So what would the final pup piece be?? The reason I am asking is because since there are 42 degrees and not the average 45 degree than the formula 1.414 would be out and another formula would have to be put in to take off both 42 degrees fittings right!??
Unreal! I struggled in school with rolling offsets for quite a bit... This is by far the clearest representation I have seen within 3 minutes, nothing like some good ol' "in the box" thinking!
Dude,you explained this very well & the visual presentation was good.Can you explain how to fab eccentric reducers,figure out the centerline,thks! Great video!
I have a quick question. Do you have any formal pipefitting training? Why do I ask.. I’m actually a teacher at our local union. Sometimes pipefitting channels come up on my feed and I have to have a look. Most I laugh at. I did come across a couple “Smart Azz” Guys about 15 years ago. I gave them a problem to work out and they still have yet to give me the correct answer. You have a genuine interest in pipefitting. Keep up the good work!
No formal training in pipe specific type work., just worked in fab for many decades and with some ace hands who I learned a bit from also. Worked with some great guys in precision sheet metal holding very tight tolerances through multiple bends and how to get the correct flat patterns for complex things like rectangle to round offset transitions. Had a little formal training with drawings and math as it applied to precision sheet metal but mostly just doing it a long time and trying to help out the other guys with layout.
@@offthehookdesignandfabdotc2582 That’s Great! Keep doing what your doing and never be afraid to learn new things! 🤙🤙😎. I spent my whole career as a pipefitter. 25 years in a paper mill and 15 years building engineering spaces in new cargo ships. Big boilers and SuperSized Superchargers. Did you ever see a supercharger with a 72” diameter inlet! 🤣🤣
Good video. I would explain though that 8" would be your center to center, 4" is your vertical distance between the pipes and 6" is your face to face. Good refresher 👍
I had to do a rolling offset in the field for the first time and came across this video and it helped me out tons. Thank you so much for the help. and by the way I love the giant gun on your welding truck what is it used for?
How your travel length is 10.770 and the degree of your fitting is 42 degrees.. if your fabing it up before they dig the ditch how you you know how much to roll your fittings left turn or right turn
But my question is how can you use a formula for a 30° angle, and then type a few numbers into a calculator to figure out your angle. Shouldn’t you have to use the formula to find an unknown angle, and wouldn’t that cancel out your A squared plus B squared equals C squared
With trigonometry you only need two bits of information to find the third unknown. So if you know the length of 2 sides you can find any angle measurement. Or if you know the length of one side and the degree measurement of any angle then you can find the length of any of other sides.
Also, trigonometric functions work for right triangles only. A right triangle has one 90 degree angle, always. So if you know the other angle is 30 degrees. Then you know the third angle is 60 degrees. All triangles only have 180 degrees.
The 1.414 is a shortcut to finding the length of the long leg of a triangle but this short cut of 1.414 only works with right triangles with equal legs and 45 degree corners.
If you listen to the beginning of the video I said this was for figuring out the center to center distance. The elbow take off will of course have to be subtracted. That is a given.
@@offthehookdesignandfabdotc2582 I missed that part. Loved the presentation! 👍👍. It was nice to see someone getting off the 45* kick. Pipefitting is not always 45’s, tees and 90’s.
An offset is when the pipe moves in one direction in the same plane to avoid an object or make a tie in. Using his box presentation imagine the box is a room and a pipe is running through this room. On one side of the room it enters near the floor and travels along the wall through the room. On the other side of the room the pipe needs to be at a higher elevation because let's say there is a door frame in the other wall. A regular offset the pipe would change direction at an angle upwards with one elbow, then change direction again to be horizontal with the second elbow. The pipe is now at a higher elevation to go over the door and through the wall, but the pipe is still running alongside that same wall. It only changed direction in one plane, changing it's elevation.. Now imagine that same pipe coming through the room and changing elevation to avoid the door and exit the room at the other side, but now there is a steel column or something in the way. Now the pipe will have to change direction upwards to a new elevation, but also have to move to the side or "roll" away from the wall to avoid the obstruction. This is a "rolling offset". So to answer what I think you're asking, rolling a offset is a "two way" offset, the pipe is moving on two different planes during the offset. There is no such thing as a "2 way rolling offset".
Best visual representation to teach someone a rolling offset layout i have ever seen. Gonna remember to use that when I'm trying to teach someone else

@@PedroLopez-tj9qt the degree of the offset is still 45 degrees. The degree of the roll is not.
@@chimera91977 thank you sir!!!
All of us rig welders appreciate your content respect to your knowledge and time to put it out there for us hope you get more subs !
Please make more videos when you have time. I learned more in 3 then I have a in a while . Thanks very much.
The box example is the best way to show it works rooling offset calculation... THANK YOU FOR YOUR THIS GREAT VIDEO!

it was one the best practical trainings for pipe line welders, thank you very much
Great vid, I’m been pipe welding nearly 10 years, I’ve never had to do a non 45 degree rolling offset, I’ve done plenty of rolling offsets with 45s.
You get a lot of odd angle rolling offsets when the bending
Dude,you explained this very well & the visual presentation was good.Can you explain how to fab eccentric reducers,figure out the centerline,thks! Great video!
Great content so far some of the best videos simple yet effective thanks for your help
This is first video ive ever seen to make it actually click in my fucked up brain. Much appreciated
Great way of explaining!!! The box visual is perfect!!
I’m learning how to fit and your video made it very simple to understand, ty D
Great explanation and teaching tools! Awesome video all around thank you!

J RAY its a BBQ and smoke rolls out the barrel. The cylinder area is split and hinged thats the cooking area.
Awsome description 👌
Great video
I have to apologize to my math teachers who taught me this when I was young and thought I would never use this stuff.
Man. Thank you.
Excellent advice
Ok sir you everything explain very good. But one thing you not explain. elbow rolling degree will how much please please please you explain us.
You can also go a²+b²+c²=rolling offset length² if you know all 3 initially
The easiest way is to measure it out on a square. Very simple and easy
Very good info for pipefitter like me thank you sir ,may I ask what booklet you are using sir? Thanks..
The book was the manual for the pipe trades pro calculator.
Hell ya 🤘🏼

How do you get the measurements though if theres nothing good for a point of reference, like if it was on dirt with nothing very close by
How to calculate angle horizontal positron? That is st I'm wondering for a long long time
How would you find the other legs mesurmeants in the real world ? Pulling strings or what ?
Who is the autor of pipe fitter book ?
🔥🔥🔥
Se ve interesante pero no dominó muy bien el idioma,podrías traducirlos gracias,saludos desde España...
I thought the next step after you have the 7.211 was to multiply by 1.414 can help with my question
The 1.414 is a shortcut to finding the length of the long leg of a triangle but this short cut of 1.414 only works with right triangles with equal legs and 45 degree corners.
Thank you very much for answering
If you do multiply the 7.211 by 1.414 you will avoid having to use mitered fittings. It will work with 45s no problem. Think about it!
What is the app u talked about
miss the rolling elbow grade???
You missed the takeout for the elbows.
If you listen to the beginning of the video I said this was for figuring out the center to center distance.
The elbow take off will of course have to be subtracted.
That is a given.
@@offthehookdesignandfabdotc2582 I missed that part. Loved the presentation! 👍👍. It was nice to see someone getting off the 45* kick. Pipefitting is not always 45’s, tees and 90’s.
@@RichGT350r true. I made some other videos for figuring out the take off and other things. Tried to keep it simple and separated.
So would both fittings be a 42 degree?
Yes
So this is different than just a rolling offset right? It’s a 2 way rolling offset
No its just a rolling offset explained 2 ways
An offset is when the pipe moves in one direction in the same plane to avoid an object or make a tie in. Using his box presentation imagine the box is a room and a pipe is running through this room. On one side of the room it enters near the floor and travels along the wall through the room. On the other side of the room the pipe needs to be at a higher elevation because let's say there is a door frame in the other wall. A regular offset the pipe would change direction at an angle upwards with one elbow, then change direction again to be horizontal with the second elbow. The pipe is now at a higher elevation to go over the door and through the wall, but the pipe is still running alongside that same wall. It only changed direction in one plane, changing it's elevation.. Now imagine that same pipe coming through the room and changing elevation to avoid the door and exit the room at the other side, but now there is a steel column or something in the way. Now the pipe will have to change direction upwards to a new elevation, but also have to move to the side or "roll" away from the wall to avoid the obstruction. This is a "rolling offset". So to answer what I think you're asking, rolling a offset is a "two way" offset, the pipe is moving on two different planes during the offset. There is no such thing as a "2 way rolling offset".
@@chimera91977 Awesome thank you for that explanation👍👍
What's up with that big ass gun looking thang? That's on the back of the 🚚 you were working on? 😅😂🤣
Its a BBQ. Cook a steak and smoke rolls out the barrel.
are you sure this is rigth buddy what your saying
Should be but you need to subtract the takeoffs for the elbows.
This is 2 ways to double check so double check.
dont you ever do laundry
Not very often, too busy welding.
Gees don't be job scared dude
This is basic ass math
