bending muffer pipe

went to the muffler center picked up a piece pipe , run it through my mandrel bender , uhh !! ripples , heavy pipe thought it would work . now what ?

 

Pipe (tubing) wasn't heavy enough. Example....Hossfeld dies require minimum wall thicknesses for various tube diameters and bend radii.

 

Not sure what your trying to accomplish, but you might try welding a cap on one end, filling it with sand, welding on a cover for the other end and then try it in the bender.

 

The pipe I was bending .070 + thick , alway's something new to play with , something new to learn .

 

What diameter TUBE and what centerline radius were you trying to achieve ?

Muffler shops don't deal in pipe.

 

I just buy straight pipe and the mandrel bends I want then but weld them. Much easier. But since you have the bender...?

 

The how is he supposed to get a mandrel in it?

 

As ridiculous as it sounds I did this while bending up some 1 3/4 pipe on a cheesey HF bender, linked below, and it worked like a champ. Not sure if it will work for exhaust pipe or not. The easiest would be to do what rab71 said.

There is no such thing as 1 3/4" pipe.

 

Not sure what you mean by there is no 1 3/4" pipe............

the die i was useing 13/4 , everthing fit nice . i don't have a problem using heavier tubing , I'm going to bend the cages for my 26 T & my 33 ply. thought I'd make my own headers too . I like the idea of doing as much as I can for myself , just bought the bender so I'm just playing now .

 

What bender are you using? what is the wall thickness on the pipe? what radius are you bending? Lot's of variables.. Jason.

 

Sounds like a cheapo compression bender,not a mandrel bender.

Mandrel benders support the bend from the inside of the tube.

 

what you posted was a link to exhaust tubing.... TUBING! there is a difference between tube and pipe, if you can't tell the difference then you need to sit back and read and not interject your comments....

 

pipe is measured on the inside, pipe is used to move stuff on the inside like water, gas, poo, tubing is measured on the outside and is used as structural as in, roll bars, cloths racks, and exhaust is tubing even though exhaust goes through it, a mandrel bender has a solid or segmented suport that goes on the inside of the tube while its being bent, thin wall tube will wrinkle if its bent at to small a radius, without having a mandrel inside it as its being bent.

 

will if this works

 

wait a minute...are you using exhaust tube for roll cages?

 

Budd, I appreciate the clarification.

Zman, you obviously had the opportunity to provide the same type of clarification but you chose to be an ass.

To me it comes down to a simple question. Regardless if it is "tubing" or "pipe" would the concept I mention work.

Answer: Yes.

If you want to pick apart the semantics then go ahead. I am simply trying to provide a poster a simple way to resolve an issue. Obviously you have many posts and I, obviously, am listed as an FNG. Not sure that holds much water outside of the fact that you spend way too much time in front of your computer probably eating Cheeto's with an orange penis.

 

first off, you don't know what a mandrel bender is, second you don't know the difference between tubing and pipe. if you think that you should be giving advice based on something you did with your HF pipe kinker then go ahead, but you lack credibility not because you're a FNG but because you don't know what you are talking about.... get over it already

 

wow tuff room...orange penis and all!

 

just as long as nobody offers to lick it off...

 

Tried to post a pic . as you can see that worked too . I have a E-Z , bend mandrel bender , the muffler pipe is 1.750 AL anyway that is what's stamped on it .

 

I have a JD2 model and the dies for 1.75 TUBE show the minimum wall at .095 for a 5.5" die and a .083 wall for a 6.5" die. Either way yours is even thinner.

 

This is what you have???? This is not a mandrel bender.. I got this off the e-z bend website.These will be almost impossible to bend thin wall tubing on...you could pack with sand and weld the ends shut to bend it on this bender..... Jason

 

Nope , I have the 90 degree EZ tube bender . as i said the wall thickness was about .070 .

 

Ok...is this it????This isn't a mandrel bender either..That's why guys are being hard on you...You could pack and cap to bend thinwall on this bender also... Jason.

 

Here, ia a pic of his problem.. bender is in the background.....

 

i have looked at pics of that type of bender before and i think without to much trouble you make it into a mandrel bender, just a plug mandrel. that would get rid of the wrinkles. heres a pic of a segmented mandrel, a plug mandrel does not have the little dunuts on the end.

 

ok heres a site with some easy to understand examples of a mandrel bender. http://www.toolsforbending.com/mandrels.asp
