How To Bend Stainless Tubing

Stainless steel tubing can be tough to deal with, but there are several different techniques to simplify bending this tough material. It's possible to do it by hand, but if you have a professional machine for bending tubing, that may be a better option to pursue.

The Process

With the help of bending dies, a bending machine intended for steel tubing, and other methods, you might get the job done more quickly and more accurately than if you attempted it by hand.

The stainless tubing can be bent using a ram bender by securing it in place on both ends and ramming the tubing in the center. This method tends to damage the tubing, however.

Another method of bending stainless steel tubing is to use a mandrel bending machine, which is a flexible insert that fits into your tubing, bending it without allowing it to collapse internally.

A ring roll bender will allow you to create a circular shape with your stainless tubing, by forcing the tubing into a perfect circular shape without allowing the internal structure to be compromised.

Another method is the rotary draw bending machine which is capable of creating more ornamental bends without marring the finish on the outside of the tube or compromising the inside. A stationary die holds the tube into position and then the tube is bent into the desired position using a forming die.
