Don't they sometimes call DOM "seamless"? Though it seems like I have heard of both DOM seamless and extruded seamless

I'm pretty sure DOM is just HREW thats went through a mandrel afterwards which cold rolls it making it stronger
I believe DOM is welded tube that has had a mandrel pulled though it. Karl is referring to seamless tube. There is an argument in the tube industry over which is stronger. It is generally accepted that seamless is stronger but but can be argued the other way. The seamless people say the welds on welded tube are a weak point. The welded people say the welded tube is stronger because of more consistent wall thickness as Karl explained above. The good stuff will not show a seam anyway. We keep both in stock at work. I use the welded unless specified otherwise. If either was crap we would have blown it up by now.
I take back my previous statement, DOM is HREW that is drawn through a mandrel. This thereby makes my theory of why DOM would be heavier a flaming pile of ****.....
I see no reason why DOM should weigh more than HREW.
DOM should not weigh more, but I promise, it is significantly stronger. A big enough difference that you can tell real quick what you are pulling on in a bender.
why dont we all just use square tube for our cages and frames like the square drive shaft kids?
You die! You die and go to hell!
I used both chromoly and dom for my new cage and other tubework. The chromoly is a little stronger and lighter with .095" wall thickness compared to the .120 dom. Regardless they're both strong, the main gain is in weight saving.
Ed Zachary - Cromo is for long haired pretty boys who....er wait. :flipoff2:
I was thinking about square tube cages the other day when I was looking at all the ROPS's on tractors. Then you could pin it and make it removeable!
i figured this can go here. is that square tube?
