As a sheet metal worker I personally would have made a segment pattern. It was still interesting to watch how people find a different techniques to end up with same results
After figuring out how you came up with the numbers for marking the pipe, I tried it today on a piece of 1" EMT conduit that I am using to build new exhaust pipes for my lawnmower. Excellent results!! Thanks...
I tried an idea some one show how to make a point with pip, and it work well by drawing it out on paper first then with a black marker on to the pip then cut off the pieces not needed tap it with a hammer to bend and weld it up. I have a 20 ton press that I bend pip in with no problems. It does get some wrinkles in the pip the tighter the bend though.
Thank you for posting this video it’s interesting. I’ve noticed that there are other comments posted here about how to bend tubing. I don’t remember anyone saying this is the only way to do this. This is just one way. As a bender of hydraulic tubing for a number of years, one must remember that the outside of the bend radius stretches the tubing and reduces the wall thickness.The inside of the bend radius compresses the tubing. This technique although not something that can be done quickly, illustrates how to make a bend radius for which there might not be radius blocks. One might note that with this technique, there is very little stretching of the outside radius and no compression on the inside radius. Additionally once this is welded, this is the radius you wanted and this is the radius you got. Any other technique may require additional work especially if you’re filling the tubing with sand and heating it. Way more to this than meets the eye.
True, but using pie cuts is simpler, or use a mandrel and bend the radius you want. All the abrupt edges inside are a nitemare for fluid and airflow. Take a look at hydroforming, pretty amazing how strong it is and the shapes that can be made with it.many car/truck frames are now done by hydroforming.
There is no suggestion in the title that this is the only way, and there is no suggestion that this is one way. The title just says “GI pipe bending without bender”. There is nothing to do with wall thicknesses and over stretching and anything else you’ve decided to add from your mastery of experience. So I was expecting something novel that might have expedited the process but by the time I reached the middle of the video I was already thinking that I should just buy a bender.
If you have a torch you can fill the pipe or sq tube with sand cap the ends I tack a piece on the ends heat it and bend, I have used this many times, you get no wrinkles, this from a long time welder
This is outstanding! It would appear that this method would scale up or down depending on the diameter of the pipe. Can someone confirm this? If so, one can simply remember three numbers 15, 21 and the diameter of the pipe rather than the whole process. It would be very helpful to know the diameter of the pipe he used.
Generally when people are displaying a technique like this, we see it used to create a 90 degree angle because typically that’s the angle we need. That pipe looked to only be roughly 80 degrees. This video does however get the point across but requires my own calculations to get the 90 degree angle I need.
To be fair if you think about it the cuts are done by hand, therefore not perfectly straight. So they don’t fit perfectly right. Thus not being able to bend all the way to perfect alignment.
Boa tarde! Amigo achei muito top e método de fazer uma curva em cano. Após uma na NET consegui encontrar este vídeo com estas dicas valiosas parabéns! Muito mesmo. Fique com Deus
Top mesmo , gostei da dica só não entendi o cálculo para o espaçamento 0 , 15mm , 36mm , 51mm , 72mm . . . Ficou entre 15mm e 21mm consecutivos o espaçamento. Muito bom mesmo daora ainda mais para tubo , pois é muito complexo de se trabalhar não é para qualquer um se não se perde.
He needs to remove a total of 75mm of material within the space of 160mm. He does this using 5 x 15mm cuts which works out to be ~21mm spacing between each cut.
So can anyone confirm im on my right path here...? So he choose 4" as his inside bend length, and also the angle in the blue paper. It doesnt have to be 4" and it doesnt have to be a full 90° ( if it was 4" and 45° his numbers would have been 80 and 42,5?) Later he also choose how many cuts he will make, so that number can go up or down (but probably not lower than 2, even if its a 10° bend?). He then measures how much material that needs to go away (75) in the space of the inner bend (160) and leaves space between the cuts (85/4). Right? 🤔
Maestro buenos dias se.puede hacer un solo corte a 30 grados con esas medidas tubo redondo de 2 mulgas y media x favor me podrá dar un ejemplo desde peru y dios lo bendiga siempre
He got this idea while frying a fish 😂, cause to properly fry a fish some people will slice half of the full fish, for fast & full fried... The same method applied but in this case to "bend"
Los 15mm son los que se eliminan y los 21mm son los que quedan. Tiene que eliminar 75 mm en total que son 15x5 y dejar 160-75= 85 que queda dividido en 4 segmenos de 21
The diameter of the actual pipe does not matter. It is the difference in the inner and outer radius of the circle of the pipe he uses. You can see in the very begging of the video he transports on the green paper the diameter of the pipe without measuring in inc/cm.

Yeah but this video only proves math works and is useful.
A much better result than cutting,welding,grinding.
Non of you are wrong. But the video shows pie cutting also works.
You cut all of this and then what you're going to weld it all back together? LOL what's the point of that. There are so many other ways to bend pipe

What decides the distance between cuts and the width of the short uncut distance?? Thank You, JD
How did you get the measurements. Small and big. I did not understand. Sorry. Video is very good.
Excellent calculations and execution. Thank you
Great video. Simple step by step way of doing things.
It works, thanks for tutorial. It takes a longer time, but the result is good enough, if u dont have a pipe bender.
Brilliant demonstration of this method. 👍
Top demais !! Que matemática boa deu certinho 👏🏻👏🏻🤝
Used to make those in the shipyard in the 70’s… out of 300mm diameter pipe, all separate pieces..
they are called lobster back bends
Nice workshop ❤️
Thank you!
Excellent result. But you did specify how you got the results from 00, 15, to 36, 57. How did you come about the difference of 21mm
Excellent very good work good luck 🌹🇸🇦
Thank you! Cheers!
Great idea of bending pipe 👍

I don’t understand how he got his initial large radius of 4 or his 21mm spacing.

Really smart way of bending. I like it a lot.

How u calculate the exact measurements for the triangle cut,the distance between the cut?
You can simulate it on a 3D Design software
Amazing tricks. Super blessed to watch this
I'd "measure" the distance of the exterior and interior curve, to see what is needed to cut for the interior.
He needs to remove a total of 75mm of material within the space of 160mm. He does this using 5 x 15mm cuts which works out to be ~21mm spacing between each cut.
So can anyone confirm im on my right path here...? So he choose 4" as his inside bend length, and also the angle in the blue paper. It doesnt have to be 4" and it doesnt have to be a full 90° ( if it was 4" and 45° his numbers would have been 80 and 42,5?) Later he also choose how many cuts he will make, so that number can go up or down (but probably not lower than 2, even if its a 10° bend?). He then measures how much material that needs to go away (75) in the space of the inner bend (160) and leaves space between the cuts (85/4).
Right? 🤔
Perfekt 👍👌. Danke

Pero no da respuesta a eso
Esta formula solo funciona con tubos de diametro grande en pequeños no queda a 90.

The best thing about this method is that we don't need a bender!
Ok los 15 mm se entiende. Pero de dónde sale el 21? Ya que se intercala la suma de 15 y luego 21
Los 15mm son los que se eliminan y los 21mm son los que quedan. Tiene que eliminar 75 mm en total que son 15x5 y dejar 160-75= 85 que queda dividido en 4 segmenos de 21

Just measure the distance of the 90° angle (both lines), up to the radius curve, add together and you have the length of the radius curve🤨
Great job bro
Nice one
I don't think you have to measure precisely to do this?
there are machines that do this, you spent 1 hour to do this, you will boil it, it is more profitable to buy a patent elbow
that why you should read the title

Where did you get 4 inch?
4" is the radius of the inside bend. It is the number you choose for your requirements.
