    Where to find models of branch connections?

    Hi all, I need to locate 3D models of branch connections (weldolets, sockolets and threadolets). I can find a few in a few sizes on McMaster-Carr's website, but I need a more complete library of these fittings. Does anyone know where I can find these? Thanks!!

    JIS 10K flanges

    Hi. I just received a request from a customer for my company to us JIS 10K flanges on their order. I'm not familiar with this flange spec. I know it is a Japanese spec, and the 10K refers to the pressure rating (at least I think). Could someone point me to an online table, offer a reference...

    Wedge Meter Tap Locations

    Hi all, I just started with a company that makes differential pressure flowmeters three months ago. I was hired because the company being consolidated back to corporate headquarters but none of the engineers were relocating. I forced as much information into my head as possible while the...

    Estimate Weld Cost

    Hi all. I am working on putting together a pricing program for our sales department that would allow them to enter in the dimensional parameters for venturis that we sell and obtain an estimate of our cost to manufacture. Dimensionally, it was easy to compute the weight of the unit, but when...

    P vs V of water

    The gauge is held at 70°F. My main problem is trying to justify to the customer why the gauge loses about 150 psig over the course of an hour or so. It must be the relaxation of the glass, allowing a larger volume. Like I said, a helium (I mis-spoke up above) leak test shows that the gauge is...

    P vs V of water

    Thanks Guidoo! I'll give it a shot and let you know how it worked out! Much appreciated!!

    P vs V of water

    My company makes liquid level gauges (my area being boiler trim). I am working on calcs for a gauge with a valve at each end. The gauge is pressurized to hydrostatic test pressure (at 70°F) and the valves are closed. Over the course of an hour the gauge loses about 150 psig of pressure...

    B31.1 102.4.5 Required Wall Thickness

    I will most certainly try it that way, cb4, thanks for your input. I'll post an update as soon as I can so that maybe others may benefit as well. Thanks again.

    B31.1 102.4.5 Required Wall Thickness

    cb4, Just to clarify, I am using a working pressure of 1500 psig. Given this pressure, I have a safety factor greater than 1.00 at the nominal wall thickness minus 12.5%, so I have plenty of wall thickness to start with. What I want to determine is my tightest bend radius that I can make with...

    B31.1 102.4.5 Required Wall Thickness

    Hi all. My company makes liquid level gages for boiler trim applications. I am working on pipe bends that join two gage sections together. Our current product (designed WAY before my time)has the radius of the bend at 1 5/8" (NPS 3/4 Sch. 160 SA-106 Gr. B pipe)which, according to our...

    Quick Way to Change Background Color

    I believe smcadman is correct. I have an AutoLisp programming book here, and VL, VLAX is not mentioned anywhere. Does anyone know how to do this without using VL-VLAX?

    Quick Way to Change Background Color

    CarlB, I tried copying and pasting the code into Notepad. I saved it as a .lsp file and loaded it into autocad. It loads it, but I get an error: Command: _appload Loading C:\colorchange2.lsp ... Error: null function*Cancel* Any suggestions?

    Quick Way to Change Background Color

    I am running AutoCAD 14.01 and need a way to quickly change my background color from black to white, and back to black again (without going through all the dialog boxes). Is there a way to change the status of a system variable to edit-able if it is read only (ie: CurrentProfile)? Is there a...

    Missing System Variable

    Estassoc, I have discovered that there is a difference in my version of Acad and everyone else's here. Don't know how it happened, but I am running 14.0 and they are at 14.01. Hmmm...interesting, since everyone's was meant to be installed from the same version. Thanks for calling my attention...

    Missing System Variable

    I am working on automating some tasks in Autocad 14. My problem is that I am missing a system variable called CurrentProfile. I have looked on several other machines at my company, all of which are running the same version of acad, and all of them list that system variable with the appropriate...

    Autocad Backup Files

    We work with AutoCAD 14 at my company (although I would like to upgrade to something at least within the last decade!). It is our company policy not to create backup files simply for space sake on our server, so each computer is set to not create backup files...

    Non-axially loaded plate with holes

    I am working on a design for vertically conductivity probes for boiler applications. Basically, I have an endcap for a pipe and I need to drill and tap holes in the end of it to allow the probes to be threaded in. I need to perform calculations to determine how many holes I can put in the end...

    Marking a particular data point in Excel

    Thanks IRstuff, worked great. I didn't realize you could click on a single point, whenever I tried, it would select the entire line.
