No it won't.....
Pipe OD's and ID's are different than tubing....so that's the first challenge.
Schedule 40 pipe is as follows...size is based on ID, not OD.
Pipe size:
1/2" has 1/2" ID and .840" OD
3/4" has 3/4" ID and 1.050" OD
The welded seam would be the second challenge. Pounding DOM seamless tubing into bent bars will be enough of a challenge on it's own.
...and if you are going to go thru the aggravation of removing the cross bars, use cro-mo tubing.....yield strength of cro-mo is around 70,000 psi vs low carbon steel at 40,000 psi.
If you choose to use low carbon steel go up a couple of wall thicknesses.
Seamless Cro-Mo DOM tubing is readily available from McMaster-Carr
