- Explore the production processes of square steel pipe from steel sheet and round pipe
In this video we will explore the production processes of square steel pipe. There are 2 basic production processes for square steel pipes:
1. Producing square steel pipe from steel plate. The steel plate will be removed from the coil, cut to the design size and shaped into a square steel pipe
2. Producing square steel pipes from round pipes. The round tube will run through the injection mold to shape into a square steel tube. This method is applied to large square steel pipes, which need high strength and bearing capacity.
In addition, in the video, we will also see the bolt production process at a factory in Korea
Thanks Auntie , I would come back to borrow some more 🗣️🔥🔥
Little john liked this video
Little John have an infinite supply of this
Brought back memmories of my time working in ERW pipe mills ! Thnx !
You have a very clean and well organized factory, very well initiated. 😊
Little John is liking this one
thanks to these people, I was able to expand my 0m² apartment to fit my 3 billion kids 🙏
Really super awesome!!!
*Let the Sunshine In .*
Thank you, very interesting.
Lots of nice machinery! It must have taken quite a it of thinking to design all that, and also to get it set up and aligned to run accurately. Every single one of the numerous rollers and guides on that line has to be carefully adjusted in 3 dimensions, and run at the right speed, etc. etc.
Amazing that you have this much access.
Piękna produkcja rur kwadratowych. Pozdrawiam z Polski.
thanks so much
Truly extraordinary friends 👍
Isso que é um projeto muito delicado máquina programada
Good work bro
I have always wondered how round and square tubing was made, thanks.
Tt
It's all a progressive set of rollers.
This is one method. The other is called piercing a billet.
I stay awake at night thinking about it.
Used quite a bit of Square Tube when I was in the business, got a lot of steel from Poland and Canada but can't ever remember any coming from Korea.
شيئ جميل جدا شكرا لك
Someone dreamt this up in their sleep then in morning he builded the thing and it worked like a champion.
Công nhận máy móc được con người chế tạo ra thật là thần kỳ !
É bom saber como as coisas são feitas.
I was at Welded Tube in Chicago area and the did thick wall tubing from sheet rolls. They had to get the curvature out of the rolls by going up almost 30 ft then into floor the same distance, then had rollers like the thin wall shown. The had a chop saw ( 5 foot diameter) the would follow the tube while cutting.
That chop saw really got MY attention. What a beast.
@@brianwood7480 If I had a cell phone that took vid I would have posted it. Amazing to watch.
Que agradable ver el proceso de fabricación, increíble cómo realizan las diferentes medidas, éxitos 👍
Steel procesing. Good
giant metal production machines
amazing 😮
The best part is always at the end of the video, and most often covered up.
Felicitaciones a nuestros genios a los ingenieros a los grandes creadores de las grandes industrias soy de A R G E N T I N A Santiago del Estero me llamo cesar Toloza
magnifico e increible
Totally tubular man !!!
VERY COOLPRODUCTION PROCESS!! BUTT.., FROM FLAT , TOO ROUND, THEN STRETCH TOO SQUARE.. /???
COULDA.., WENT TO SQUARE AND SAVED, OHH THOUSANDS OF HOURS IN ROLLER MAINTENENCE...
No room for erw
Amazing to see. I didn't know the tubes ware made like that.
please visit my channel i also make videos related to truck Love from pakistan🇵🇰
Only in korea
That is one method of several.
good！
Soo kool
The guy standing under the load of square tubing is a big liability
however high a load is, that's how far to stay away
Workers are cheap in chyna!
All I could think about was that this factory is a maintenance superintendents nightmare.
Good NIC 🤣🤣🤣🤣🤣🤣🤣
nicely done. i would love to see the inner workings of the machine that changes the round pipe/tube to square. that line must be a bear to maintain, let alone build.

Actually it’s four beveled roller spindles that form the four corners of the square tube
Maintenance was the FIRST thing that screamed at me.
@@brianwood7480 Just bearings. Ones lack of understanding does not increase the complexities of the world around them.
@@Look_What_You_Did is that all you see, bearings?
Extruding that large square tubeing from round pipe in ine step is amazing and I did not even see any kind of lubrication. Would think the steel would tear being dry.
Usually the lubrication is inedible rendered animal fat.
@@harryniedecken5321 wow !
Not for high pressure, for high end applications there are seamless pipes.
Nice video...but it will be more helpful if you add role of the machine during step by step process.
I guess it's right there... but in Korean ;-)
Actually, the process is pretty self-evident - a steel sheet on a roll is cut into strips, those strips go through series of rollers thay roll the strip into a round pipe, which is then welded up, any excess of material from welding is cut off, and then the round pipe is pushed through more rollers that squeeze it into square section. The saw cuts it to desired length, and basically that's it.
nice
I ran a slitter at Worthington Steel in Columbus Ohio years ago.
That's dangerous work.
I liked it though.
At 6:20 a very dangerous lift of a bundle of tube is being made over the head of another machine operator. Yikes! I guess safety isn’t priority in Korea.
Dangerous indeed.
How is the welding done? Lengthwise... In other words, what kind of welding process/technique?
I think it is Electric Resistance Welded (ERW) between two points with no filler metal. But I'm not 100 sure. It can't be a tig process because I can't imagine argon could be used with all the coolant on the pipe.
Best part ye he ki ispe kharch kiye pese india me hi rahenge
Omg. If it has corners, it’s considered tubing. The difference between pipe and tubing is pipe CONVEYS material, liquids, or gases, where tubing is only used for STRUCTURAL purposes.
OMG NOBODY cares
Hahahahahahahaha
No quite correct. I worked at a Seamless tube mill for 30+ year. We made tube for deep oil well drilling and casing. We also made square tubing for structural purposes. The difference between a pipe and a tube,…the pipe is measured on the inside diameter, the tube on the outside diameter.
to think someone had to place a single seed of rice into the ground to make all this happen.
I worked on steel pipe. A pipe is measured on the I.D, Eg. a schedule 40 pipe, 2” , id 2-1/4” o.d. A 9-5/8 tube, which is a common size for oil well, is measure 9-5/8” by .500” wall, etc. we could produce a seamless tubing, 40’ long.
6:27 Standing under an overhead crane flying tons of product? Not too conducive to longevity I think.
Not to mention the spread of the slings, must be one smooth crane
In China all workers are expendable cogs in drive to produce cheap products and put Americans out of work.
@@maplemanz unfortunately China has some very sophisticated manufacturing, as well as mass produced crap ! They are frightening competition !
@@ag-om6nr this is S. Korea btw.... no biggie. but yeah ur probably right about China. the hard thing is knowing whether you're getting crap or great quality.
Good NIC 🤣🤣🤣🤣🤣🤣
Nice to see these machines and processes, but you really MUST add text / narrative to describe the machines, process stages.
Steel coil, unwound onto a slitting line. Slit into individual coils. Individual coils placed onto a multi stand forming line, formed into a round and seam welded. A scalper to remove excess weld then into a water cooling tank. After cooling the round welded steel tube goes into a multi stand forming train to convert the round tube to a square or rectangular section. Finally a flying saw to cut to exact finished lengths. They only require inspection / testing to ensure weld continuity, and dimensions. Then into the box for supply to the final customers.
6:31 Drawing steel pipe through a square die on a draw-bench. The end of the steel pipe has been cut and swaged to produce an end that can be gripped by the draw-bench jaws.
8:48.... making bolts, nothing to do with making pipes, completely different product and techniques.
I'd like to add that the machine at 2:00 is a sheet accumulator, since it is a rather neat machine but it is difficult to see what it does or how it works.
It temporarily stores sheet to allow the production line ahead to operate without stopping, even while the sheet input is stopped to weld a new roll to the tail of the old one.
The input sheet is wound onto the outside of the big wheel and unwound from the inside of it, then there are some rollers to curve it out from the middle so it can continue on. When the big wheel rotates clockwise it takes in and stores up sheet, when it rotates anticlockwise (as seen here) it does not take in sheet and it releases the stored sheet, if it is stationary then it is taking sheet in at the same rate that it goes out. The big wheel does not grip the sheet, it is covered in rollers so the wound-up sheet can rotate around it.
seamless steel pipe China factory, welcome to consult
👌👌👌
pipe is round, steel tubes are square and also called 'Hollow Structural Shape', this term applies to square as well as rectangular parts
remember Jerry, (and Brian) from Worcester MA? you two came here. try to get in touch with me if you can, try here first
Talk about putting a round peg into a square hole!
I'm still looking for the square pipe, although I do see some square tubing.
And yet when you look in the mirror you see a loser.
Imagine the amount of force requires to push a round steel tube through a square hole....
It's slowly formed a little at a time into square.
Or pull a round tube through a square hole...
Imagine the electric bill!!
how much cost in produce custom square tube? Because i dont finde 42.3mm*42.3mm only have 40*40mm and 45*45mm. nor 42*42mm
Esto se fabricaba en España y lo dejamos ir todo para china. Una pena, ahora manejan los precios como les da la gana.
All these processes have one thing in common. They are very loud!

السلام عليكم ورحمة الله وبركاته
Is it a pipe or is it a tube? I believe you will find it to be a tube.
Making pot metal. You know the stuff they make patio furniture out of that breaks when you sit in it.
They must transport you in cargo... lol
@@realemonful Funny, very funny.
кабистан цымер приходилось натакой приблуди работать👍
I never knew that milk was required to be squirted all over the metal during the manufacturing process! 🐄 Moo!
6:21 Safety First :D

Need to wave the camera around a lot more. I could nearly see what was happening.
Camera moves way to fast. Stability, please. then the critical processes (closing and welding) are shown in just a few seconds, spend more time on these.
Yêu Đức Phúc.
How about the load of tubing going over the operators head at 6:22. Would OSHA approve?
Хе,хе. Гайки тоже кувалдой закручивают.
no chains or racks were the coils are stacked on top of one another
i want to operate a press that size
Tube is tubular. Pipe is pipular.
Where are you located in Korea
_Yung_ Steel Co. Ltd..
대한민국 화이팅.
7:20 they can actualy put a round peg in a square hole
Who say's you can't put a round tube into a square hole these guys do it all the time
Did I see this right, square tubing coming from round pipe?
Yes you did ! They were using ERW ( Electric Resistance Welding ) . It is a continuous process with a flying cutoff to standard lengths .
It did bring back some memmories !
6:24 that a dangerous thing to do. I'm surprise nobody has gotten hurt yet
Who says they haven't? The Chinese don't care about their people. They have billions. People are an expendable commodity to them. Definitely a country worth boycotting.
Why is it so hard to find 1 1/2 X 3 1/2 rectangular tube?
Watch your fingers! 😂
whale oil beef hooked, i had no idea
No hardhats. No safety glasses. And somewhere in the middle there, a load of square tube being crane lifted with a man standing directly underneath the load. This is how costs are cut in manufacturing......but at what cost? Safety is worth something. A lot.
Says the ameritard... buying on price alone.
That machine is a mile long!

Can anyone tell what is the name of this Korean Company ???🙏
How mach?
Those machines came from America after they closed a plant here 😢
Nope. Nice try at another ameritard lie.
I wish it was louder
Thats gotta suck to have no safety standards. No one is wearing any PPE.

Is that filmed with a smartphone in a shaky hand? Too bad because it could be so interesting 🤔
All the toxins they breath, gives them the shakes.
