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.
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.
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.
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.
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.
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...
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.
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.
The mill that makes square pipe out of seamless tube has 3 stands, we V shape rolls. The tube would be heated at forging temperature, then fed by a conveyor, into the mill. The first mill stand would grab the hot tube and as it roll through, would slightly make the tube ovalish, the second stand would make a square tube with round corners and the third stand would finish the square shape. The tube would come out of the last stand, slightly hotter, due to compression and friction. It would then continue down the line, now a bit longer than 40 ft., up to a cooling bed, driven by chains. Once cooled, they would be picked up by a 10 ton crane, 10-12 pieces at a time and stored in huge bins. That mill could produce 3-1/2” to 10” square tubing.
@@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.
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.
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.

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.
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.
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 !
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.
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.
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.

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.
Excellent video, but what is the last cube before the cut and what does it contain?

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.
Totally tubular man !!!

The best part is always at the end of the video, and most often covered up.

Usually the lubrication is inedible rendered animal fat.

Someone dreamt this up in their sleep then in morning he builded the thing and it worked like a champion.
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.

That is one method of several.
pipe is round, steel tubes are square and also called 'Hollow Structural Shape', this term applies to square as well as rectangular parts
Where are you located in Korea
All I could think about was that this factory is a maintenance superintendents nightmare.
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.
Nice video...but it will be more helpful if you add role of the machine during step by step process.

Not for high pressure, for high end applications there are seamless pipes.

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.
I ran a slitter at Worthington Steel in Columbus Ohio years ago.
That's dangerous work.
I liked it though.
Soo kool
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 !
How about the load of tubing going over the operators head at 6:22. Would OSHA approve?
Need to wave the camera around a lot more. I could nearly see what was happening.

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!!
I'm still looking for the square pipe, although I do see some square tubing.
All these processes have one thing in common. They are very loud!
Talk about putting a round peg into a square hole!
Is it a pipe or is it a tube? I believe you will find it to be a tube.
É bom saber como as coisas são feitas.
nice

Why is it so hard to find 1 1/2 X 3 1/2 rectangular tube?
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
i want to operate a press that size

The correct term is HSS ( high strength steel ) for the square shape
@@Look_What_You_Did the shape is referred to as H.S.S. that’s what tubes Steel is marked as. Lol. Dummy
The bending and rolling increases the strength of the steel.
It’s square tube not pipe that’s a tube mill pipe is not made that way
I wish it was louder
