12 t pipe bender

[oceanobsession]

Has anyone tried one of these type pipe benders are they any good
cheers ocean

For pipe, maybe. For tube they're said to be hopeless.

The Fraud Fiesta rear hub one (lots of links around) is probably a better bet, especially if you have access to a big lathe to make the formers.

do not ever put nice shiny thin walled stainless exhaust tubing in one, it gets f**ked properly (trust me )

Apparently it works better if the tube is filled with sand, there is a good video on youtube.

In general though, it will crush thin walled tube.

pipe bender

the comments are correct. I have one and any pipes that have a wall less than a couple of mm will crumple regardless of how gradually u try to bend them.

I have heard all sorts of techniques to stop crumpling but never tried them. If if had to bend thin walled pipe, I've taken it to a fabricators to do. So to be honest the bender was a bit of a waste of money!

They are good for bending scaffold pole. I used mine to make a security grille for the workshop window. Will have to take some photos of the exhaust pipes I threw into the scrap pile after my attempts to make a very light bend with one of those things.

The hydraulic ram has come in handy for other things, but mine isn't used as a bender any more.

Re 12t pipe bender

Hi me again. it would be stainless im thinking of bending 35mm ish diameter
are we saying that if i was to use 3mm tube this would bend clean

cheers ocean

No - it will kink it - I have used a pipe bender as an emergency measure for bending tube - both mild and stainless.
Won't work.
As malc says, great for bending heavy wall tube but thats about it.

it's a good job that i've seen this Thread i was about to goout and buy one of those

It's all in the name, A pipe bender for pipe, A tube bender for tube.

True, but does your car have an exhaust tube??

Like many things in life, people not entirely familiar with naming conventions etc. use what they are aware of

Vacuum cleaners are almost all known as hoovers
Vodka and Coke might come with Pepsi

For a lot of people the word tube and pipe would be interchangeable, until they have learned the difference.

Here's a question, at what point does a tube become a pipe

Cheers Woody.

I think I had read a few bits about it before but that link helped a lot!

No problem Sean I know the difference but still interchange the words!! Its just one of them things, As long as you know what you mean its OK

 

[malcolm]

Still as clear as mud to me. I had assumed the difference was in wall thickness, though it's suggested the difference is in the application and how the tube/pipe is specified?

So why do they call one thing a pipe bender and the other a tube bender? That must imply a wall thickness difference surely.

 

[hotrodder]

Tube dimensions are simple- OD and wall thickness
Pipe dimensions are more complicated- a 2" pipe doesn't measure up as 2" OD or ID, the actual dimensions vary depending on the pipe schedule

 

[snowcat]

The two terms are completely interchangeable, I use a couple of suppliers, and one lists BS1387 as tube, and one lists it as pipe, interestingly enough both have pipe clamps rather than tube clamps listed.......

you also wouldn't buy a rig to thread tube, but you would buy a pipe threader......

Pipe is a black art and only for plumbers to understand.

Tube is an engineering material and has logical parameters.

Fingers stated the obvious in the first response to this thread.

In Engineering you more then often need to accurately repeat a bend, try doing that with a pipe bender.

 

[madkayaker]

What about conduit?

 

[aero]

same as pipe, and sized the same.

Don't see you working out angles and making repeat bends on a hydraulic pipe bender as shown.

Here's my tube bender. It will bend up to 2" seamless tube by hand. By fcuk is it easier with the hyraulic kit you can buy for it though.

You can just see the degree pointer under the die. Good use for TIG rods!

hi, i find if you put the seam on the inside of the bend it will not wrinkle, although of course with multible bends this is'nt always feasible. you could make up a mandrel and two men (or ladies of course) can get around this problem.
