Yes this would be for my company's stock. Currently wooden bunks are used for standard storage. However as you have mentioned they get beat up over time. These steel ones are intended to be repeatedly used in staging so they will need to be more robust than wooden versions as they will...
I am trying to determine the max weight a steel coil bunk can handle (weight rating). It is to use HSS tubing for the frame and wedges (saddle). However I am struggling with how to correctly calculate it's capacity. Would I individually analyze one piece of HSS, take the side walls as buckling...
I did answer your questions.... let me elaborate:
- If the straps are pre-stressed, is the initial stress uniform all around or is it variable due to friction at each of the six corners of the bundle?
Manually strapped, I do not know if all uniform [human error], I would like to assume that it...
All bundles are handled in an automated setting using magnets. The bundles are strapped manually at another mill. My company is performing the automation not the production/manufacturing of the bundles, as to why we are trying to figure out max stacking, since more stacks = more space/capacity.
Just to point out that no shims will be intended to be used or required. This would increase cost and askew production. The point about adding the shims is not really at all dealing with the question at hand to figure out the tension the band is facing when being stacked/maximum force. The...
So to sum up, what method is correct? There has been a lot of input, and I thank you all for that!, but with what method would provide the accurate value?
From this:

So, for a stack of four bundles we have:
P = 19*4W = 76W
where W = unit weight of one pipe times the strap spacing
T =...
Here is the way I came up with the values.

Thank you for you help!!
I did it in a different way individualizing pipes, I will upload my calcs next week. My output was the same as BAretired's 1.155F.
I am trying to figure out the max force at which can be applied to the [bottom] bundle [ie the number of bundles capable of being stacked on top] for which is safe and that the bands/strapping can hold safely.
Here is the Min. Breaking Strength chart from Band-It...
@Robbiee I don't quite understand that...
As well could you just break it into quarters and just find individual forces on each individual pipe?
How would it be possible to make a spreadsheet of this and just type in say the bundle orientation [ie # of pipes] and it would give out a force...
Hello,
I am having a difficult time to try and figure out this problem for work.
I have steel piping bundled together in a hexagonal pattern that is strapped together [band-it strapping]. There have been instances of excess amounts of weight when these bundles are being stacked upon one...
