    Compressed Gas Cylinder "C-10" connection

    I have a coworker who has spent the better part of a day beating his head against the wall on this one: Does anyone know of any specification, industry or otherwise, for a C-10 gas cylinder connector? We have a small compressed gas regulator. The regulator inlet is configured to connect to a...

    Turnbuckle, but for compression (i.e. clevis-ended jack screw)

    Tmoose: There are some other column buckling calculators around that will let you go to a smaller diameter, like this one: Link I am pretty certain that a 3/4" dia, 30" long pinned end column won't buckle under a 1000 lb load (I did use the calculator to double check). I am more concerned...

    Turnbuckle, but for compression (i.e. clevis-ended jack screw)

    The size I'm looking for would be around 30" long and have 3/4" dia pins in the end clevises. It would be rated for at least 1000 lbs of compression load.

    Turnbuckle, but for compression (i.e. clevis-ended jack screw)

    Nice. Those aren't the size I need but maybe I'll be able to find additional sizes somewhere else.

    Turnbuckle, but for compression (i.e. clevis-ended jack screw)

    I'm working on replacing a 4" ball valve in a run of horizontal pipe. All structure that could be used to attach supports for the weight of the valve is below the valve. The engineer who originally designed support for the valve used 2 generic McMaster-Carr turnbuckles from the to support the...

    Explain high stress spot in bolt joint with femap/NX Nastran

    Are you putting a preload on the bolt or just using the RBE2 to rigidly connect the 2 parts? If you're not using it for preload, is that really the best way, or should you define a bolt connection region? I am horribly inexperienced at Femap (just look at my other threads and you'll see), so...

    Way to suppress elements to for analysis?

    Dumb Femap question of the week: I'm working on my analysis of a valve in a length of piping. I need to analyze two cases. In the first case, the valve is supported by hangers. In the second case the valve is supported by the pipe. I'd like to keep both results sets in the same file. So, is...

    Vertical loads on horizontal cylinder solids

    Sounds like a good idea. I'll give it a shot.

    Vertical loads on horizontal cylinder solids

    Anybody know a best practice technique for applying point loads (simulating component weights) to a long horizontal cylinder? In my specific scenario, I have a large valve on a run of horizontal piping. For the analysis, I would like to just model the pipe and then apply a load to simulate the...

    Setting base point for lines "at distance"

    Oops, only one image per post I guess. Here is the first image.http://files.engineering.com/getfile.aspx?folder=cc9293d7-8515-4607-ac63-c7546654ea95&file=Capture1.JPG

    Setting base point for lines "at distance"

    I am so bad at Femap... I'm trying to draw a straight line beginning from the upper left point shown in the first image I posted. For the first point of the line, I use the "on point" method to select it. For the second point, I'm trying to use the "at distance" method since all I know is a...

    Constraints on mirrored mesh elements

    I think that did it. Thanks for the help. I was concerned that since my geometry is made up of multiple solids, and since the mesh is one big mesh covering more area than any single solid, the association would do something screwy. It seems that Femap programmers have come through for once...

    Constraints on mirrored mesh elements

    I'm working on 3D meshing a semi complex solid. I decided to make it easier on myself by cutting the solid down the line of symmetry, meshing the remaining half, and then mirroring (or is it called reflecting?) the mesh before I apply loads. I wanted to mirror the mesh because the loading is...

    Coil of tube / hose in XpressRoute

    Hi, Wondering if there is a way to create a coil of tube (imagine a coiled up garden hose) using xpressroute? I know that I could probably create the hose I need without using xpressroute, but just wondering if there is a more convenient way.

    Quick Disconnect Coupling Preferred Direction

    I use a lot of self sealing quick disconnects (Hansen brand mostly). One of my coworkers says that there is a preferred direction of flow through these couplings (i.e. female to male flow is better than male to female). I have never heard of this and cant find any guidance to support the...

    Formula in a Draft Background Template

    Unfortunately, it is standard for the Navy. 1) Even more unfortunately, the Navy won't change 50+ years of drawing border convention for anything short of an act of God. 2) Already do it this way. Some of our drawings are 30+ sheets. Typing those little numbers gets incredibly mind numbing...
