I need to adapt a 6" tube to 6" pipe. This is for a solar mount. The mount is supposed to sit on top of a 6" vertical pipe but the GC installed a 6" tube instead. Said he didn't know there was difference. Told me he installed the one that was 6". So any ideas?

Tubbing is round (EMT) 6" outside diameter. Pipe is about 6-11/16 inside diameter. Pipe is a cap that goes over the top. Has two bolts that secure it at 10 and 2 o'clock. But it's loose when the bolts are all the way in. And this is a mount for 4 solar panels. At the top of the cap are some flanges that a large aluminum beam goes thorough. This thing is a sail and needs to be very secure. I just though maybe someone had a sleeve idea I could use to fill the space between.

This is a picture of it. It's the part at the top of the pole.

They weld nuts on the pipe for the bolts. So just tapping the pipe must not be enough treads. There is a lot of stress on these in a 70 mph wind.
dealing with what I have at hand, I would, as J said, rip a piece of 1/4" x 6 " pipe down its length. Drill 4 x 1/2" holes around its circumference, wrap it around the top of the tubing, and then plug weld it in place. Then apply the pipe w/set screws.

What if you made the shims as suggested previously, then drill through both the pipe and the tubing on both sides and use a long piece of ready rod (5/8" or 3/4") at 2 places, 90 degrees out and I'd guess at least a foot apart? Long 1/4" bit and a hole saw would work.. That would definately snug everything up and stop it from wanting to spin in the wind.. Just a thought..
