This was a very clear explanation. Much better than my instructor at my plumbing apprenticeship class. I feel much more confident with our final exam coming up in a couple weeks.
If you are interested, then perhaps you might take a peek at the Handtuber Offset Calculator which can be used to quickly work out offset measurements for instrument and copper tubing.
The way I was taught, measure the center of both pipes ( or lines ) , times(X’s) that by 1.414 …. . Whatever that number is , get your take offs for each 45 degree angel . U have 2 , add both take offs together then minus (-) that number to the number u got from ur og center to center and 1.414. 💥
I use this everyday measuring up duct. For spiral long radius(1.5r) fittings. Here's an example with 6" round fittings. First I figure my straight aways on my 45s. For long radius fittings you add diameter + half diameter (6+3=9) Multiply 9 x 0.414=3.72 If the offset is 10" You multiple 10 x 1.414 = 14.14 Now subtract 3.72 x2 from the 14.14. So you take 14.14 -3.72-3.72=6.7" long piece in between 45s. You can also determine offset length by adding together offset plus the 2 straight aways on the other sides of the fittings. 10+3.72+3.72=17.44" Long offset.
Regarding comment from stonz52. Travel lines E, D, & C are each 11.31 in and the hypotenuses of a 45 degree triangle. Each 'travel' has a rise of 8 in and a run of 8 in. The vertical side of the triangles with hypotenuse D & C, is the same as triangle E. That height is 8 inches and is subtracted from the 40 inches for each lower pipe H, G, and F. (Try it with bendy straws.) I hope this helps & sorry for delay in responding.
Typically, if you are dealing with a 45 degree parallel offset, then the angles throughout are 45 degrees. However, you can have parallel offset of different angles and then, you need to deal with the rise and run of each angle.
Hi Crispy, here is a list of some math that you should look at before starting first year plumbing: Order of Operations; Fractions; Decimals & Percents; Imperial and Metric Measurements; Unit Conversion; Linear Measurement; Working With Formulas; Perimeter, Circumference, Area, & Volume; and Ratio and Proportion. I hope this helps.
i am only learning this shit because i am on my 3rd year of my plumbing apprenticeship... i have spent so many hours in the field and my dad is has his master plumbing license... never will you ever actually use any of this bs in the field. i ask for help and he looks at this and me like im insane for even asking.
lets be honest. im a plumber and have been for nearly 15 year. when in the real world do you have time with bending formulas. any good plumber can work off sets out with a straight edge and tape measure
jamboSAFC I'm a pipefitter apprentice and we are going over offsets in out schooling right now.. shit is way more complicated than actual site work.. like you said easier to just use and tape
I totally disagree ,what's easier doing a sum or getting ur tape and straight edge out setting it out drawing etc ,much easier to do the math,a foreman on a previous job,Mick RIP,would always go on about using calculations and he was so right esp when 6metres in the air and using larger pipe.
Travel of 8" is 11.31 " then what is remaining .31 ? You cannot apply that decimal .31 in actual measurement unless have to convert that decimal to fraction. And that is 5/16 so , total travel would be 11 5/16 ".
Why are you using .414 for A, B and E if you have a 45 angle and your spread is 4 or 6? If is 4 so 4 + 5 = 9 that's for A, if you have a 45 angle it's impossible that run or set changes, if E, D and G are the same length so still are a 45 angles

Pls why is tan 45 divided by 2 in looking for the difference in length. Tan is opposite divided by the adjacent...this should make the difference in length : Dil = 4 × tan 45 and not 4 × (tan45)/2. Please I stand corrected.
measure center to center of given offset ×1.414 add that into inches , then look at your pipe fittings and how much it offsets on both ends lets say you have 2 -4" 45°s thats a 2 inch offset × 2 which is 4. , - what you got from your centerline calculation of your two center points × 1.414 just saying this is in the field work when you can't sit and do math all day and have to get the job done , learn center lines on the fittings your using , they vary and you will be alright .
Dream Therapy exactly. Been in field can't sit down and work all this out. I'd like to know how to quickly do it work out my pipe and also would like to know the method of running more than one pipe equally spaced. Doing my head in working all this out
Sounds like you both need skilled craftsmen. Don’t forget to take off for gap. What is so difficult, gentlemen? Standard 6 to 8” spread. It’s simple math. You don’t have 45 seconds out of your day to do one simple math equation and effectively do your job?! You do realize this equation serves a purpose other than, “looks”? Reread your hydronic text. I’m guessing you sit in an office and bask from the glow of your college degree, however.. I need a 3 ton come along to rack a skid. Go find it. I want the blue one.
Just came across this video..Great video..I was never really good at math..but you made that quite simple..need more videos like this plumbing math..
This was a very clear explanation. Much better than my instructor at my plumbing apprenticeship class. I feel much more confident with our final exam coming up in a couple weeks.
thank you so much. best tutorial on this subject. sure you may not do this in the field but for a test on paper her explanation is golden.
Awesome video, best one I have seen on this. This Happens to be on the Tennessee state plumbing exam
Thank you. Great refresher! You did a great job.
thanks for the video for b breaking it down like u did I've seen other videos n got me confused!!
pipe fittings method good experience. all videos brilliant.
Absolutely great video, very very helpful!
Very clear explanation. Well done. Thank you ma'm!

Agree nest video Ie seen explaining Parallel offsets just awesome
This video was so helpful!!! Thank you!
awesome video was alot of help!
Bless you kind woman.
Very understandable...so clear..
Thank you so much! This helped quite a bit understanding outside the classroom.

What about fitting allowance???
I’m a licensed plumber. This was a good video. PlumberDad approves
I use this everyday measuring up duct. For spiral long radius(1.5r) fittings. Here's an example with 6" round fittings. First I figure my straight aways on my 45s. For long radius fittings you add diameter + half diameter (6+3=9)

Thanks maim god bless you
Great video
what a great explanation. thak you
do you have to minus the throat radius
nice vids i learn a lot more power and godbless tnx
so helpful thank you
How you calculate a rool offset
you can always screen shot the formula see if that works for you guys
Thank u so much this viedo really F-ingh work for me

Awesome. Thnx.
Than you
where can i find the Trigonometric function and constant chart that you are using? thank you
Dane Mcinis screan shot it
Thank you so much.
very nice
Thank you ms.
thanks:) more..
thank you
Nice vide
Why is the angle 22.5?
Tem como traduzir para português
What if the angles are not the same how will you get the degrees for different angles?
Typically, if you are dealing with a 45 degree parallel offset, then the angles throughout are 45 degrees. However, you can have parallel offset of different angles and then, you need to deal with the rise and run of each angle.
Does formulas and constants work along with metric?
of course ! This is pure trigonometry and does not depend on the units.
I’m starting an apprenticeship and I’m worried about my math skills. What do I need to study for first year plumbing?
Hi Crispy, here is a list of some math that you should look at before starting first year plumbing: Order of Operations; Fractions;
Decimals & Percents;
Imperial and Metric Measurements;

@@RRCWiseguys Hi teacher, pleaae how to make parallel for electrical trunking? Thanks you teacher.
i am only learning this shit because i am on my 3rd year of my plumbing apprenticeship... i have spent so many hours in the field and my dad is has his master plumbing license... never will you ever actually use any of this bs in the field.
i ask for help and he looks at this and me like im insane for even asking.
Good 👍
I need 90degree parallel tube formula
Using this ex for my Redseal exam
Do more 45 videos but with little detail. More difficult please
thank...😂😂😂
Plse lncentric reduser op load 10 cut

jamboSAFC I'm a pipefitter apprentice and we are going over offsets in out schooling right now.. shit is way more complicated than actual site work.. like you said easier to just use and tape
jamboSAFC lol she forgot to subtract the fitting allowances
Its only for testing journeymans! Welders as well! I agree with you absolutely
I totally disagree ,what's easier doing a sum or getting ur tape and straight edge out setting it out drawing etc ,much easier to do the math,a foreman on a previous job,Mick RIP,would always go on about using calculations and he was so right esp when 6metres in the air and using larger pipe.
Rat plumber

you have new on
Piping fitting
can you explain this example for 60 degree
6.66
Travel of 8" is 11.31 " then what is remaining .31 ? You cannot apply that decimal .31 in actual measurement unless have to convert that decimal to fraction.
And that is 5/16 so , total travel would be
11 5/16 ".
Why are you using .414 for A, B and E if you have a 45 angle and your spread is 4 or 6? If is 4 so 4 + 5 = 9 that's for A, if you have a 45 angle it's impossible that run or set changes, if E, D and G are the same length so still are a 45 angles

sir thanks for imformative.but iwant short method can you give me constant number of 15,30,45,according to ISO,
Pls why is tan 45 divided by 2 in looking for the difference in length. Tan is opposite divided by the adjacent...this should make the difference in length : Dil = 4 × tan 45 and not 4 × (tan45)/2. Please I stand corrected.
(A길이=5+3.31) (B길이5+3.31+3.31) tan 22.5*8= 3.31 왜 복잡하게 계산하지???
Incorrect
