45 Degree Equal Spread Piping Offset for the construction trades.

Thank you for taking the time to make this educated video for trades. I'm a plumber who didn't understand this for the longest time, but i now fully understand. I work and run cast iron and nothing looks so nice when you make beautiful offsets.

Hi Patrick: I'm glad you liked it. I hope you've had a great Christmas season and have a great new year. Keep making those beautiful offsets!

Haciendo algo de trigonometria, obtuve la siguiente formula: Extension=spread x tan(@/2) Donde spread es la separación de centro a centro Y @ es el ángulo del offset, por eso si es 45 tan(45/2) es 0.414 Si es 30 tan(30/2) es 0.268

Thank you for providing these videos, currently completed level 2 pipefitting and will be taking 3 and 4 this spring. This is a good basic refresher.

[@dbj1007]

I enjoyed the training, but where is the formula 0.414 derived from? Okay, I looked back at the comments and found where you answered my question. What might be good to explain here is that the center point of the elbows are at 22.5 degrees, in relationship to each-other.

[@araujo41785]

Best explanation, thanks so much!!!!

[@samdeyton5449]

Can you share the formula for the 45* run lengths when doing a horizontal to vertical transition using 2x 45* fittings? The application would be to use this equal spread offset formula and also know the calculation for the 45* slope cuts of pipe when transitioning from horizontal to vertical. Thank you

[@iVETAnsolini]

This helped me understand 45 offsets in the simplest of ways. You should have added 2 more lines in there for more depth! But good information

[@tradestutor1191]

I'm glad it helped. Thanks for watching.

[@thatsSWAGGERY]

Do you still have to take off for the two 45 fittings?

[@Bri11ante]

What if its a 30 degree or any other degree? We're at a project where we're running (7) 4" inch rigid runs from a box, over to another box. We have a straight coming out of the box -a pre bent 90 - a 30 - a straight - a 30 - straight - 90 - then straight on the other end going into the conduit box. We're aiming for a 6" inch spread but all the measurements are off. The run from the 30 to the other 30 all the couplings are touching and closer together. We have all the straights coming out the box going to the 90, the same lengths. Thats where i think our issue starts.

[@jonnyz5758]

What is the formula for the rest of the other angles?

[@gillplbgandhtg1]

Spread times the tangent of half the angle is a better way to teach it because it covers all angles.

[@williamperezjr6942]

can you yell me how you came up with .414 I'd like to know how. thanks

[@tradestutor1191]

Hi William: 0.414 is a trigonometry number that is used when dealing with triangles with a 22.5 degree angle. Even though the fittings are 45 degrees there are 2 identical 22.5 angles created when the pipe turns. These two triangles are what form the trigonometry for the question. As it turns out the tangent of a 22.5 angle is 0.414 and this is the number we end up using in the formula. Although I didn't use trigonometry to sole the problem the number comes from trigonometry. Hope this helps and thanks for watching.

[@MrDjalma1966]

Great! If It is another angle?

[@eliseocantu9040]

Is the spread Center to Center? Or truly the distance between the pipe?

Would this work if my pipes are différent sizes?

Easy formula 1)Spread of pipe center to center 2)1/2 the tangent of your degree of offset 1/2 of degrees tangent X spread of pipe center to center

[@alexruiz1332]

hi when you say keep the pipes the same length after you find the extension do you mean the pipe with the extension or the pipe without the extension

[@agsojuan9532]

Awesome video, how would you do it if you have two 90 Degree elbows? Do you have a video

[@FreedomTrainn]

You simply measure your spread, then add it to your outside line to give you equal centers when turning the corner.

[@kallenorberg398]

thanks!! im going in to Oil and gas industry ¨tubing¨ and this helpt med alot!! but is it still spread x 0,414 if i wanna bend 30´degree?

[@h.m.5724]

It's 0.2679

[@dean8642]

Is your spread based off centers or the gap in between

[@tradestutor1191]

Hi DIY Doc: The spread is based off centers. Thanks for watching.

[@mauriciocampuzano6828]

Ive seen this method but they based their measurements off the ¢-¢ of the pipes and not the gap. Can doing this cause issues ?

[@tradestutor1191]

The measurement should be from center to center. That will be more accurate.

[@charlest4098]

Hi there can this be done in millimeters instead of inches? For eg 50mm x 0.414?? Cheers

[@tradestutor1191]

HI Charles: Yes, its the exact same number (0.414) regardless of the units you are using.

[@jimmycurtis5110]

Does the multiplier change based on size of conduit?

[@tradestutor1191]

Hi James: No. The multiplier remains the same regardless of size of pipe or conduit. Thanks for watching.

[@davesoutdooradventures5523]

no, the size of conduit is irrelevant, It's the angle of bend that is important. Different factors for differrent angles.

[@MrInfoPhilly]

How do you get the extension number. Say I want to do a 22.5 angle. Is the spread number the same, or how do you come up with the number

[@tradestutor1191]

Hello: The number for a 22.5 angle would be different. The number used in this video only works for a 45 degree.

[@MrDjalma1966]

Fits any angle?

[@aguyus8726]

Really liked your video but it falls a bit short in the complete picture of parallel offsets. As it only gives the example for 45° parallel offsets. That said I LOVE the quality of the video just wish you had gone more into the full formula to make people more versatile. This video is specifically only for a 45° bend. but if you wnet just wee bit more into the explanation of the formula this could have been all inclusive instruction. The formula for this is TANGENT ( 0.5 * Angle used) * Spread desired = Extension or in this case TAN(0.5 *45°) * 7" = 2.90" IF you use a different angle for example a 30° then the extension changes to 1.875" That formula, in that case, looks like this TAN(30° * 0.5) * 7" = 1.875" Make sure you are using Degrees and Not radians on your calculator

[@therealityoflife9060]

I'm confused we just did this in class for a 45 and they say to multiply by 1.414 and for 22 1/2 then we multiply by .414 , I read an explanation you gave to someone else that two 45 would be considered 22 1/2 degree but what if you had two 22 1/2 and you wanted to know the offset

[@tradestutor1191]

Hello: I'll try to answer that the best i can. When you have an equal spread offset using 45 degree fittings the change of direction (45 degree) ends up creating two identical triangles where it changes direction. As the change of direction is 45 degrees the two triangles formed each have a value of 22 1/2 degrees. We can use trigonometry to find the values in those triangles. The number 0.414 comes from trig and it defines the length of the opposite side of the triangle which has an identified angle of 22 1/2. That side is also known as the extension when it comes to equal spread offsets. The adjacent side is also known as the offset. In the end the extension is 0.414 times the length of the offset. I hope this helps and thanks for watching.

What is the factor one has to use if your bends are, say, 30 degrees? I assume it will be different than 0.414.

[@tradestutor1191]

Hi Hans: The only other angle we generally work with in the piping industry is a 22 1/2 degree and there are different numbers for that. This is all based on trigonometry so your best bet is to either find some trigonometry tables or use your calculator to find the correct numbers to work with. Thanks for watching

[@davesoutdooradventures5523]

.2679, it's a trigonometric function of the angle being bent

Thank you for the explication but why 0,414 and not 1,414? 1/sin 45 = 1.414

[@tradestutor1191]

Hi Todor: The trigonometry numbers come from dealing with a 22.5 degree angle. Although the fittings themselves are 45 degrees when the piece of pipe changes direction the numbers are based on the fact that it creates two 22.5 degree triangles. Therefore when you are using trig its based off of that. Its a bit confusing as you would think its based off of a 45 degree but its actually not.
