- One of the most frequent questions we get from customers is “What’s the difference between pipe and tube?” In this video blog, Operations & Development Manager Jason Jackson discusses some of the main differences between the two.
you know you are getting old when you start watching this kind of videos for no reason :D
I have never wondered what the difference between these two things were, but I found this video very well done and the explanation fascinatingly memorable.
This has been keeping me up nights for the last week. Thank you for helping me sleep again.
Dude, I didn't even know there WAS a difference. This was very instructional.
Very helpful. I'd love to see more of this type of content produced by you all. Thank you for teaching me something.
I'm a novice welder & kinda learn as I go .... with that being said Steven at the Doraville/Atlanta location is always nice to me & doesn't get mad when I ask stupid questions!!
Thanks for making my welding projects more fun Metal Supermarkets of Atlanta
Ps..... I love the left over room!! I always find good pieces to make things with
This is the kind of advertising I can get behind. Wish this was longer. Maybe give some info on material selections, fabrication preperation, manufacturing or common sizes/selections. Personally, I would have no problem watch a 10 min or longer video =)
What makes tube suitable for structural applications? Are they tempered it treated or quenched differently from pipe?
Great question!
now i can sleep easy
Thumbs up, I thought they were the same, just different words.You learn something everyday.
Tube is measured by outside diameter, the pipe is measured by inside diameter below 12 inch,the pipe is measured by outside diameter above 12 inch
according to manufacturing system pipes are classified in 3 types seamed pipe,seamless pipe and spiral pipes. pipes are commonly used transportation system like liquid,gas and powdered form of materials.sometimes structural work also. Tubes are used in structural constructions. Commonly tube shapes are rectangular or square. Tube specifications like 18 gauge (1.024 mm)or 16 gauge (1.291). This is only specified tube wall thickness.Not used scheduled system. That is only used in pipe specification. Pipe specification like scheduled 40 or scheduled 80.
Pipes have nominal diameters that are neither equal to the outside nor inside diameters but somewhere in between. Tubes are always exactly sized on their outside diameters. Tubes are also used for pressure fluids such as refrigerants, gas and house water systems like sinks, water heaters and bathroom fixtures.
Good summary, I always wondered about that. I don't understand your remark that pipe outside diameter never changes, since pipe is sold by a defined internal diameter. Charts of different schedule pipe do show variance in wall thickness with both internal diameter and schedule.
I guess "never changes" refers to the evenness of OD for a given pipe. It means that even though pipes are specified by their nominal internal diameter, this parameter is not as consistent throughout the length of the pipe as compared to OD.
Oh, good point, I didn't think about variance along the length of the pipe.
A 1" pipe refers to O.D. it will be available in different schedules 40, 80... Giving different I.D.s
But the video says pipes are measured by the inside diameter. This is how they're sold but maybe not what actual size they are. Maybe the reason the O.D. never changes is so that couplers will fit pipes regardless of what schedule they are.
Watch the video again and see if you can spot your mistake.
Piping & Tubing is very important to Welding & Design Engineering. You have a great series of video-RUclips.

Now all I need is to wait for this exact question to come up in a pub quiz.
Thought the same thing!
Great Stuff Mr.Jackson
Thanks for the video! We sell lots of steel tubes and sometimes get people asking for pipes.
Good info! Just keep it to 1 camera angle....poor dude already has a hard enough time reading the prompter
You are both cruel nasty people -- and entirely correct.
Haha you beat me too it!
Prodigious Pi yep they made him look goofy as hell lol
Prodigious Pi yep that camera angles where the narrator's face is looking @ a non existing audience has been so over used that it is now irritating. It expresses a amature video photographers not the intended professional look
You only notice this after someone mentions it
You said "usually" with pipe being sold by ID, not "always", which is especially true here in the UK :-) We have a weird situation with water pipes - until the 1970s we used to have standard pipes with ID in inches (especially relevant in the old days of thick-walled lead pipes), now we measure them with OD in mm. Most pipe sizes are different enough that you can't interchange Imperial and Metric, but a 1/2" pipe is interchangeable with a 15mm pipe, even though half-an-inch is 12.7mm.
Tube, of the right sort, is often used for pressure applications, even if you don't sell that type. I have run stainless tube for decades for applications that hold thousands of pounds pressure. Most industrial instrumentation utilizes stainless tube. Larger tube is used within industrial heat exchangers and furnaces. It might be well to note that ANSI B31-3 and other ANSI codes make no distinction between pipe and tube in terms of how they are inspected and used, so make sure you're using a suitable grade.
Extremely helpful.
Knowing the material's true dimensions is key to selecting the proper machine and tooling for your application. PIPE sizes are measured by ID., with WALL THICKNESS referred to in terms of SCHEDULE. TUBE sizes are based on OD, and WALL THICKNESS is referred to in gauge sizes. For example,a 1-1/4 in. SCHEDULE 40 PIPE has a 1/1/4 in ID, and a 1.66-in. OD. Whereas a 1-1/4-in TUBE .65 WALL has a 1-1/4-in OD and a 1.120-in. ID.
Helpful, yes.
For us, who are novices, would you consider redoing this video with more specific examples? Or, perhaps doing an intermediate or more advanced video with the examples displaying the pipes and tubes variances along with real-world examples of their uses.
Only experience in the market will teach you this.
"Usually measured in inches or fractions". Pretty sure only in three countries. Besides the naming and sizing differences, would I get problems if I used tube as pipe or pipe as tube?
antalz
Uh, you SURE about that? Gas pipe, for instance, needs to be compatible with stuff installed as much a a century ago. Wouldn't surprise me if certain (nominally) metric nations retain inch-based pipe for continuity reasons...
Can't speak for industry, but my local Hornbach has only metric pipes and tubes, in plastic, aluminium, steel and PVC. Some of the fittings are inch, like shower taps tend to be 1/2" or 3/8"
bcubed72 - there is a far simpler solution than using imperial measurements:
use normal metric and if you need to connect them use an adapter.
And as it is used for well over 100 years by now - no, there aren't many things if any at all left that use other measuring units.
Those shower taps are probably not inches though. But in the old measurements of the country you buy them in. And pipes can often be bought in both the old and in metric measurements and sometimes in inches aswell. Although I'm pretty sure gaspipes have to be metric.
I have never seen a length expressed in anything other than imperial or metric units. All the ancient european units have disapeared. What kind of other units are you thinking of?
I need to make a nerf pipe for my Jeep Wrangler. Should I use pipe or tube? Going to cut the nerf tube off and try and weld on to the existing metal brackets. Manik went out of business. They had a warranty, Thanks for the clip, mate!
hi Jason Jackson. Thank you so much. Your English is really attractive.
Perhaps you can answer a question I have been trying to get answered for years. What is the preferred pipe OR tubing you want to use to make a hydraulic cylinder? Thank you for your time.
Tube. Lots of extra material to bore to exacting dims.
Those off main axis camera shots are just weird.
Very weird
Agreed.
1:04 says pipe is measured by inside diameter (nominal diameter) and the thickness
1:48 says outside pipes never changes but inside does
So basically when we want very specific flow we should carefully to choose the pipe. Because not all 1 inch pipe have same inside diameter???
Yeah, I caught that too. Did he misspeak?
@@wsg4847 I think so because he was talking about tubes @ 1:48
Pipe 12” and under is that size in name only and the od is a bit larger than its name but does not change. the id does change based on sch. Pipe 14” and up has an actual od of said size and does not change. Again Id changes with sch.
That makes even less sense than the video description. Good work.
What I know: OD changes with *both* ID and schedule. Further, Pipe that is used for refrigeration or A/C (ACR) is called tubing and is sized by the OD.
What I suspect: In the end, you have no way to identify or specify what you need for a given project because the entire industry is run by turtles. Stupid, mean, bitterly jealous turtles.
There are standards for pipe or tubing sizes, but they cannot be counted on when ordering as only two or three people knew what those standards were, and they died without divulging their secrets, so every vendor just makes up some random dimensions. You can specify whatever you want for a phone or online order, but you'll take what the vendor gives you and like it.
If ordering in person, you *must* take a piece of pipe to the vendor and insist on seeing a sample so you can test fit your pipe to theirs. That's the only option that has any chance to work. Take a turtle hammer though.
Giblet535 and we did not even cover GRADE in today's lesson.
Giblet535 I always order by sizes measured in turtles, but don't get me started in the Schedule Snapper vs Schedule Painted size differences!
Giblet lol maybe you should take a basic class in refrig or in plumbing or pipefitting. Any apprentice has to know that stuff within a couple months or they are useless.It is done like that so that anyone can understand how to size and order pipe, and there are no screw ups because everyone uses the same standards and terms. Same reason you can order a Tee with 3 diff size holes and always get the right piece.... STANDARDS. All you need is a measuring tape to order the proper piece if you have a sample in your hand.
Is the metal grain in the same direction in pipe and tubes ?
Great question.
I would appreciate more if you explain a bit more ability pipe dimensions. And about fittings as well. Thx.
Has steel become on average lower quality over the years? I ask because there are steel fences from the fifties and before in existence still serviceable, while whole subdivisions of pool fencing is shot after seven to ten years, and the replacement fencing drips rust stains from the inside of the tubing shortly after install.
walter kersting the chlorine vapor from pools is very corrosive and damaging to steels, even stainless.
Is this the one that Chris of B is for Build always talking about? haha I googled the difference between pipes and tubes and your video is the 1st to pop out
I enjoyed your video. It was very helpful. Very much appreciated! Thank you!
Crystal clear...
Thanks
I work at tenaris a huge oil pipe maker, and all our pipe is o.d. Dimensions, and our tolerance is very tight.
Pipe is always referred to by it's OD or outside diameter, wall thickness and grade not ID or inside diameter. For example 16 inch .375 wall thickness X52. Pipe has standard sizes and schedules it can be manufactured seamless, ERW welded, DSAW double submerged arc welded or spiral welded.They don't call me Westexaspipeliner for nothing.
If you were a good Westexaspipeliner you would know that sizing is different for pipe between 1/8'' and 12'' and above 12''...... a first year apprentice needs to know that for first block.
Awesome! I would never of known that. Thanks Meetal Supermarkets. Thanks YuPipe
Thank you from Brazil.
...and what's the difference between a Joist and a Girder?
Simple - Joist wrote "Ulysses" and Girder wrote "Faust".
Pipe - NB (Nominal Bore)
Tube - OD (Outside diameter)
All other information is fluff & minutiae.
myblueshades This and thank you
Thank you crazy Jesus;)
So, if you measure the outside diameter of a pipe, it becomes a tube.
Either that's too easy, or I'm so confused!
Very helpful
Can you explain which one would be best used for a vertical post to withstand side pressure as from a sun sail?
Dude! Well done! Very informative and very professional! Thanks for the video!
correct me if i'm wrong but I feel like he made a mistake at 1:59 in his presentation by saying, "OUTSIDE NOMINAL PIPE DIMENSIONS NEVER CHANGE BUT INSIDE DIMENSIONS DO". I don't think thats right. a 3" schedule 40 pvc pipe will have a smaller outside dimension from a 3" schedule 80 pipe because pipe diameter is measured inside to inside. so that would mean the inside dimension is still three inches and the outside dimension would in fact, have changed.
please let me know if im understanding that correctly, thanks
You are wrong and he stated it correct. How are you going to attach a piece of schedule 10 pipe to a piece of schedule 80 pipe if the OD are different? Just read a piping size chart, you will notice it.
I commented about the stall bars/swedish ladder on another video. I think I should either go with galvanized pipe or steel tube (maybe stainless). The horizontal rungs will be around 1.25" outside diameter by 39" length. If I go galvanized pipe, do you think a 0.133 wall thickness will work? If I go steel tube, what gauge would work? Should be able to hold maybe 400 pounds to be safe.
Hi, I understand the tube can come in different shapes. But is a round tube the same as a pipe, if they have the same diameters (inside and outside) or the same thickness? especially with the same strength (bending, torsional ...) they are made of the same material? Thank you.
what are the specifications for tensile testing of hollow iron pipes
I think pipe measured in NB(Nominal bore) rather than inside diameter.
That's something I never knew, thanks
Conduit?
Thanks nice explanation!!!
Thanks for advice .
helpful one, easpecially for an Asian. And now we have piping and tubing, are they different from pipe and tube?
I don’t understand why they have a second camera if he doesn’t turn to face it when it views him, he is supposed to be addressing us the viewers isn’t he?
Thx mate!
Detailed explanation. Thank you.
I too made vdo in same subject.
Schedule is a pressure rating, that is why schedule 80 is thicker on 10'' than it is on 2''. 3" schedule 80 pipe and 3 1/2'' .219 wall tube are so close in size that they can be butt welded. Tube has tighter tolerance on I.D and O.D dimensions and wall thickness than pipe does. If you go through enough steps on good pipe you can certify the pipe to be used a tube. If the pipe is for example a low grade of chrome moly a material cert could be performed, then wall thickness could be confirmed and finally the O.D. size could be checked to confirm it is within tolerance. If all that checked out you could now use the pipe as tube. This guy needs to learn what he is talking about before he makes videos!
Good video, if one of your stores needs a shear, ironworker or brake give a email. Thanks.
With that reggae beat i thought you were talking about a different kind of pipe mon!!
That made me LOL
Picture tube is on the TV. Tubes were also used inside radios. This guy is possibly a mechanic or plumber and not a TV, Radio repairman.
IT WOULD BE BETTER IF THERE ARE SOME MORE ILLUSTRATIONS OR PICTURES FOR THOSE TERMS EXPLANATIONS TO AVOID BEING CONFUSED.
Tube can also be used for fluid transfer what about swagelok tube
Your soup market sells metal?
Yeah, just the cans.
Im confused about capillary tube in which high pressure fluid travels. But that is not called pipe as this video saying.
EXCELLENT EXPLANATION.
If I found a piece in grandpas shop how would I be able to tell?
why do they shoot a side profile in some of the video!?kinda wierd
Usefull, thank you
HVAC copper pipe err tubing?
EddieVBlueIsland fuck o mighty I finally realized that there is a difference between the two, until you pointed out that there isn't. very clever Capt.Plumber! 😆
Quite interesting.
In Germany we have no difference wording.
Pipe = Rohr
Tube = Rohr
Actually we describe everything in exact terms.
Not just say "Rohr", but Rohr having specific inside diameter, outside diameter, diameter shape, length, material, texture, sharp or soft edges....and so on.
Mathias Dreßke so like the smoke going up the rohr used to be people. Is that correct ?
The measurements get weirder than inches and fractions?! You guys need to swap to the metric system.😄
What about superheated tubes?
Thanks.
Are pipes seamless
But why do they use tubes in industrial boilers?
Maybe for the same reason that your car motor is an engine.
Maybe for the same reason your cement driveway is concrete.
We learned here that tubes are structural - a strengthening component. I was surprised too, but here's an expert telling us it is so. I guess the industrial boiler will be structurally strong if it uses tubes. A refrigerator is also made very strong by its structural capillary tubing. Women are made strong by their fallopian tubing. The London Underground has never fallen down, unlike its infamous bridge. This is because it's a tube.
Obviously his driveway would be concrete. Cement is only part of the story........
Grateful Dude cement driveway you say never seen that before
pipe 12" diameter or larger now measures by the outside diameter.
Thanks for your useful explanation. Please help. If I want to have a steel column to support a balcony on it (above it), is it steel pipe or tube? Is it a solid or a hollowed one? PS: I will put it between (not right in the middle, but the 5.5m scale) two columns (made of cement, sand and corals) which are used to support the balcony on them. Please help (if you have the website, please kindly share it with me). Many thanks for your kind help.
That was super confusing. Why would tube have tighter tolerances when pipe is used under pressure?!? Wtf? And I work with steel…
Wow, this video does far more harm than good in regards to differentiating between pipe a tube. Might want to send this one to the scrapyard and try again. (By the way, I am very familiar with the differences between pipe and tube and found this video confusing and inaccurate).
Can you do a video so I can know what's right?
Pipe is the one use by POPEYE and tube is the one ''you'' use to watch videos
Thanks fam
Not so, spirally wound circular duct is a tube and it's diameter is inside, not outside.
The info about pipe size being measured by bored diameter is completely wrong. For instance, 3" schedule xxs pipe has a bore diameter of 2.300" while o.d. will always remain 3.5" 🤔 very false video
But the copper tubing I just bought is measured by inside diameter🤔🤷♂️.
A tube remains a tube until it is used for transporting a gas or liquid it then becomes a pipe, tubes and pipes are round box sections are square or rectangular, internal or external measurements do not determine whether it is pipe or tube.
You are clueless. Don't try to educated people in a subject you are clueless about. A tube does not become a pipe as soon as it transports a liquid or gas.The MAIN 4 or differences are ALL about how they are CLASSIFIED by SIZE, THICKNESS AND INTERNAL OR EXTERNAL MEASUREMENTS.Key words being classified and standards. Anyone with a basic understanding of pipes and tubes, or ASTM classifications and standards would know this.
@@JohnSmith-yq7gu You are Exactly correct. I work for Ercolina USA and we provide all of North america with Machines that bend Pipe and Tube. Bob You are completely wrong sir🤣
Is conduit pipe or tube
Corey Lambrecht Your more likely to get a dumb stare asking for technical sounding stuff!
Conduit just means it's meant to hold something inside of it so the definition for pipe fits better than tube which is for structural purposes, but to include conduit the definition in the video should add that it can be for other things besides liquid or gas, like wires.
What if I use EMT? Then again there's IMC.
According to Jackson it's tubing if you're using it to build something and pipe if you're using it to contain something.
the person who made this video needs to get the presenter to look into the camera, not across it. looking across the camera is very disconcerting to the viewer.
Difference between pipe and tube?
You can't smoke a tube!
madfatchickkilla
Not what your GF says...she smokes tube like it's half off at the dollar store.
This site should be YouPipe
Do ship to Australia 🇦🇺
Didn't think I wanted to know the difference between pipe and tube, there you go.
But then you would never learn anything? And YT would cease to exist!
My god turn off that terrible music 🤮🤢
This seems wrong. I measured 3/4 inch tubing and its 3/4 inch INSIDE DIAMETER. The outside is 7/8 inch.
Sounds like you're referring to copper pipe. The rules change.
electrical is different
Sir u didn't blink once in whole video
How do you know? Is it because you didn't blink watching the entire video? Pot calling out the kettle here...lol
reptile
you can see his tongue reach for an insect at 10:03
Pipe is pipe, and tube is tube.
Neat.
easiest difference, pipes have "i" in it while tubes don't
