[QUOTE="mxneagle, post: 940655, member: 21267"] I made a set of of 2" and 3 inch pipe. Simple really, just drill 3 evenly spaced holes and weld 3 nuts for screws to go thru the holes on a 1" long ring cut from the pipe. Then weld 3 long nuts (for joining threaded rod I believe) that go along the length of the pipe also evenly spaced but in between the first 3 nuts. Now all you need is a plate with 3 holes drilled in it for bolts to go thru it and into the second set of nut on the ring. The bolts go thru the ring and tighten just below the weld on the pipe header. Then tighten the plate down to the flange with a piece of rubber between the plate and the header to act as a seal. Make one setup for each end. pressure should be about 20lb but do not use compressed air, rather use nitrogen to help avoid an EXPLOSION. don't forget that the pressure in the pipe will rise dramatically (the ideal gas law states that P1*V1 = P2*V2 since V1 = V2 the pressure is directly related to the temperature of the gas inside the pipe. You should also put a blowoff valve in the small end plate. I've seen a pipe explode using this method and it sounded like a quarter stick of dynomite going off. fortunately the pipe just ripped wide open and nothing came off. If it did it would surely remove whatever part of your body it hit! I don't think a propane torch is hot enough and an acetylene torch usually will burn off the plating. [/QUOTE]
