This is just a random image off Google but imagine this after 20-30 years of exposure to water and salt. You would have extensive paint failure and...
I am finding very little documentation when it comes to long term structural steel integrity. It seems to be an area with very little regulatory requirements. Codes specify that it is to be designed to a certain criteria with a suitable corrosion resistant coating. The coating applied will...
I have a 10' pipe with 2000 SCPM operating at 4-5 psig. I am trying to find the best option for an air flow meter. The air would be considered dusty which is why I am leaning towards a venturi style flow meter. Does anyone have any input on this and maybe a manufacture that deals with this...
rb1957,
The eye bolt passes through a hole drilled through the HSS tube which is fastened with a nut from the top. The eye-bolt is supporting a vertical load. I also don't believe this hole will have a significant stress concentration but I need to justify my assumption.
gurmeet2003,
No I have not checked it. I will see if I can track it down. Most books I have checked have stress concentration for rods and plates but no structural steel.
Does anyone have any reference material on how to determine the stress concentration of a hole in HSS tube. To give you an idea what I am working with, I have an HSS tube fixed at both ends with a 7 ton Eye bolt fastened through a hole in the center of the HSS tube.
Any information would be...
I believe you should look at an alternative way to handle your starch. You are loading 100, 90kg bags of starch per load which seem like a very strenuous task. You should see if your starch supplier can deliver by truckload. If they can, you could use bulk storage bins and have them filled...
Is the cracking occurring while it is cooling? Possible your brazing alloy is contracting at a rate which causes excess stress on top of the residual stress from punching. Regulating the cooling of your metals may prevent this.
The company I work for is currently looking at getting a FAE software package. Other location are currently using Algor. Does anyone know how the Inventor FAE compares to Algor? Can Inventor FAE analyze multiple parts or only 1 part at a time?
Thanks
The B.O.M. Management really depends on the type of fabrication/manufacturing your company does.
If you are a custom fabrication shop that rarely manufactures the same product, you could get away with tracking materials used per work order in an excel program.
If your company manufactures...
When you import the object in and select the material it will ask if you want to change the lead-ins and lead-outs. Make sure you say no or it will overide the dxf user defined lead-ins.
You just need to draw them on the same layer. Import the part without lead-ins to see which direction your internal and external cuts are going. It will automatically set your user drawn lead-ins & lead-outs in the default direction of the cutting head.
Depending on the complexity of the part, I use fillet with a radius of zero at the intersecting lines. It saves time not checking, but just makes sure they intersect. If the parts are very complex, it would still take a bit of time to do this.
Choco2000,
Just to add onto what mrMikee said, there are other things you need to consider when building bins & silos. One thing people don't look at is an anomaly called bridging. While the material is being emptied and an air pocket is created. This can put a large load on the sidewalls...
Ok I am also working on a program for changing all my layouts to windows default printer. I am getting an error at the end of the program. It does what I want but I am unable to get it to batch because of the error.
This is the lisp program I am working on.
