It seems to me that it would turn sideways. Any thoughts appreciated! Thanks, Tyrel

The 3 roller style works like a ring roller except the rollers are tilted to the long axis so the pipe turns as it feeds through. All hydraulic and will straigthen 4 1/2" and 5" drill pipe. Tuboscope is one supplier up here.

The multiple roller style work like a wire straightener with round profile rollers. The pipe is allowed to turn and is forced straight by the squeeze pressure between the rollers. The ones I've seen at a distance look like the ones in the picture or a continous eavestrough machine. Farmers (especially Hutterites colonies) have built these with 1" pillow block bearings and scrap iron (like tractor and cultivator frames) to recycle coil tubing up here for years.

If you're a good scrounger, you could build one for 200-300$.

Sounds like you have 1.25 coiled tubing. Yes it will straigthen, but the straightener is different than a ring roller. Pipe straighteners I've seen come in two styles; 3 roller and 4 or more.The 3 roller style works like a ring roller except the rollers are tilted to the long axis so the pipe turns as it feeds through.
