Tube Diameter Sizing

Tube Diameter Sizing

Tube Diameter Sizing

(OP)
I would like to be able to figure out the stresses put on the walls of the tube when I put it through the sizing operation.    What I am trying to figure out is how much can I increase the radius of a 4" x .065 tube until the tube fails.  

Any help is greatly appreciated.  

Thank you

RE: Tube Diameter Sizing

Sizing operation? Are you a tube manufacturer and you'd like to know how to increase the radius of a 4" diameter tube? Let me see... the radius of a 4" dia tube is 2", right? How do you intend to expand the pipe to split, hydraulic pressure or mechanical means? If it is a PVC tube, you only need a bit of heating and it will split in no time. It will be a bit more difficult if the tube is made of copper, but that's another story.
Hope it helps,
cheers,

RE: Tube Diameter Sizing

(OP)
The tube is a stainless steel 304 series tube with a .065" wall.  I am going to put it into a sizing machine, a tool with 6 segments that move out to expand the radius, But what I would like to do is figure out how far I can go based on the stresses put on the tube rather then doing it by trail and error.
