Tube Question for MVC...

[rroadkilll]

I have found a site to purchase pre-bent tube but don't know enough about it... is this a good deal?

JeepTubes.com

"1.75" ERW tube with .120 wall thickness."

Is this the same as DOM tube?

What is the difference?

DOM-Drawn Over Mandrel , the typical "DOM" is in fact welded, its actually a friction pressure lap weld, there is no type of filler used, the tube is drawn over a spinning mandrel by two other spinning mandrels, the extreme pressure and friction from the spinning roller welds the pipe. true seamless is done by actually shearing a hole thru solid billet material. technically this is also "DOM".

Electric Resistance Welded (ERW)
Cold formed, electric resistance welded tubing can be produced in round, square or rectangle shapes. ERW tube is produced by processing a flat rolled steel into strips which are cold-formed, welded and seam annealed or normalized (depending on the manufacturer). You can usually identify ERW tube by the blue strip down one side of the tube (which is the welded area). The ERW process can guarantee the weld to be as strong or stronger than the rest of the tube body. The origin from a flat strip results in a more concentric product than Cold Drawn Seamless (CDS). ERW can also be known as CREW (Cold Rolled Electric Welded).
Typical Applications:
Structural columns, beams, supports, heavy equipment frames with 58,000 PSI tensile
