To clarify the topic at hand, DOM and seamless are NOT the same thing. Seamless tube is not produced from a plate of steel that is rolled and welded. Seamless is formed from molten steel in a round die, there is no weld.
DOM often comes with a seam visible, but not raised, as in a standard HREW application. DOM is HREW that has simply been run over a die to smooth the inside surface. It has the added benefit of normalizing the wall thickness and aligning the grain structure of the metal a bit better, yielding a bit more strength (on the order of 10 -20% depending on application).
John, seriously Ill back you on this one, I have seen and used much DOM, and at times you can faintly see the seam, but its more of the exception than the rule.

I know what you meant, and I know what crash is saying....we're talking what we can SEE.....not what is.....I've had runs of DOM with NO VISIBLE seam,and some were it is barely apparant....I can actually post pictures of DOM i have on hand that show extremes.....even the color is different.

actually max, I'm sure xjguy would rather just stay on his computer....QUOTE]
Who knows...
He may surprise us all with some "real world" hands-on experience. I heard he's working on a 4-point cage with some type of device on the top that will reduce the possibility of a roll-over by 85%.
I would like to see some DOM tubing with a seam, but it must be 1/2" dia. x 17.005' long on a rack four and 1/2" off the garage floor which has 3 coats of grey epoxy floor paint splattered with 6 1/2 different shades of pink florecent paint.
So use some pipe and get the heck on with it!
Next we can debate on how much preheating and postheating you need to do when changing your underwear!
Could someone tell me what "Go Jeeping" means???????????????????????????????
