How I Start A Vessel in PV Elite

Okay, so here’s the deal. When I first got my copy of PV Elite from COADE, and started learning, I had designers disease. I wanted something ON SCREEN right away. Had to see what the picture looked like, with no regard to setting anything up. Well, that was fun, I had my picture, but then I had to set things up, a little after the fact…

So, I started to work on that, and came up with a few things that I do either before I start the design, or maybe a little ways into the design that help things out.

Pick your Code
Okay, so first off, before you get crazy clicking on components, make sure that you have the right code selected. This isn’t a HUGE deal, but it’s nice to start out using Div 2 if you are doing a Div 2 vessel.

Select your Units
This one get’s me every time, and I don’t know why. PV Elite has several pre-defined unit styles, USE THEM. I get people calling me that they can’t calculate a 2″ straight flange on a vessel because it’s asking for length in feet, CHANGE YOUR UNITS! It’s not tricky, but people still miss it.

Design Constraints
This is a tab at the bottom, and should be one of your FIRST stops if not your first. This is VITAL information that needs to be reviewed and setup. You can pre-select certain values, for instance the Pressures and Temp’s right here, so that as you are putting the right info in, more on this in a minute. This is also where you are going to set your datum line, or in Kyle’s vocab, the strike line. Vessels don’t get built by measuring off the ground, quit designing them that way.

First Component
There is some debate, at least with one of my clients about this. I’m going to talk for just a second about this being a vertical vessel. Nothing fancy, just a straight up, 2 heads, a shell, and a skirt kind of vessel. He has always designed the vessel, then added the skirt, well, so be it. Your first component is whatever you want. PV Elite will let you insert components after the fact, really. It’s called the insert button. Great name for it. Build your vessel, then come back, and insert in what you need.

Fill In Some Data
Once you’ve put your first component, take the time to fill out a few things. The first, and biggest being, THE NAME! Name your components, this isn’t vital, but it sure makes life easier when you are reading over your reports. Next up, fill in the sizes and materials. PV Elite populates up. Meaning that the information you provide in the first setup, will be directly pushed to the next component you place. Taking a few seconds to set the information on the first component will save you lots of time when you start having to change them ALL! I tend to treat that first component like I was running CodeCalc. Take the time to set it up right, and you will save yourself a few minutes in the long run.

This is pretty much the start of my vessel, from here, it get’s fun. You actually start BUILDING the thing.

Hope this gives you a little food for thought, and take a few extra minutes to explore the software, and find the ways for you to get faster and more efficient.

Quick Material Selection for PV Elite

Short one today, but this is a nifty little trick in PV Elite that I thought I would share.

I was doing a tech day for a client a few days ago, and they asked me to mid-design switch material on a skirt. Not a big deal, honestly, I had forgot to set the right material from the start. There is a quick way to search for a material at the component level. Go to your material line item in the input panel, and type in PART of the material you want to use and hit enter. This will throw up a warning that the material you typed is incorrect, unless of course you typed out the entire thing. For instance, if I wanted to use SA-106 GR B as my material, I could just type 106 and hit enter. After you click ok on the dialog box, the “wildcard” searched materials will come up. Pick the one you want from the list. This will open the materials property dialog to show you the info on that material. You can either select that material, or hit back to go back to your search. If you hit select, then you will get the variables that you can modify, as well as calling the material out to be normalized or not. Click OK and you now have reset the material for the component.

Not an earth shattering tip, but a nice feature to grab the correct material quickly.

List Dialog in PV Elite

I’m going to break away from my normal CADWorx talk for a minute, and talk about another program that COADE makes called PV Elite. For those of your not sure what this is, it’s an ASME Code based pressure vessel design and analysis software. It works GREAT with CADWorx Equipment and Plant Pro. I highly recomend you take a look at it, or shoot me an email, and I would be happy to talk to you about it.

The feaute of PV Elite that I’m going to talk about today is the list box. This is one that stays hidden in plain sight.

I was recently in Arkansas for the Arkansas Society of Professional Engineers (ASPE) and their Winter Meeting. While I was at the booth, a PV Elite user, who was on vacation and staying at the hotel, came by and started asking me questions about the software. Some of what was bothering him was the inability to rapidly do “just like” items. Enter, the list box.

This box is a spreadsheet style dialog box that has an icon on the Auxiliary toolbar, or can be reached from the dropdown: Input>Display the List Box.

Here’s what the screen looks like:

Notice the tabs across the bottom of the input area. Nozzles, Weights, Packing, Force/Moments/ Rings, and the list goes on. Anything that you have to use a lot of, you can quickly duplicate right here. In addition, if your report says that something needs to be modified, a ring size for instance, you can open this dialog and change it here, where the data is a little easier to support.

Take a few minutes on your next design and look over the List Box, I think you’ll be happy with what you find.

As always, comments are welcome, and if you have any questions, please let me know.
