross grip, rather than the circular grip. So I'm going to go ahead and take that, make that connection, and you'll see that's turned to a round connecting point grip. We can go ahead and correct all the rest, zoom right in again here, and you'll see we have the cross grip. Let's change that til we get the round connector, and the last one here, we'll just go ahead and do the same thing.
So also we have unlabeled electrical signal lines. Now, in this project we've opted not to label the instrumentation lines, so we can go ahead and just take this right click it, and we can ignore that. We don't want this to come up every single time since it's already approved that we don't have to name them. Notice that just jump down into the area that's actually laid out for ignored items. So we can still see they're there. If this rule changes we can go back and then we can unignore these one, and tag them, but for now, they're out of the way, and we don't have to look at them all the time.
So let's take a look at spec mismatches, double click on that, and let's take a look at what's wrong with this valve. When we zoom out, we can see that this line is a CS300 line. Let's take a look at the valve properties to see what's happened here. And when you scroll down for the spec, you'll see that this little black outline here is showing that the spec has been overwritten. We can come back here and see that it's been changed to 150 pound line. To move this back to acquisition mode, we just highlight here, and again let's take a look.
And now that size has been corrected back to the CS300, it's now pulling that value from the line again. Unresolved off page connectors, this just means they haven't been connected, and these are absolutely fine. I wouldn't move these to the ignore section, because before the end of the project these all have to be connected. It'll flag us for flow direction conflicts. So let's take a look, we have HA-149, and in fact you can see we have a line, and the flow is running from right to left. The check file's showing the opposite flow, it's going the wrong direction.
So we can come in, and we can just go ahead and flip that. And it's now following the correct flow of the line. Unconnected components, this is often when there's connections made that maybe a nozzle that's not been connected to. We have instrumentation, the instrumentation is there, but the loop hasn't been designed, we don't know where the signal's coming from, so this is information that all has to be filled in as we go through. So let's just run a refresh again. I'm going to take it from the 1201 P&ID, I'm going to refresh this. And you'll notice that that list has gotten considerably smaller.
All the items that we fixed have now been corrected. So when you're working in a congested drawing, it's not always easy to see the items that have been missed. By automating this procedure with the help of the database, we can very quickly verify work that would otherwise take many hours to check manually.
