C-Clamps?? 2

[stech2006]

I am new at my current job and they just gave me something to study upon and maybe calculate. C-Clamps. I have never dealt with them. I am in the Leak Sealing Industry and basically we stop leaks. They are wanting to install several C-Clamps on an existing flange. If someone could please explain to me the use of these C-Clamps or where I could maybe find information that would be appreciated. Any calculation ideas as well. I am at a total lost with this. Usually with a flange leak we fabricat a clamp to stop the leak. Now they want C-Clamps and I do not know what to do.

Thanks.

Take a break and go the hardware store ask for a C-clamp. A little one that you can fit in your pocket will cost a couple of USD. Once you see it, you should be able to figure out how to use it on flanges, and how to analyze it. Go ahead, buy it; they're always handy to have lying around.

The C-clamps you really want for flanges are probably not in your local hardware store; they are bigger, typically forged not cast, heavy enough to break your foot if you drop them, and cost ~100USD. Now that you know what you're looking for, you should have no trouble finding them.

You also might want to check out either Wilton or Armstrong, both clamp mfrs, that have extensive lines and websites. Don't forget to check out "machinist's clamps" which are the kind without a twist handle, but instead have (typically) square drive heads, sometimes hex. These are ALOT more robust, both in cross section, bolt thickness, etc., etc.

For flanges, look at swing bolts (i.e.,

)
C-Clamps aren't too stable

To analyze the clamps look under Curved Beam analysis Budynas "applied Strength & Applied Stress Analysis" has a good section.

& Roark too:

You may want to look up G clamps too. If I recal correctly what the US calls C Clamps the UK calls G Clamps.

Also check "Vise grips" - They make locking pliers with "C" clamp shaped heads.

Don't be afraid to ask your boss or someone else at work for help either. Chances are someone else has done this and can probably point you in the correct direction a lot more quickly than we can.
