Looks easy. I think I'll start a pipe manufacturing business now

Thanks for sharing. Love the automation. Educate the world!

This was fantastic. I sat there mesmerized.

one of the steel mills in northwest Indiana is 19,000 acres. That's five times the size of O'hare Airport....they are huge. The real credit has to go to the engineers who design these machines. Now a lot are owned by a guy from India named Mittal....

Informative video Mr.Sunil Mishra,Thank you for your efforts in putting together the video and sharing the same.

WOW, amazing automation, very impressive line. They must either have a damn good cleaning crew, or that plant is very new, as every steel mill I have been is a hell hole, grease, oil, water, mill scale, dust, carbon, refractory sand, etc etc, everywhere. Either way, its a damn clean plant, with a very modern process system! A+++! Great video

really awesome i just like this video, and wanna gives a big thanks to sunil mishra...

Does anyone else find the "music" at the start unbearably annoying?

NYC job

Thank you for sharing this video, very educative

Needs voice over telling the viewer what is going on. Find someone who speaks english and have them do it for you. Otherwise it is ok.

I see clearly the mandrels been warmed to make the hole at 1:32, 1:45 mandrel loading, 1:52 oil film to the mandrels to avoid sticking, 2:03 mandrel charging and locking, 2:05 the hot rod of raw material that is about 3 m long later come out about 20 meters long, 2:38 mandrel hydraulic ramming, 2:42 see how the ram flexes as it is applying inmense force while pushing the mandrel to the material, 2:56 pipe is ejected, being very much large than the initial rod, 3:23 second mandrel pass to final dimensions. you see? easy, all those conclutions using the thinking football.

yah....... very helpfull video for new childrens...........

VERY NICE VIDEO

Video starts @ 0:50

Thanks for your sharing!

Terrible video. Annoying intro. It explains nothing about how solid bar becomes hollow pipe.

this technology is awesome. i am loving it

Amazing!

not clear to me how the steel gets hollow...

Billet Yard to Billet Cutting, Billet cutting to Billet Charging, Charging to Rotary Frunace (Charge Boom) Furnace to piercer inlet (Discharge Boom) Piercer to Mandrel Processing Mill inlet, Graphite Dosing transfer over, Insert lubed mandrel bar, Push throw the MPM, outlet to the Hotsaws, Hot saws to reheat furnace, Reheat furnace to Strech Reducing Mill, SRM to cooling bed, Cooling Bed to Cold Saws, Saws to finishing! Easy stuff! Thats a clean mill!

ive been looking for this video for a long time...MMG mechanical boss WABE...jesco/danieli....

thanks for your sharing the knowledge

Although footages were not so clear , thanks for the useful and correct naration !!😉😬

Somehow this seems to have missed the bit where the hole gets put through the middle which was the one thing I came here to find out.

Nick the hole is made at 3:20 into the video, thats when the ram shoves the hot billet into the piercer. The pipe which comes out the other end has the hole in it.

production of giant macaroni - sadly one cant see much of the actual production process, however its still very impressive - Thanks!

super cool!

England was the top place for quality steel world wide.... Sheffield to be precise

built a plant in Youngstown Ohio that is almost identical. steel goes into rotating furnace and gets a lift up to 2nd floor. The Pearcer pushes a large rod threw the hot steel making a hole. Then it goes through the rollers/reheat coiple times to get the right diameter and wall thickness. Cut to length then off the thread mill

nice

I didnt see any inspection what about wall variations or extrusion defects such as chill tears what lub was used graffle or bristol pads?

Thanks for sharing

Interesting video but does not really explain the process. The Solid bars are heated and a mandrel is forced through the middle. The excess material moved then goes to extend the tube. Its a process that uses a ton of energy. Ive seen them heated by electricity, gas and even microwave ( didn't believe microwave would even work at first). Inefficient? Absolutely. The person that comes up with a method to make seamless tubes without all that additional heat energy is going to be rich.

Large solid rounds are cut, then heated really Freakin' hot, then pressed over a steel mandrel, various steps afterwards to reduce the diameter, and then cut into shorter pieces for further processing/shipping. What part did you miss?

I agree with the fact that they don't really explain how they bore the internal diameter of the steel Billet, but it shows how Blacksmithing is equal parts art, and Industrial Engineering Brilliance, looks like Induction, versus gas fired heat, for the 1st "Heat" if the cold bar, very small amount of scale present as the bar emerged from Induction... induction Furnace heat by means of electric current wound over a refractory lined coil, requires serious supply of electricity, I've been a Union Blacksmith for 30+ years, have worked with both induction and gas fired (blast) Furnaces... conventional arch style gas fired refractory brick lined FURNACE is about 6% efficient, lot of wasted heat, due to space needed for Combustion, induction heating coils surrounds round and round corner square steel bars, heating them from the inside out, almost like a giant microwave oven... resulting efficiency results in continuous controlled heat, usually ± 10 degrees Fahrenheit... scaling is greatly reduced, providing a cleaner outside surface for immediate Hammer, Press or Roll Forging. Scale Flakes of 2400 degree heated steels and Alloys, as bars are brought out of furnace into room temp, flaking off in potato chip thickness, which can have a detrimental effect, in particular, with complex, near-net deep draft closed impression DIE Forging of Aerospace , Agricultural, Mining, Automotive, Railroad, and General Heavy Industrial Hardware components, requiring defect free finish surfaces, a great deal of decision making goes into scale reduction and elimination, as stated, in closed impression Dies, because when scale builds up in a die impression, it displaces the flow of malleable, plastic state steel, for example, an engine crankshaft, with large counterweights that provide rotational thrust in an internal combustion engine, require deep impressions sunk into the Closed Impression Dies, so called, due to the fact, that during Forging, the top and bottom Dies close shut, completely surrounding the billet as it is forged, squeezing out a layer of excess steel into a "gutter" machined around the die impression, to accept steel displaced by the force of the Forge Hammer or press on the workpiece, so, as scale collects deep into a Counterweight impression, it leaves nowhere for steel to flow, and often causing a no-fill condition serious enough to cause the part to be scrapped, but sometimes able to be "cleaned up" in the process of finish machining. It is the Operator, (Hammerman or Pressman) who is responsible for instructing a Blacksmith shop "helper" in the method he decides on, or is instructed to do, on the process sheet for the production run of the specific job, for the control of various methods of hot scale elimination. An oil swab, a hand held compressed air nozzle, fiber glass, coal dust, super fine found glass, called Frit, water jets, protective coatings applied before heating, are a few of the methods employed in between blows as the hammer is "tripped" or the Mechanical Press is cycled, both processes utilizing tremendous force to reduce cross section, thereby refining and compressing internal grain structure, thus tremendously increasing the ability of the Forged part to withstand tremendous amounts of load, combined with high temperature Combustion, such as the atmosphere inside a modern Rolls-Royce Jet engine, making Forged Steel, Titanium, and complex, mission critical Alloys, the Absolute choice for these INTENSE conditions, versus a much weaker cast part. As the now, sadly, closed, and moved to Asia, first Forge Shop I Apprenticed in, and spent 20 good years at, Interstate Drop Forge, in Milwaukee, used for thier Stationary slogan, "FORGED STEEL IS THE METAL YOU CAN TRUST" Amen. Hope I haven't bored everyone to death. I do enjoy what I do, I'm not much good at much else, but I've gotten to be a relatively decent Blacksmith over the years... Grateful for the last of the WWII generation of 'Smith's, just beginning to retire as I began my 6 year Apprenticeship, and the old school way they taught me, green as hell, about the Complexity of the Forge... They were True Craftsmen, Master level Blacksmiths, they don't make men like that anymore! cheers...

Thank you!

So is that the moment, at 3:19, when they bore it out? Looks like they just rammed a hydraulic mandrel into it! I've seen one method where they take a long, rotating drum and just pour molten metal into it. The centrifugal force makes the metal stick to the sides of the drum, forming the pipe, and as it cools it shrinks, making it easy to remove. They just push it out with a hydraulic ram and voila!

they gloss over the most interesting part, making the hole.

if I'm not mistaken this is in Saudi Arabia where I worked with my company PAMIGA for Daniel

SO How does the that large solid steel bar turn into a small pipe ?

good

exactly where the hole come from?

Goddam 😳 I wonder what temperature 🌡 those are to be glowing like that?. Do the run electricity through those to get them hot like that?

Amazing and grand sight

How do they make the hollow center?

where I can find a Equipment (machines which is makes steel pipe ?)

Not a word spoken. Just horrible distracting music. What a missed opportunity to educate people.

Cast ductile iron is what I see used for bomb casings. Cheaper than cast steel, but ductile enough not to break during shipping and handling.

procsess is good with qualityand quick process,what is time to make one set of pipes

There is an extrusion punch that runs in the ID to make hollow inside

This video shows the metal and pipe moving around; but I would have liked to see the part where the billet is pierced.

It would be helpful if we have some explanations along the way.

I think what the other guy was trying to say is it's easier to cut a long pipe to a short than it is to cut a short pipe longer.

So how the hell do they get the hole inthe pipe?

I think its because a lot of manufacturers have been running into problems with cuts being too short. No matter how many times they cut it, it's still too short.

The beginning of this video is the same sound I have within a nightmare. Why would you ever pick this?

CAN YOU PLEASE ADVISE ME WHO WAS YOUR CONSULTANT FOR THIS PLANT.

i would love to how the heck the hole is made!

Plymouth Tube Co. - Hot Mill Winamac, IN. We do the same thing

Doesn't show how the solid tube is converted to pipe. Is a die run through the pipe?

hot pipe transport method is technically very good

The mighty poke!!

Let a 2 new grader make this video so we can learn something like how do you make the tube?

Is this steel used to make bombs and scarey stuff like that?

*knock knock* I'm here to lay the pipe.

we are seamless manufacturer and exoport,which is produced by punching billet .

cool

se ve que van de aca para allá, pero en que momento le hicieron el puto agujero a los caños????

Dear Mr. Sunil, this is Amy from Jinan Possible machine, we are the manufacture of marking machines in China. Our Pneumatic marking machine can mark and engraving serials number and letter on your metal pipe, if you need, pls contact us directly

Where is this plant i want to see it personally please let me Know Mr.Sunil Mishra

Thumb down, too long intro. Btw, rest of the video was nice to watch.

Molto interessante

OK I see everybody is confused as though hope it came out hollow. It got extruded and central hollow portion is because of mandrel. all of this happens inside the dies, hence is not visible.

and I've taken DOM tube for granted all these years

the hot steel roll went into some magic machine and came out seamless pipe

My friends, this is where they make the internet. It's not brought in on a big truck.

Ah but can it achieve DNV OOR spec?

When procedures are not explained, the video gets boring very fast. It was like watching family movies of which you didn't know anybody. Thumbs down on what could've been an educating video.

Poor video,but the automation at this factory is excellent.

THE SOLID BILLET GETS PUSHED INTO PIERCER ROLLS ON THE OTHER END IS A LONG ROD ( LANCE} WITH A HARDENED POINT THAT PUTS A HOLE IN THE BILLET

how they are making hole in the rod, not clearly understanding

you really dont get a god look at the rotary piercer, but its there either way. cool stuff

have you work there?

I´ve been googling to research this subject and all I get is this waste of time video. KZfaq is awash with useless videos from the india which don´t really understand the subject with which they would like to be associated. I can´t help thinking this is done to gain Kudos at work more than provide a service.

Long intro. Other than that, informative

Which temp tp 316l

Making bombs out of seamless pipes would be an extreme waste, these will probably end up in some high-pressure industrial application... Bomb casings (the fragmetary ones) are usually made out of cast steel, since it shatters into shrapnel better...

This reminds me of Terminator 2 in the steel manufacturing plant.

Miten BD insuliinikynän neulan reikä tehdään?….How to BD insulin pen needle hole made? ....

How is this song called?

So.. You took this video from youtube and put it on your own channel? I don't get it...

Why do they make them so long if eventually they cut the pipes into shorter sizes?

How do these things hold up against jet fuel?

it is magic

LMFAO at 4:25 that machine says KOCKS on it! OK so yea for about a min I was 5 yrs old again!

We weren't shown how the bar was made hollow into a pipe.

Please clarify max diamentr for seamless steel pipe that can be manufactured

steel tubes of "peace".
