Production flow - from billet to high tech seamless pipe.

[@seventhson27]

I used to work in a mill in the US that made this kind of pipe. The process was a bit different, but many of the steps are certainly recognizable. Walking through the doors of the plant was like walking 40 years back in time.

[@HaraldFinster]

Very nice and instructive video. Good to see that you concentrate on the actual processing details and explain it in a clear and factual manner. This makes a nice difference to the usual emotional and dramatizing style. It would have been nice to see the initial piercing process ("Mannesmann process") in more detail. I am aware that it is hard to capture this on camera.

[@mehmettemel8725]

I think it's process secrecy that's why.

[@HaraldFinster]

@@mehmettemel8725 The process is very old and well known, actually. It has been invented by the Mannesmann brothers in 1886. If you look up "pierce rolling" you will find a lot of information on the process.

[@bardmadsen6956]

@@HaraldFinster Is it the same as Drawn Over Mandrel? I've been looking for the right material since the early 90's, happen to know how to buy it / find it? Last time they told me I would have to buy rail cars of it, and wouldn't sell a sample to machine the prototype to see if it would work for my needs. They even asked what I intended to do with it. I leaned forward to see their testing like I could see the range and in metric... I need the inside concisely done.

[@HaraldFinster]

@@bardmadsen6956 To my limited knowledge "Drawn Over Mandrel" is used to bring welded tubes to a defined diameter. In this case the tube is formed from sheet metal which is bent to the shape of a tube. The seam is welded inductively. The tube is then drawn over a mandrel to finish the size. The Mannesmann piercing process is somewhat similar. It makes use of (usually) two driven rollers running in the same direction. The round billet is located between the rollers. As the distance between the rollers is slightly smaller than the diameter of the billet, the billet is forced to a somewhat elliptic shape. This loosens up the structure of the material in the center of the billet so that a mandrel can be forced into it and forms a tube. As the rollers are slightly skewed the billet is drawn onto the mandrel and shaped into a continuous tube. I am not sure if I am allowed to include a link here, but the following video explains the process in an extremely demonstrative way. It is actually made for kids and in German language, but the demonstrations are self explanatory: kinder.wdr.de/tv/die-sendung-mit-der-maus/av/video-rohre-100.html The demo starts approximately at 03:00. Again, I am not an expert and just privately interested in industrial history and photography. I hope this is helpful anyways. Harald

[@bardmadsen6956]

@@HaraldFinster Thanks for the video, that shows what I was looking for. If I ever find what I'm looking for I need it machinable. DOM seems the way to go, somewhere around $20 a foot last time I looked, the problem is that I need them over sized to the inside diameters, then machine them to fit 'telescopically'. Three would be perfect, two might work, still I can't find any to buy. I'm getting close with the machine to make the machine without a source for material, the work is missing... I just love very long term projects. Years ago I was so desperate I asked a cast iron place and they seemed like they were on something, face to face, like they were stuck in a mode of me working for them when I wanted them to work for me. I've thought of doing something myself, but man that is pretty hot, not sure about the learning curve in dangerous territory. Aluminum casting is about as far as I will push it.

[@johnroberts3824]

I used to perform field service on industrial infrared pyrometers. I saw this very process at a plant in Youngstown, OH. Very cool. They also had a steel smelter which made the billets. I wandered all over the place.

[@SwissplWatches]

That is so incredible! Elements we take for granted every day require so many steps and research / development. Impressive!

[@catxnc]

beautiful setting for a plant. saw no humans performing any repetitive tasks. nice.

[@jrfutube2013]

As a mechanical engineer, I can appreciate the magnitude of "metallurgy" involved in producing different tubes for different applications ⚙

[@-_-----]

Damn, this is cool. I love how thorough and efficient the Quality Assurance processes are... and how some diligent, common-sense steps can transform an otherwise 'commodity' item (boring, simple pipe) into a highly-refined, individually-verified premium product. Modern industry is really a beautiful thing.

[@marbleman52]

Back in the 1980's through the 1990's, I worked in a small manufacturing shop where we made gym equipment. One of my jobs was making a weight lifting bar that is used in competitions. The shaft was a special steel called ETD150..Elevated Temperature Drawn. The shaft started as a larger diameter and while the steel was still red hot, it was drawn through a smaller diameter device which compressed the red hot steel down to a predetermined diameter. It also had a very specific 'recipe' of various chemicals which gave the shaft a specific performance requirement, such as being able to put up to 500lbs of weights on both sides that will cause the bar to bend but come back straight once the weights are removed. The chemical make up of the bar also gave the bar certain machining characteristics. Over the approximate 18 years that I worked there, I made several tens of thousands of bars.

All US submarines use seamless tubing. It is believed that the sinking of the nuclear submarine USS Thresher in 1963 was due to a failure of a seamed high-pressure tube which allowed a jet of pressurized water to short out the main electrical panel which lead to the series of events which doomed the submarine.

Why is no one hearing the vicious circle. We dig into the mountain for ore, then burn coal or gas to melt the rocks into steal only to make drill tubes to extract the oil. 🙏🏼

[@-_-----]

Agreed - All of this engineering brilliance should be being put to better ends. It breaks my heart when I realize the Quintillions of effort-calories expended supporting the Oil industry. The entire Oil industry is functioning off the principle Orwell described in '1984' -> Employing people by digging trenches and filling them again. Robert Bussard (RIP)'s Polywell (inertial confinement) fusion reactor? Nah... down the memory hole, and Billions wasted annually on the perpetually-inadequate TOKAMAK. Kirk Sorensen and the Liquid-Thorium reactors he's basically engineering from scratch? Nah, ignore him.... give him no money, and bury him in ridiculous regulatory hurdles. ...to say nothing of the 'weirder' energy stuff which may work, or the dozens of other mainstream projects to both generate and conserve energy. The solution, though, is for the average person to lean farther INTO industry, not OUT of it, because knowledge and passion for engineering leads to a disdain for inefficiency, and a deep desire for better and more beautiful-engineered systems.

I work at a big steel distributor and we refer to this officially as DOM tubing. Seems weird since it's more like pipe in my mind. "Tubing" makes me think of structural tubing. But in this video the DOM tubing looks even more like pipe since they are threading it.

[@TlD-dg6ug]

@@blackburn1111 So tube is measured from the outside, pipe is measured from the inside. Tube can be any shape, pipe must be round.

[@blackburn1111]

@@TlD-dg6ug hmm. The drawn over mandrel stuff we have has ID, OD, and wall thickness specified. Perhaps having all 3 of those dimensions accurate is what makes it tubing then?

[@TlD-dg6ug]

@@blackburn1111 Firstly, not all tube is seamless. Your seamless tubing can be called out like that, non seamless cannot. So by definition a pipe is a connection or passageway for something. As such they are measured to the inside (gas,oil,etc). A Tubes are mostly used for their outside measurements.... Such as fabrication. Pipes are called out from the i.d. because the only thing that matters is flow rate as long as there's enough material to hold the pressure. A 2" pipe could have an 8ft wall thickness and just be a more substantial 2" pipe. But a 2ftx2ft tube with 8ft wall thickness would be considered an 18x18 foot tube. Basically all things equal, if you used one of these pipelines for structural use instead of a carrier, you would call them tubes. Tubes will always be more dimensionally accurate, because you're building something with their shape. Not transporting. Does that make any sense?
