The take off of an eight inch pipe is 5 inches on a 45° elbow. Therefore you multiply that by two and u subtract that by the travel. That gives you the spool size. Also in pipe fitting dont forget to subtract your 1/8 gaps for the welding.
Yes ! 3.175 mm
8 is the diameter pipe. Take half of 8, then half of 4, then half of 2, which is 1. Take the 2nd and 4th number which equals 5. That's in inches. Convert to mm and you have 127mm. There are two sides so 127 times 2= 254mm. 707mm - 254mm = 453mm. Explaining how you get these answers helps people, otherwise they are stuck in confusion. The video helped, but there were things i had to figure on my own that you didn't point out. Thanks.
Pat Henry or just multiply 8 in. By 5/8 and u can get the same answer it's just a little simpler
is 90 degree elbow calculation is right can u elaborate.
So the 3500-3000 ELV he has is that in mm? Should I convert the ELV over to inches?
@@junaidkahnn69 no its wrong
Thank you for sharing
How about the welding gap why you dont .mention the gap it may be wrong or the spool must be longer,remember 3mm×2(both weld)must be result to failed of the spool computaions..just only asking sir..correct me if im wrong pls...
thank you Mr . Philipino .
Your Welcome!
Remember to factor in the 2 gaps (3.17mm X 2, typical) when calculating the pup length or you’re gonna have to shim the elevated run 😊😁
You should include the two welding gap from elbow to pipe,its 3 mm each gap,multiply by 2, from two joints. Best regards from aboitiz construction com. KAUBAN fitter.
Nalito rin ako.. ang alam ko kasi SPL=Tr-TO1-TO2-WG..
Just elevate the supports that are under the higher elevation run by 6.4mm & you will be fine or shim it by that amount 😃
exercise number 2 i think their is something wrong on your answer..
how it happen that 609.8mm (2ea 90 deg elbow) is longer than center to center with is only 500mm base on your given EL 2500 and EL 2000 and your cutting lengt is 109.6mm
45°LR is diameter of Pipe or size multiply by 15.875mm..
Is the elbows long radius or short radius?
Sir, is that mm? if so, I think there is something on the last one, 500 elevation is not enough for the two 90 degree elbow with 8 inches diameter, 609.6mm for both take off plus 109.6mm spool length equals 719.2 mm total length. correct me if i am wrong.
his maths showed the offset was to small by 109.6mm not the spool is 109.6 as he said
You are write.
Nice dami matututunan sir
your welcome
The difference in between the length, you have to divide 2 and cut each 90*, 54.8mm the center off the 90*
thank you sir. more power.
thank you
90 degree 2 elbow centre you need to minus from 500 (2500 minus 2000) is it right / you need at least 1000 mm difference if you need a spool piece in between then u get a spool piece bro
Ang twag sa spool na sinasabi mo ay cut piece or true length ng pipe. ang spool na tinatawag ay field weld to field weld na joint.
How is the takeout on an 8" inch pipe 15.8 for a 45 degree angle? Aren't you supposed to multiply 8"inches by .625 or 5/8?
its the same bro... for inches it is correct that 5/8 or .625 multiply by 8" pipe diameter.then multiply by 2 elbow. for milimeter or mm it is 15.8 mm multiply by 8" pipe multiply by 2 elbow. depends on what you are using. inches or mm
i think 8 inch pipe diameter to be ( ) first by 0.625 inch then ( ) it by 25.4 mm = 127 mm= take off of one 45 degree elbow. please check if i am wrong.
Exactly i was doing this in feet which would be 5 in per 45.
bcoz the TO is 600 & the length from center to center is 500.
bt anyway u r really doing a great job.. thanks for all the valuable videos ...
keep it up.
Thank you!
1.414 = sin 45x2=1.414
Where did he get 15.8 for 45
And 38.1 for 90
38.1 is the simplest way to get the take off of long radius elbow 90 degre. Ex. 38.1 multiply by the size of the elbow.
On 45 degree long radius. 15.8 multiply again to the size of the elbow.
That what it is
Welcome
Also, if the elevation from center to center is 500 on your two 90s, how is it that you only need 109.6 of pipe to tie the two pieces in? What happened to the the other 491? If a takeout for a 90 is 1.5 x Pipe Size... then the take out for an 8 inch pipe should be 12 right? And 24 if you add the other.... Are we doing a different computation here?
how could it be that the sum of the two take offs on example #2 be longer than the whole pipe itself? maybe next time you may consider including the units.
Long radius 90* equal diameter x 1,5 off diameter
Short radius 90* it’s equal diameter
Yes!
yes
Malinyn boss hindi mo binuwasan ng gap 6mm
the dimensions for 90° elbow are wrong...
how could be that possible ?
For accurate measurement and better solutions try downloading piping fabrication calculator-IPC 99 from google play store.
ha ha not all pipework is done in a mobile network location,, ie oil rigs so sometimes you need to know how to work things out youself
Thank you sir
Where did you get 1414?
Where did you get the 38.1 is it a formula?of 90 degrees?
1.5 inc X (diameter of pipe) X 25.4 = Take off
additional...u did not give what kind of elbow you've given???
For second 90deg is wrong
sory sir where does the number 1.414 come from
Furmula yan
Please tell me sir.
To find 45° spool you multiply 1.414
And to find 90° spool not multiply 1.414
Why sir please tell me
Ang Dame mung bassh pre...
Wla n kasing spool 2

Hey does this work on dairy sanitary pipe Aswell as schedule as sizes are different????
radical 2=1,414. 25,4+12,7=38,1
707 with welding gap
It's for you to decide how much measure of welding gap you want to put on
Wrong especially the second one doesn't even make sense. The length of the pipe to connect the two 90s is going to be less than the center to Center measurement. 109.6 seems a little short. I mean it's not going to be 1/5 of 500,
we cant put two 90 elbows in 500mm distance
.625??? for 45° elbow
you don't use welding gap???
Rex Amolato correct. He did not use welding gap. It is minimum 6 mm (from both side by 3 mm)
what is the 1.414
How do I know I'm multiply 1.141... how do I know ?
Only when you have 45° angles you multiply set or run by 1.414 to find travel
where is the gap b/w the pipe and elbow..so must subtract it to 3 mm gap
How did you get the elevation 3500 and 3000
Same question..
They’re random numbers used for demonstration purposes
Yan po elevation ay given sa drawing
Where did you get the 1.414
square root 2
Constant yan.
Hi im richard and i do topout plumbing and i always have a problem guarter inch per foot i know there is a pipe in a bathroom for a lavatory that needs a tee but you have to arm over 3 feet and stub out of the 2 by 4 wall with a 90 1" 1/2 pvc i know were the 90 elebow is measure back wards to get the slope correct
Quarter inch per foot
Can u call me 8326738393
Kailan po natin gagamiting ang 1.414???
Keep it simple go and buy a blue book please
x=500/sin45 x= 707
Brother last one is wrong.
Gd sir my question lng po ako kong ang elbow 45deg 6" ang raduis nya ay 690mm ano po yong tawag don long raduis or short raduis at ano gagamitin na formula don tanks sana masagot mo yan tanong ko tanks...
What is the take off of
90° short radius
45° short radius
1.5 / .625
Yung huling sulotion 500 ang height tpos takeoff eh...609.6 ng dalawang elbow...pag dinagdagan mo pa yan ng 109 lalabis na yan sa 500 na height!!!ipa revise mo sa engineer boss ang 500 dpat eh 3000-2000=1000 saka mo i minus ang dalawang takeoff ng elbow na 90 degree..para 1000-609.6=390.4 yan ang tubo!!!sala ang given mo boss!!!
Kung hinihinge nmn ang gap eh di i minus mo din...saka next time boss dpat my nkalagay kung ano klaseng elbow gamit mo kung short radius o long radius!!!dahil magkaiba po yan ng takeoff...pero dhil ang pagkuha mo ng takeoff eh 38.1 di it means long radius....😂😂😂 share lang
explain and why
Last one is wrong
Boss ..yun spool center to center 500...tapos yung take off dalawa 608..paano yan....
Mag fabricate ka nalang boss pag hndi pwd.. Kasi meron talagang mang yayari na mag kalapit Lang ang gap. Short 45 deg.
Hindi naba,i minos ang gap boss?
Second one cannot be.. should add more length to elv.
Mas mahaba pa yong dalawang take off kaysa length nang pipe center to center,.
I want to know how make offset of 300mm cable tray
Additional thikness for 8" pipe
He based it on the center of pipe. No thickness needed to be explained. He only show how to compute take off an how to get the pipe spool for 45 degree off set,run and travel.
for example 90 degree elbow how found take off
38.1D=TO 90ell
How come the 1.414 please explain. Thank u
Csquared equals 1.414 which is the square root of 2
Unclear.. where is that 1.414?
Off set x 1.414= travel- 2 45s centre = end to end travel pipe
How to find out the centre of a 4" 45 elbow,,,,4"" 2" 1" 1/2 = 2 + 1/2 = 21/2 centre of a 4" 45 elbow.
Do the say for all sizes this is the easy way
1.414 how to coming
Is a factor for 45 ells. You can use it every time when you have 45*ells
Run x1.414 or offset 1.414 you got the travel
sir hinde n po b inaalis ang gap?
How to know the elevation???
500mm=19.68in and 8in dia.X1.5=12in (take off). 24 in total take off from 19.68 inches doesn't make sense.
25.4×.625= 15.875
Where did you get the 1.414 and also what is that
sine 45 deg.
√2 = 1.4142
Unclear what is this 1.414
Where did you get the 15.8? Thanks
38.1
sir what formula do you use?
Sir ano ung 1.414
Esta mal el segundo de los codos de 90... Te faltó elevación
check again?
boss good day po, saan nkuha ang 1.414
Pythagorean theorem yan boss. Yang 1.414 ay ang formula panu kuhain ang sukat ng right angle at diagonal measurements ng 45 off set,run at travel. Sa high school Gina gamit na Yan natin. Di lang natin napansin. Theory Yan ni Pythagoras ng Greece.
where did get 1.414 and 15.8
you can use 1.414 for 45 deg. and 15.8 takeoff 45 deg. elbow
sorry i not understand 15.8 and 1.414
i know formula center elbow tg( &÷2)× 38.1×N
and tg (&)= 500÷x
x=500÷tg( 45°)
Same situation where from 1.414
cos & sin45=0.707 not 1.414
Lahat ng vedio mo pinapanuod ko imbes Sana makakuha kami ng idea Lalo mulang binubobo ang nanunuod sayo nakakahiya. Wag ka nalang Mag vedio Kong ganyan wala kang alam sa pipe fitter na trabaho. Masmalaki PA ang takeoff ng elbow kaysa total length.
Mali yong 45° nya.. hahah mas lalong lumaki ang spool
Para lng yan sa same 45° ang 1.414 formula
Anung size po nang 45degree na pittings
Can you please explain 15.8 and 1.414? Nakukuha yun iba pero di ko lang maintindihan 15.8 tsaka 1.414 kung saan mo nakuha. thanks..
for 45 deg el. 5/8 or 0.625"x25.4mm= 15.875mm ; travel=sqroot of runsqrd(1)+sqroot of setsqrd(1)=1.414
Teemo can you pls advise where did you take 0.625?
Jason Generoso 15.8 mm kung kukunin ang take off ng 45 degree. multiply by pipe diameter multiply by 2 elbow then ibabawas mo na sa center of elbow. ang 1.414 nmn ay ang squareroot
H
1÷sin(45)=1.414
You're leaving out a lot of info like where the hell does the 1.414 come from
Agree and where did u get the 15.8 it must be explain also
1.414 is a constant used when calculating the hypotenuse of a right angle triangle (1.414 X rise or run). It’s faster than calculating the square root of rise X rise + run X run (Pythagorean Theorem).
@@makenjiearkanghel7152: 15.8 = 5/8, he’s mixing Metric & SAE.

What do you call those dotted line?
Phantom lines, as listed I’m your IPT manual 😁😊
where did u get 15.8?
popop abarico 45digree elbow center is 15.8
This is incorrect
If it is an 8in 45 elbow
The take off is 5in
popop abarico the take off of an 8 in 45 ° elbow is 5 in. Idk where he is getting 15.8 from but that is incorrect
15.8 is the formula for 45 degree elbow. multiply to pipe size or diameter of pipe.then multiply by 2 because there are 2 elbow
the formula is pipesize x 5/8 ..15.8 is converted to metric 25.4. 1 inch, so 25.4 x 5/8 =15.875
👍👍👍👑👑👑👏👏👏
Where did the 38.1 come from???
He’s mixing metric & SAE in his calculations; 38.1mm = 1.5”. Therefore the centreline calculation of a 90 degree, long radius elbow is: fitting diameter X 1.5 (8” dia. X 1.5 = 12”) OR. (203.2mm/8”” X 1.5 = 304.8mm/12”.
I’m a Canadian Pipefitter & I use both systems on various job sites but I don’t mix them up like this. It’s always one system or the other, usually SAE but it’s easier to calculate the whole numbers for spool lengths in the metric system as opposed to fractions in the SAE (imperial) system. It can get really screwy if I start mixing & converting.
I hope that this helps.
1,5 x 25,4 = 38.1
How u got the value 1.414. Please explain
