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...
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...
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...
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...
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...
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...
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.
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...
I'm working on modifying a draft background template. My company's draft template has a "map grid" type border on it, with A, B, C running up the sides, and numbers across the top. The numbers start as 1, 2, 3 on the first sheet, then progress (i.e. on sheet 2 the numbers are 4, 5, 6). The...
I had the ball and seats of a ball valve analyzed using X-Ray Fluorescence. They're supposed to be made of Ferralium Alloy 255 (UNS S32550) and treated by the "Nobleizing - B" process. What I found was that they all had much lower levels of Copper than they are supposed to.
ASTM A240 lists...
I recently inherited engineering responsibility for a poorly performing test assembly. The performance issues all result from a 4", 600#, Metal Seat, Floating Ball Valve that is intended to serve as a hydrostatic test boundary.
For background: I've attached a line diagram of my test assembly...
I am by no means an expert, or even generally competent in ST4, so forgive me if this is a silly question: I'm looking for a legend that defines the meaning of every icon in ST4. For example, when you're in Assembly mode and you've got a part that isn't fully constrained and those little...
Hello All,
I've recently started using SE ST4 and had a question about working in an assembly. I created some reference planes in a couple part files that I planned to use to help me assemble them later on. When I added the parts to the assembly, I realized that the only way I could view and...
I have to preface this question by saying (very embarrassed) that I am working in V19. I work for the US Navy. What does that tell you about our government?
Now, I before I got this job I did a fair amount of work in ProE, SolidWorks, and NX. Most of my work I've just done with a mouse, but...
Hi everybody.
I am working with a large (7000 gal) horizontal tank that has a single vent in the top. I am trying to solve the following problem:
Before opening the tank, conditions are STP with a mixture of hydrogen gas and air in the tank (say 50/50). I will then open the vent, which is a...
