Two Production Scenarios:
A) Insert a 5/8" OD Tube .049 Wall SS304 into a hole in a 5" SCH40 Pipe. Then weld on the outside of the pipe and tube.
B) Welding 5/8" OD Tube .049 Wall SS304 to another 5/8" OD...

Any good resources with images of a good roller expanded tube and quality errors for poorly expanded tube?
Options in Elliott Tool's info online? They provide a good formula and recommended wall...
