[@poly_hexamethyl]

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.

[@CarlosOmarAlvaradoPeña]

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

[@bradleyrussell1973]

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.

[@trainnerd3029]

OMG NOBODY cares

[@FrailRider]

Hahahahahahahaha

[@RonDoiron-pz3ee]

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.

[@veritasjustus8543]

to think someone had to place a single seed of rice into the ground to make all this happen.

[@RonDoiron-pz3ee]

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.

[@hoperp1951]

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.

[@samheasmanwhite]

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.

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.

[@okjd159]

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.

[@brianwood7480]

That chop saw really got MY attention. What a beast.

How about the load of tubing going over the operators head at 6:22. Would OSHA approve?

[@ajitsinghpurty7729]

Nice video...but it will be more helpful if you add role of the machine during step by step process.

[@MrKotBonifacy]

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.

[@a-fl-man640]

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.

[@RonDoiron-pz3ee]

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.

[@kylehurley5994]

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.
