Bending Springs or Device for Aluminium Security Conduit

[SecJohn]

Hi

 

Am after some way of putting up to 45 degree bends in my aluminium conduit.  I am in the UK, the conduit measures around 13mm external and about 12mm internal - standards stuff available form ADI.  I use the 90degree and couplers already.  When I ask they say computer says no, to 45degree bends.

 

I tried micro bore plumbing pipe benders but the formers were not Goldy Locks, not quite right; that resulted in the pipe kinking or not fitting in the former.

 

Or maybe you know of a 45degree manufactured bend available?

 

Cheers

I dont think you can bend alli tubing much the only bends I can find are these https://www.securitywarehouse.co.uk/catalog/cctv-c-1/cctv-ancillaries-c-1_3/secware-aluminium-tubing-12mm-single-elbow-p-6071.html

 

45 degrees is a bit of a strange angle for running alli tubing though its a bit tight squeezing/pulling a cable through it too?

ali tube is 12.7mm aka 1/2 inch

 

you need a 1/2 inch spring, however it don't bend very well as it right cheap & nasty shite compared to what it used to be....

 

So I doubt your going get 45°

It's not the right type of aluminium for bending clean.

Not sure why I would ever need 45 but anything complicated I'd probably consider 20mm.

why  45° ?

[james.wilson]

I used to use a bending spring years ago but it won't work on it now as the walls are too thin

I have manufactured 90degree bends, i need 45 to set around some stuff, might get away with less thouh.

Okay so gave it a try and the spring is a good fit, i cannot get to 45 but i can get to 25 / 30 before it kinks or in one case snaps.  I will give it a go for real when i am next on site.

 

Will ping some pics on this thread if it is still open.

 

Thanks again all, appreciate it.
