- in this episode we are going to go into some very basic pipefiter takeoffs. now fro all of you wanting to get into the pipewelding trade this is going to be extremely important for you to understand and be able to implement in the field. Lets get right into it a basic explaination of a pipe take off is the overal length og a piece center to center minus the fittings. you can not forget to take out fittings possibly gaskets and weld gaps depending on how perfect this piece needed to be. hope you enjoy the video as we go into some basic pipefitting knowledge. everyone be blessed.

For some reason to me, a 40 yr old woman who has never done any type of this work, makes perfect sense! Maybe I should be a pipe fitter, lol. All it takes is a great teacher. Thank you, sir. Makes total sense.
Man you are kicking ass for only being 26. Mad props and thanks for the lessons.
Thanks man. That video was a little bit ago. I’m 28 now almost 29. Thanks again
This is the most comprehensive video I’ve watched on this topic so far thank you so much
hopefully it helped and continues to help a bunch of guys out.
Hi Jacob, Im an old time pipe fitter and its good to see some one like yourself teaching pipe on youtube. Good job.
Couldn't have put it more simpler than that. Now I'm not so confused keep up with the video's. It really helped me understand what I'm getting myself into
Thank you so much for your tutorial. I will be building my first drain line tomorrow. I'm going to accomplish blacksmith fabricator welder but I am new to the pipe game. I'm so mother f****** excited thanks again buddy for your tutelage.
So glad I found this I start Monday and I've never done anything like this... Lots of construction but never pipefitting... Thanks for helping me not look like a dummy 😂
How did it go Jamie?
We’re just going to paint a nice tree over here. There are no mistakes only happy accidents. Maybe that tree has a friend or two, you decide...Oh... that’s refreshing. Lol Bob Ross, gotta love him.
this is killer info but always measure your fittings at flanges first because ive had them not be true from the factory
Jacob, as you know, ISO stands for Isometric Drawing representing what a 4-dimentional object will look like when finished and the only way to show that is by plotting out it's 4--dimensional shape on the 2-dimentional surface of the plans sheet. Back in the early 1970s one of the jobs I had in the Air Force was that of a Draftsman and I've drawn every type of ISO that you can think of. Until a person who is new to construction can look at that ISO and "see" that finished object, they will be lost on that job. Unless a welders helper can "see" what that finished pipe run will look like when done, then all of the instruction that you give them in doing take-offs won't amount to a hill of beans. You say that the math is where you have a little difficulty, just imagine how hard your job would be if you could not see how that pipe structure will look like when done. No matter if it's 2 pipe runs coming together from different angles or an entire structure inside of a processing plant. Once the "newbie" can do that, then he's ready to learn the more technical things such as doing those take-offs and you are just the guy to teach them if they are lucky enough to have YOU as their welder.
Not 4 D,....you have to be drawing in 3D ~
@@buddydog1956 You are correct. My bad. The 4th dimension is TIME. Guess I didn't take the time to review what I wrote. LOLOLOL.
I respect what you are doing bro. It’s a great thing to teach any helper interested in learning our trade. I have been fitting for over 22 years and I’m here to tell you that there aren’t many guys coming into the business that are smart enough(no offense guys)(we need good welders too) to be a fitter. Lol.
Melvin Whitmire Well you do realize when you become a pipefitter you have to do 4 year or 5 year apprenticeship so it’s your job to teach the young people how to do it so it’s not their fault if you don’t teach them right not saying you in general though
Chico’s pipe fitter pocket cards are very useful for take offs also! Great video!! 👍🏻👍🏻👍🏻
Love the video !!! What a awesome way to start the weekend by learning something like this. Thank you!!!!
I noticed on the video where you were talking while your wife was asleep you sounded really calm and relaxing and toned down
hahaha lol i also had the camera right next to me. I worry that you cant hear what im saaying but that one turned out pretty good.
dam these videos are alot better than the pipefitting classes I took in college.
I wish CZcams would come up with a double thumbs up button. I’m mean, hell, I’ve got 2 thumbs. I’d wear that thing out on your videos. Always useful info.
Two thumbs up sir 👍🏿👍🏿. You described how to do this very easily step by step and made it very easy to understand. Continue to be blessed sir!!!
Heck yea man keep those videos coming thanks for everything jake.
Thanks a lot for this video! Glad you take the time to help others out.
Pipe Trades Pro is another REALLY good pipe welders calculator.
songer121 Yup
Thank you!
One thing you can alway go to on the mark for your take off on some things is to cut at the back side of your line on your wrap around. Instead of taking off for your fitting or welders gap, remember that most blades, whether it be a matabo, bandsaw, or any other cutting utensil usually take off 1/8 of an inch regardless, should be compensated by cutting at the backside of the weld
It’s a really good video and you are right when it comes to fabrication but when coming to a written test it would be wrong because on pipe testing they don’t do the space gaps just what the iso instructs and also heads up on takeoffs for 90 degree elbows make sure if you are doing a SHORT OR LONG RADIOS. Really good videos man keep up the awesome work your doing helping new hands coming in the trade.
Love this type of video. I’m just starting out in fitting pipe
Perfctly good explanation on those takeoffs thank you for the class brother it comes in handy for anything keep on welding brother and be safe
Thank you for the video. I appreciate you.
Thanks for this video is helping me allot. Appreciate your knowledge brother. 😊
Inspiring video, brother. It takes a man to admit when they make mistakes and then share with others so we don't.
Thank you I needed to know this!!
Bro u just made it so easy! Thank you !
Thanks a bunch bud. Awesome vid.
This is a great video! I’m a pipe fitter helper and trying to learn how to read the prints. Please make more videos like this!!! Thanks I’m definitely subscribed
Muy bien explicado, mas claro que el agua!
Great information. Thank you
thank you so much , I looked for long time to understand the take off.
Hello....its my first ever subscribe for any channel on Youtubr for any category...though i am not into any of the trades but watching u explain the take offs and all that stuff is amazing...u not only a good tradesman but a fantastic teacher....keep it up and i hope one day i will learn every thing about pipefitting by just watching ur videos
Thank you for sharing awesome explanation
Thank you I learned something.
Great
Well done Jacob!!!
Thank you for this video.
Enjoy the series, thank ya sir
Your doing great brother!!!
Well explained and simple.
You're so sweet. Thank you for this awesome video!
This is a great example of field fitting fabrication, shop fitting is slightly different, the ISO's you'll receive in a shop engineering has already accounted for gaskets so the fitters don't have to, also in a shop you rarely stick weld so the fitter needs to account for weld gap for either TIG or MIG welding, otherwise nice job.
This was very helpful and inlighting. You videos and weldtube helped me out through out my welding program now im about to graduate and i have my eyes set on boilermaker Union. Just wantes to say thanks.
Your very welcome brother congrats on finishing
You Rock Buddy thanks 💯
This helped me 100% post some more plz
Great explanation
Great video.
It did help out quite a bit. Thank you broham.
no 5
Good stuff right here.
GREAT INFO.
Great explanation! Please consider doing take offs and makeup for thrheaded malleable pipe, and finding fitting measurements.
Hey thanks for the great videos, I’m currently going through college courses to get certificates for welding and I love learning as much as I can about the pipeline process because it would be a dream job. It really helps out to see your informational videos and you also shine a light on how important it is to be a welder helper to learn the ins and outs and get a strong footing of what welding is. With out a doubt will gladly be a helper before I even consider welding first just by watching your videos and knowing how much there is to learn that a class can’t teach. Keep up the great videos
Nice demonstration Jake. I will mention though, that weld gap will disappear when the weld cools. Doesn’t matter if you like a 1/16” or 3/16” gap. And also, long radius “LR” is the actual name of what most people probably think of as “standard” or normal elbows. 3R or 3D is what most people on a pipeline are actually talking about when they say “long radius”. I’ve only ever seen actual short radius elbows used in a refinery a couple times, where there was simply no room for a normal elbow.
very true very true. the short radius is what we mostly use also.
In general mechanical engineers stay away from short radius nineties, to avoid excessive wear in the heel of the 90 and to preserve the pressure loss caused from a sharp turn.
Great video! I’ve helped teach FFA Ag Mechanics team in past and I’m a sorry son of a gun because I’ll make them put away calculators and get the paper and pencil out. Great to use calculator but if it gets smashed your SOL. If have time keep the mind sharp and also pencil and soapstone. Can’t wait till you get to chapter on rolling offset. That turns me upside down!
Have a great weekend. Thanks for sharing your knowledge and experience!!!
Danny Harvey Danny I did a rolling offset don’t know if you saw that yet.
Please do more of these. I need to knock the rust off.
Thank You
Good explanation 👍
Great video Jake little known thing about Bob Ross is he was in the military special forces have a great night be safe.
You missed a 1/8" take off on one of the 90's!! Keep up the good vids!!
Good job brother
Sooo good! do more of these! Can you do one with a 20 degree rise on one of the pipes? Your a great teacher!
If you roll a offset the best way to figure length of pipe is measure it on a square. If using only 90’s then just account for fittings and weld gap. If you use 45s there is one extra step. After measuring on a square multiply by 1.414 then account for fittings and gap. If you are doing a basterd angle and cut a odd fitting angle from a 90.You need to figure out take off. The way you do that is use the trig tables in the blue book. You would use the formula tangent of a half degree of turn times the radius.
Oh my god
I just want to be the pipe welder not the fitter😂
Very nice video!
Thank you very much.
Hey jake can you also do a video on finding the two hole pin for a flange also hot to do miter cuts
Awesome video. So on site you get a set of prints, with what kind of fittings ( long or short radius and flange size/style)? And for every spool piece you do, you do all your calculations to get your own measurements and just start cutting you pipe and go to town?
So we all should buy that app
Hi, Interesting video. I have a question, how do you set up the flanges on either end of the pipe section so that when it comes to fitting the pipe the whole section matches up on the flanges for the bolts to fit perfectly?
Two hole pins.
I could be wrong, but when you calculated the length, you took off for 3 weld gaps, when I think you should've only taken off for twp. As far as I'm tracking, you shouldn't have that third weld on the bottom left connecting to the flange, unless you had a reducer coming off your flange, that I missed in the video
Good video brother
Thanks a lot
you bet hope it helped
Greetings from Alberta Canada. Do you guys down there call fittings by ANSI rating or pound?
Is GFL pipe fitting work inside or outside or both ,
What other jobs are there in pipe fitting/steamfitting my uncle does this thing called detailng he draws up blueprints of where pipe has to get layed out i just wanted to know what that is (detailing)
Any more fitter videos will be appreciated
Sounds good steve that helps me a lot.
A free app that you can download that shows all of the fitting dimensions for welded steel pipe is “The Weldbend Field Reference Digital Companion”. Just subtract your fitting take-ups and your weld gaps and your good to go... Check it out!
for sure thanks Robert hopefully everyone sees this.
Thanks for sharing buddy 👍
Great video! Explained very well. How do you figure in you bevels and cuts?
This was precisely about the cuts.....
As far as bevels, the measurement was from landing to landing. The beveled angle will not affect the measurement u less u cut into the face of the landing while beveling.
So in simpler terms, do the math in the video, then bevel it.
Did o answer ur q?
When beveling do you subtract the distance of the top of the bevel to the bottom of the bevel?
Nathaniel Byerly
Lol. Not exactly. End to end on pipe and typically center to end on fittings like 90’s and face of flange to end on flanges. And as he says center line of pipe to center line of pipe.
90’s (long radius/standard) takes out 1 & 1/2 the size of the 90. 6” takes out 9”. 4” takes out 6” and so on. This is for 90’s over 2” (weld fittings)
What you know about transition bevels... also autocad operators...
Greetings from Italy.good explanation.could you make a video about how to calculate when you have two pipes not on the same axe and maybe connected by two 45° and another piece of pipe?
Thanks
Use your take aways but to find your diagonal length you multiply 1.414.
Hi Jake , I'm just learning in how to deduct the flanges , gaskets and 3/16 " where we're going to weld and it came exactly
to your measurement 2 ' 5 9/16 " so isn't the measurement that goes on the " A " supposed to be 1' 6 7/16 " give the total of 4 ft. ?
SORRY I JUST WANT TO MAKE SURE ...
im a fitter you a fitter or welder... man thanks for sharing... im passionate about fitting
Joe Im a welder first but for what I do I do get a Fitter I wish I did because I would be learning a ton but this is all thig ive learned from old time welder and fitters thn applied them myself. we are required to take our own measurmants and weld.
Can you do a video about fitting to centerline on some pipe
is there a book available that has a bunch of pipefitting scenarios/problems and shows how to solve the problems?
Hay you should do a video on off sets where you have to multiply 1.414
Kalan Willoughby the square root of 2
That intro lmao Gotta love the haircuts 😂
Great videos, how about rolling offsets
Hey jake this is a bit off topic and i know you've shown your roll out wheel before but can you do an in depth video on yours ? I want to build my own and I want it to run true, does yours have a 6" chuck or an 8"? Thanks a lot for the awesome videos.
Chris I need to do a whole build on how acuualy get one laid out and built.
Good shit
Should go into the take offs on 90s and 45s
for sure brother we will do that.
How do you know on the iso the difference between a change in elevation and a regular 90° turn to the left or right? Also does elevation on the iso go vert up for elevation up and vert down for the elevation going down? I hope my questions make sense lol
great thought Dylan I wrote that down so I could do a video on it.
@@JacobSchofield right on man did u ever see my email with the pictures I sent of my machine? I restored it fresh paint and some new parts getting ready to be a pipeliner. Now I'm just practicing my downhill game
What is the “take-up” of a 4’’ long radius sch. 40 steel butt weld 90 degree ell??? Explanation please
On a long radius 90 One and a half times the diameter of the pipe. 6" is the take off for your 4" LR 90. A short radius 90 takes off the same as of of pipe. Example... 4" SR 90 take off is 4". This is the general rule. I hope it's helpful.
@@chrisjohnson9329 driving now however ima check it out in few video would be nice
Do u consider the shrinckage off the weldings...when you have a lot off welds this counts...sometimes i dont consider the gaskets takeoff to compensate for the shrinckage...
I dont normaly.
ok i ve learned that each weld gap shrincks half the size off the gap .....so maybe try to check if the final measure differs by more or less the size off half the weld gaps...then you know...i would like to see a video about that...is a small diference...but makes us feel rigourous....thanks again...keep up the good work...
👍👍👍👌👌👌
Hey Jake, how much leeway do you have with these kinds of builds? Say the over all length is 48", is there a +/- 1/16, 1/8 etc.? And say you are making this section and another crew is making the section that attaches to the bottom flange and another crew builds for the upper right section. If all 3 crews allow for the gaskets, this will be short at least 1/4". Or 3/16" if you factor in you only allowed 1/16 for 3 of the 4 welds on pup "A". Or is one crew responsible for the whole run? Thanks for another insightful and educational video! Peace.
very true Patrick. I dont really know all I can do is build for my pieces the very best I can do and hopefully they do the same and everything fits. I know for the stuff I am doing right now is two hard spots and then i just have to pull for the measurments to catch those points.
Hey Jake, please forgive my ignorance to your job and proceedures! Are you saying these runs are more of a custom build than a "production" type situation? For instance, if you have 5 or 6 of the same runs going into some central location like a manifold, you don't build all the sections and give them to 'installers'? Instead, you build each run to a certain point and start the second, third, etc.?
Thanks for your reply's, I know your busy and I really appreciate it! I think what you guys do out there is very cool and you teaching us what the job entails is terrific! All too often, we don't get to know if a job is for us until we try it. That can sometimes feel like a waste of time and money. But you have gone very deep into the job and lifestyle and I think I speak for many when I say "Thanks!"
Seems like you didn't account for the upper "pipe"? What are you doing, welding that top 90 directly to the flange?
What is the “take-up” of a 4’’ long radius sch. 40 steel butt weld 90 degree ell??? Please explain
I need help understanding the take offs for 90s. I haven't grasped the idea yet. I understand flange take offs but I get lost with the 90s.
A typical long radius 90° takes off 1½ times the pipe diameter. So a 4" 90° would be a 6" take off. Or a 6" 90° would be a 9" take off.
