Thread: Galv or black pipe for pipe cramps

My old work had some 6m gal pipe clamps and if they slipped you'd just give the release lever on the sliding jaw a tap down to make it really bite, then you could swing off the screw with a 2' bar without any problem.

I have galv pipe for some pipe clamps I made 18 months ago. I was planning on using black pipe, because that seemed to be the common thing, but Dad suggested galv would be better for rust. That seemed reasonable enough, so I went with galv.

- Galv hasn't rusted
- Galv hasn't slipped
- Galv is being chewed up by the sliding jaw. I don't know if the same happens with black pipe, but every now and then it peels up a piece large enough to prevent the sliding jaw from travelling over that section. I just have to fix it with a file to smooth it down, but it's also sharp as a burr. I'm not sure I know anything sharper than metal burrs, cuts me so easily

Thanks for the replies I think I will go with galv, I can also buy that pre threaded
