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.

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.

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.

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.

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. 💥

@RRCWiseguys 5 жыл бұрын

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 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.

What if the angles are not the same how will you get the degrees for different angles?

@RRCWiseguys 9 жыл бұрын

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.

@jg1000ful 3 жыл бұрын

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

@renatoilagan5607 2 жыл бұрын

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 ".

@uchify 4 жыл бұрын

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 .

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.
