This is project is a pipe flange tool. Its for wrenching on flanges that are welded to pipe with NPT threads that go into various equipment. I came up with this design out of necessity. Previously I had been either using a large pipe wrench or a strap wrench. The pipe wrenches would always leave gouges in the soft aluminum pipe, to me that's unprofessional looking and not how I do work. Using a strap wrench was a pain to get good torque and was difficult to use in smaller places.
I Built this tool out of stainless I had laying around.. The handle is 1" square tubing 1/8" thick. The Pin's are made from 3/8" round bar.
Here is the tool. The two pins that are close together are 2" long. The one on the end is 3". I drilled holes through the square tubing that were pre-measured to the correct spacing to fit on the flanges. Then I tig welded the pins in place.
