What do you need to bend and what are you making?
Could be easier to get it done by a fabricator with experience.

Hopefully not teaching you to suck eggs - but this comes up occasionally.
pipe and tube are different things. Pipe benders don't bend tube they tend to kink it.
Roll bars are tube.

Are you referring to the difference between welded pipe, which has a seam of weld down the length and CDS, being drawn seamless pipe and generally
more expensive, but stronger?

[im no expert - i just got this from reading on here]
pipe and tube differ by how they're measured. pipe is measured by its ID and tube its OD hence the former for one won't work on the other
without kinking due to the pipe / tube not being fully supported whilst being bent.

I'd go see Martin Keenan (MK Engineering, not sports cars) in Bawtry.
I presume he still has tube bending tackle, though from the website (mkengineering.co.uk), he's scaled back his operation.

My roll bar is made from pipe and I bent it using a pipe bender.
It's from 1.5" Nominal Bore, Schedule 10, 316L.
( That's about 48mm o.d. with a 3mm wall. )
I much prefer to think of it as the high level brake light mounting bracket though.
For road use (IMHO) I think that I'm far more likely to be rear ended than roll the car over.

Interesting and I would agree that in normal road use a collision and side/front/rear impact are more likely than a roll. Rear end impact risks the
fuel tank and side impact doesn't have much protection to the people in the car. Frontal impact also IMHO risks the occupants legs as the car
is likely to deform a fair bit. All that said, I don't see that most cages offer much additional front/rear protection although I have seen
some with side impact bars fitted, which may help in side impacts. The issue is IMHO that most cages are an addition to the car and not a structural
part of the chassis itself.

The accident I fear the most is the side impact. 
When out driving the Suttol every junction I pass or pull out of seems to have a vehicle menacingly positioned ready
to imbed itself in my right ear. The bonnet edge seems just the wrong height.
Can you get airbags that explode out of the side arms of your sunglasses ?
