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

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.

@tradestutor11914 жыл бұрын
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.

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
@tradestutor11912 жыл бұрын
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.

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

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. Thanks for watching and I'm glad you liked the video.

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
