I can offer some information, but not much specific.

I usually purchase a fait amount of 6061-T6 in 1.5 and 2" with various 
wall thicknesses and it comes with color coding paint on thr ends.

Steel Tubing "usually" doesn't have a welded seam, while pipe "usually 
does.  Structural steel tubing has a seam and comes in both schedule 40 
and 80, like pipe.

If you find steel that is relatively smooth and no sean and standard 
wall thicknesses like 1/8, 3/16, or 1/4, it's probably DOM or Drawn Over 
Mandrel.

About the only way I know of to figure strength is "I believe, a 
durometer test for hardness

Sorry I can't be more specific, but there should be members far more 
knowledgeable than I on here and maybe one of them will step forward.
