Can you bend 4.5" AL .125" wall pipe

[bigsub]

Do you guys know anyone who can bend 4.5" aluminum .125wall pipe? And don't say muffler shop unless you know a specific one, i've called em all. I don't need a full 90 but i need a big radius and about 30 degrees. I need it to come out smooth. Its a short peice should I go get a tourch and try that? Maybe I can bend it over by propane tank while i'm heating it.

[sceep]

there is no such thing as 4.5 x .125 wall PIPE!




edit: BAAHAHAHAH... i didnt even finish reading your post until now.

please.. please... go fire up your torch, and use it right near your propane tank trying to bend that.

[bignissan]

yes...go bend it over a PROPANE tank while you heat it.

Hey Sceep can you explain your little personal picture icon to me i don't get it...... You guys are pathetic. I really didn't think it was necissary to include the little explosion icon in there to idicate my sarcasim but i forgot you read these too. And excuse the heck out of me. Tubing, pipe you know what i was talking about. Its round with a hole in the middle. If you don't have any good advice STFU

Any real advice?

uhm.. no actually we have NO FAWKING CLUE what you are talking about. theres no such thing as 4.5 x .125 wall PIPE.

Seeing how there is no such thing are we just supposed to assume that you have a custom 1 off die that is extruding the tube just for you and you want to bend it? or are we supposed to assume that you are in actuallity useing TUBE and possibly recomend useing the wrong type of bender, thus fucking up your expensive ass round stuff with a hole in it.

the answer to your question (Can you bend 4.5" AL .125" wall pipe?) is yes.

yes you can.

how? no fawkin idea.

fill it with sand pack it tight and weld the ends shut. then you can heat it and bend it around something without kinking it. never been over 3 inch this way but it should work

Sorry to say but they do make 4.5"x.125 wall pipe
you can get stainless steel from 1/4"-36"OD with a wall thickness up to 1.500" thick. http://www.fedsteel.com/p-stainlessPipeAndTube.html

And they do make benders that can bend that size of pipe and heres a link to a pic to show some of the size benders that are out there. http://www.bendco.com/Bendco's%20B%2036%20induction%20bender.JPG .

and here's a link to some aluminum pipe dimensions http://www.globaltecheng.com/alupipe.htm .

Ok let me clarify. Thanks for the help sasedyota. I know that there is a difference between pipe and tube. I'm not sure what the differance is or why there is a difference or what is what(could some one help here?...i don't know everything) But if Sceep would read more carefully before his last post I said I didn't know whether it was pipe or tube. So apparently what i have is aluminum tube. But it definitely measures 4.5 with a .125wall. And its readily available.

So any other ideas?

I like the sand idea, kind of a pain. I just wanna make sure there are no other precautionary measures. Should i leave a little hole in the end to relieve pressure or use a certain type of sand(very dry i guess) I've had a couple things blow up on me when they are buried in the sand and its not a fun thing.

[papee]

just how short is it?

[indysand]

Might be easier to just go here and buy a piece of prebent tubing. Not .125 wall though. May I ask what you are using it for? Cold air intake perhaps?

Its 36". Hey thanks for that link, that rules. If i don't use it here i will definitely later. I'm using it for a buddies spare tire carrier and part of my roofrack. Also gonna use it for exhaust(i got alot for free)

[papee]

It sounds a little short to get in a bender. It may fit when straight but once you start the bend it may be to short for the bender.

[bigsub]

I can cut it afterwards. What kind of shop or who has tools to bend it?

4.5 is pretty big, I doubt any automotive shops would have that kind of bender. Not many of us use anything much over 2.5in tube, so you may be on your own. Start calling industrial places, like shops that do exhaust for big rigs, industrial plumbing places, large iron workers or maybe some place that makes those big signs that go over highways (I've noticed some bends in them driving around, I always wonder what kind of bender does that, some of em look as big as 24in).

[sceep]

I'd start callin deisel exhaust shops.

Pipe = measured from inside out

Tubing = measured from the outside in.

I hope this helps.

You mean one is measured in OD and one in ID? Theres gotta be more differences? Thanks.

Nope. They're both measured based on o.d.

All 2" tube is 2" od and all 2" pipe is 2 3/8" od, regardless of wall thickness or id.

Why in the world would someone measure "inside out"?

[bigjeepguy]

pipe is "technically" meant for transport (ie steam or fuel) Tube is "technically" meant for structural usage. Search, this has been hashed to DEATH

[LandCroozer]

You're using aluminum on exhaust? Why does this sound like a bad idea? And 4.5" is huge.. I'm guessing you have a very large, very cool running engine.

Make sure your sand is dryer than sceeps vanay-nay sand before doing this or

:edit: I see that you have already adressed this bigsub, good job mang...actually using your brain.

And jesus, are we SERIOUSLY bringing up pipe/tube again!?! And are this many of you STILL clueless asshats on the subject? Pipe =nominal ID, Tube =OD. There are many differences including tensile strength weight etc etc but who teh fawk cares, he is wanting to bend some AL tube.

Bigsub, you say that you are getting a whole lot for cheap...just go ahead and make a jig, heat it, and bend. You could have already tried it and reported back as to weather it worked or not...

I think you mean Pipe =nominal OD, Tube =OD

I know, I've just been putting off buying a tourch and bottles. bling bling. Thanks for all your help guys. Oh and the exhaust is for a desiel

[fj40charles]

Why not just run 4 or 5" exhaust. Plenty of exhausts available for diesels. Unless you you're pushing 400+HP at the rear wheels, I don't see a need to larger than a 4" exhaust. Most turbo exhaust housing are smaller than 4"

[bigsub]

Exhaust was just a side thought. I haven't done the research to see if it will work. I figured it wouldn't be to big for a 8.3 cummins
