pipe clamp

[brownbagg]

i need a pipe clamp. no not a clamp made out of pipe but a clamp that will hold pipe, not as a 45 but something that wont slip off the round. like today i need to clamp an angle to a pipe to weld, but it kept slipping off

any ideas

friction - or - riser clamp

For just temporary use, couldn’t you use a worm drive “radiator” clamp?

Chain vise grips.

If you just want to hold it to align for welding, this is what I use. I got mine at Tractor Supply, but Northern Tool should have them.
