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...
That's going to be a badass lawnmower sir!
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.
Excellent calculations and execution. Thank you
Great video. Simple step by step way of doing things.
Brilliant demonstration of this method. 👍
Wow..ang galing mo sir
Top demais !! Que matemática boa deu certinho 👏🏻👏🏻🤝
It works, thanks for tutorial. It takes a longer time, but the result is good enough, if u dont have a pipe bender.
What decides the distance between cuts and the width of the short uncut distance?? Thank You, JD
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.
Really smart way of bending. I like it a lot.
Gracias un gran detalle al publicar las medidas salen muy bien los cortes saludos desde Mexico!!
muita técnica 👏👏👏👍 gostei
Thanks, nice job, manual process..I like this job
Espectacular trabajo!
Great idea of bending pipe 👍
Muito bom o trabalho, que pena que eu não entendi a conta...
Menarik om, saya suka ini.
Undoubtedly, the greatest achievement!
How did you get the measurements. Small and big. I did not understand. Sorry. Video is very good.
very clever, as always, kudos...
love ya style mate, well done. I watch your vids and often go, oh of course, der why didnt I know that.
well done , i love the way you think
Maraming salamat idol may natutunan ako sayo
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.
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.
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
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
Woow so professional😍😍
Perfekt 👍👌. Danke
You are great master...👍👍👍
Very good video, thanks for posting. Thumbs up!
Nice workshop ❤️
Thank you!
Wow amazing idea very good.
Admire the skill, however I'd buy a pipe bender. 😉
Good job 👍
Excellent very good work good luck 🌹🇸🇦
Thank you! Cheers!
Super video 🎉🎉🎉.how to calculate measurement 15 36 51 explain
Good video sir 🙏👌🌹
¡ Congratulations and thankyou vm. It is I need to do with my 4 inch chimney pipe !. ¿ How is the rule to calculate or just copy the numbers write on this video ?
sir jo ye 15 36 ya aur bhi hai ye kya formula me hai ya sabhi aise hi lagana hoga please tell me
Nice, greetings from Kosova.
Esta formula solo funciona con tubos de diametro grande en pequeños no queda a 90.
Great job bro
good job man!
In the UK we call it lobster back.
nossa que trabalheira existe uma maneira muito mais rápida e muito mas bem feita sem cortes
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.
I don’t understand how he got his initial large radius of 4 or his 21mm spacing.
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.
por favor explica de donde sacas los milimetros para masrcar
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
Hello everything is fine. I would like to know how you got to that number in time 3:32 and time 4.32
Nice technic
Good job bro
No estoy claro con las medidas que marca de donde las saca?
Good job! But I can get that same elbow at Home Depot for $6.99. Just saying :O) Thumbs up!
Thanks friend
Мастер класс 👋👋👋👋👋👍
Very nice 👍👍
Simple n practice to do at home
Good job
Nice tutariol
Seems like a good way to strip the wire that's being pulled through there?
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? 🤔
Eso es para doblar a 90 grados, también. Se puede usar el mismo para hacer arcos, curvas más grandes
Hola, por supuesto que si!
@@wtacademy5091 entiendo lo de restar 160- 85, ¿pero de donde saca los 5 ?
@@wtacademy5091 ¿ de donde saca las demás medidas o de donde salen ?
@@carlosanayagarcia6112 Puedes buscar el libro que se llama "Trazado de plantillas para corte de tubos", ahi esta explicado muy bien las formulas y calculos
@@wtacademy5091 ¿ sabes de que autor es el libro? porque tengo uno cuyo autor es FRANKLAND, se llama Trazado de plantillas para tubos, pero no muestra los cortes o medidas según el video, por eso te agradecería, si tu sabes de donde saco las medidas que se ven en el video me las compartas, de antemano gracias.
Serve para qual quer medida de cano
So good
This is awesome, but I don't think I understand your math could someone explain from the beginning?
Nice
nice one 😘
Nice👍
De donde saca las medidas en mm de 00, 15, etc etc cuando marca el tubo??
Pero no da respuesta a eso
Nice technique can u pleasrd re explain the video pleasdd
Buenos días hermano, este dato que significa y de dónde sale " cut =5"
Buenas explicación 💯💯😱
Opa sou giovane .. gostaria de saber aonde como tirou esse valor 21mm
Me explica aonde veio esse 21mm
Bienas tardes buen trabajo a cuantos grados esta hecho el codo si puedes decirmelo y como se hace o como se clacula para sacar otros grados gracias
solo vas haciendo otro nuevo corte
Genial!!! Necesito hacer lo mismo con un tubo de 10,15 CM. o 101,5 mm exterior, como debería tener en cuenta?
De dónde obtiene los valores .15 mm....etc
Good and easy way
Mr Technic, 🙏🏿
Isso serve para qual quer diametro de tubo
Merci
Трубогиб для чего, при отсутствии труба, песок в трубу, пробки из дерева, нагрев, радиус по большей, не нагретой трубе.
how to calculate 15mm 36 51 .....?
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
Excelente,
muito obrigado.
Nice sir
Keep watching
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
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
@@77Avadon77 Y entonces por qué no subes tu vídeo, genio?
Claps, Claps, Claps.!
which cutting disk? Name
Can't go wrong with math and science
The best thing about this method is that we don't need a bender!
Очень чётко, но стоит ли заморачиваться, пошёл купил отвод и сварил, будет 2 стыка всего, если заниматься нержавейкой, то за один калым отобется трубогиб😑
Lama bang, cepatnya aja. Huffftt
What if it was schedule 80?
please upload Elbo 6" pipe
Good
Solo tu te entiendes😢
Paano nyo po nakuha ang sukat nyo sa 15 36 51?. .paki explain po
in order not to suffer so much, it is necessary to use a 90-degree taр
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🤨
