To quote Gene, he said...
"Ain't no way I'm gonna bend my 3/4" pipes."
Remember pipe clamps can be made in any length. A 4' X 1/2" pipe clamp is unlikely to bow or bend. However go out to 8' or 10' and a 1/2" pipe clamp may bow even with moderate pressure. If it bows it racks the clamp pads and you get uneven pressure.

Bowing is one thing, bending is another.

Yes it is. I don't think I said to the contrary.

No, you merely changed the subject from bending to bowing.

All of my pipe clamps are using 1/2 galvanized conduit. I have never had one slip or bend. If you use his wipe the pipe down with something to remove the oil film on it the first time. Some of mine are going on 40 years old

I haven't bent 3/4" pipe either, but have (slightly bowed) 1/2" pipe. Years ago when clamping butcher block type of construction. Don't remember what brand (sears I think) of clamp. But I remember using a adjustable wrench to extend the handle of the clamp. And then I was surprised to see how much the pipe was bending. I also had some I-beam clamps (probably 50 years old) that had large levers on the screw to put extreme pressure on the clamp. They were awkward to use (used a bolt thru center holes for adjustment) and very heavy so I eventually got rid of them. I finally could afford nicer stuff. In fact, I'm still upgrading some of my older, not so good clamps with better stuff, and also plan on buying some of the new clamp designs (knuckle, etc). In the past I've tended to spend money on tools and barely gotten by with clamps.

Why was I always instructed to use black pipe for pipe clamps. For some reason galvanized was supposed to be bad. WHY???
In fact I didn't know that some folks used galvanized.

I do not 'know', but hazard a guess that the galvanizing is 'bumpy' and tends to be 'slick'. I have used it successfully though it is prone to slipping.
More recent galvanized pipe seems less bumpy.
