Calculating a 22 1/2 degree offset piping system

This video goes through calculating the travel, offset and advance in a 22 1/2 degree offset.

What he didn’t explain here is that if you have a calculator with sine and cosine on it you don’t have to remember any constants. For travel of advance you want secant of angle which 1/sin of angle Ex. 1/(sin of 22.5) = 2.613. For travel of offset you want cosecant of angle which is 1/cos of angle Ex. 1/(cos of 22.5) = 1.082. This works for any degree offset like for a 45 degree offset your advance and offset will be the same so you can use secant or cosecant therefore 1/(sin 45) or 1/(cos 45) will both = 1.414. Have the travel and want the advance or offset? Well it’s sin of angle or cos of angle. Sin 45 = .707 1.414 is the square root of 2. Remember a^2 + b^2 = c^2 for right angle triangle, so if you use a unit circle where radius =1 (I know you’re asking what does a circle have to do with a right triangle? Just trust me) you’ll have 1^2 + 1^2 = c^2 therefore 1 + 1 = sq root of 2. Sq root of 2 = 1.414. It’s all trigonometry revolving around the unit circle. hope this helps someone because i just finally made sense of this while studying for city plumbers. They should’ve shown us in high school what these things were used for them maybe I would’ve paid attention in trig class anyway no point memorizing constants when you can calculate for any angle.

I love the fact that you don't have an intro. I have no patience for them.

Explaining the run and travel and the advance

[fearlessman]

Easy to understand keep making more videos.

[manasvinistrategic]

Easy to understand simple language, thnx

What's the Take off for a 22 1/2 degree fitting?

[epadrigo]

In pipe fitting or plumbing terminology, it should set, run and travel sides of the right triangle

[mosesmwanzia]

Thanks ist from the bottom and top of the pipes?

If the two 22.5° offsets make a 45° left/right (rather than parallel), does this approach still suffice?

[luckyhitswertres]

How do we know that the constant # we need to use for this degree is 2.61?woud you pls explain and teach us what we are going to use constant number in different kinds of degrees..

[regidormoya]

hello, can you please give 22.5 degrees Elbow Takeoff/formula.= like 45degrees elbow=1.414 .thank you

[rzz]

Why not use a 30 degree, if offset is 4”, i.e., obstruction . X’s 2 = 8 . If 1st mark on conduit is 8” . Add 8”, 2 mark is at 16”. Bend pipe first mark to 30degrees., flip pipe 180. Bend 2nd mark 30 degrees. Job done. We want to get paid, guiseppe. U think the boss want a trig. Major to bend pipe?

[hector]

Where do you get the the 1.08? and how do I find the right number for all angles. Like I know 45° is 1.1414

[paulocanoy]

Is 2.61 and 1.08 are the numbers that we can use in any offset except in 45degree?

[thomasgrundvig]

Can 2.61 be used in metric calculation? Are 2.61 a constant by inches?

[danfdz]

Thanks for these wonderful videos, , what if, I need to convert or work these out in millimetres please email me the formula Thanks

[tonycarmen]

wala bang constant number to get 22. degree spool

A little tip for your viewers, at the end of your video measurement was 14.18 inches. The .18 represents 3/16 For every .06 = 1/16. 16x.06 =96 or 1 inch hope this helps. Retired Steamfitter

I was watching this to help brush up on my 45°s for my ductboard trunkline. I always knew it was around x3 thanks for that number.
