The Official Tube Bending Thread

Hello, my name is Shane and I work at Baileigh Industrial here in Wisconsin. We deal with the Hot Rod and Restoration crowd on a daily basis and would love to get involved on the board and help out in our area of expertise.

We have a whole team of metal fabrication experts here and we specialize in tube bending and odd applications.

So, I will start this tube bending thread. If you have any questions about roll cages, bending tube or pipe, application issues, what wall thickness will work or not, wall thickness vs. center line Radius or what material will bend. Pretty much anything related to tube bending......ask away.

Shane

I've always wondered when and why would you use pipe and when and why would you use tubing?

I've been doing this for a long time, so I have talked to allot of guys out there about their applications. Tubing is best used for roll cages, frames and chassis... etc.

Pipe is often used for hand rail, fencing, gates and fluid applications...etc

Believe it or not, I have had a couple guys call who were building Rock Crawlers out of Schedule 40 pipe. It's rare, but some guys are doing it.

Welcome to the forums, your expertise is more than welcome here. FWIW do not post any commercial web sites you are affiliated with, or push your business, that is not allowed.

Pipe is a vessel for carrying fluids. It is made to an INSIDE measurement and this measurement should remain consistent regardless of the outside measurement.

Tube is a structural member made to carry loads and is manufactured to the OUTSIDE measurement and a load rating which will remain consistent.

Technically speaking you should be using tube to build stuff with and pipe to carry the water/brake fluid etc. but that doesn't stop people interchanging uses without a problem if you know the limitations.

Welcome to the machine........

Just what are the limitations? Besides the measurement differences; is one superior or inferior to the other in terms of overall strength, bendability, or fab-ability? Is pipe made of a lesser grade of steel than tubing?

To be quite honest with you, I am not a metallurgist. So questions about grades of material and what they are made up of, I am probably not going to be too much help.

But I sure do know tube benders and tube bending applications. I also know that if I was in a roll over, I would want my cage to be made of tube and not schedule 40 pipe.

Your bend quality will depend on your wall thickness and how tight of a bend you are trying to achieve, in addition to what type of bender you have. Too tight of radius and too thin of wall on a rotary draw or rotary compression bender, you will get ripples, even tighter, and the tube will crush like a pop can. That is why exhaust bending is not very successful on a rotary draw bender. A mandrel bender is needed.

I would agree with Baileigh. If you want max strength per pound Tubing -- more specifically drawn-over-mandrel tubing -- is the best product.

You guys have alot of nice looking machinery. Is it manufactured here or overseas? The rdb 100 bender looks like it would be the perfect addition to any shop needing an economical manual bender. The ratchet wheel looks alot easier to use than the bar type ratchet that JD2 has. I also like the fact that it can bend on top of the frame, instead of between the frame. My Hossfeld can be set up to bend on top, and that makes a big difference in time spent bending tube to fit.

Later, mikey
