For 90 degree fittings divide the diameter by 2 then add quotion to original diameter

for 45 degree fittings multiply .625 X the diameter on 3r 45's multiply .625X diameter then X 2

The take off formula of a 45 degree elbow pipe, will depend on what the pipe is on. Sometimes a 45 degree pipe will need a 90 degree right angle turn to come off.

measure the length of the fitting first. Then insert pipe into fitting and mark a line on pipe. measure that bit of pipe. deduct off the length of fitting and half it to give you your x dimension

There is no one formula for fitting take offs. The general rule used for gal and black malleable fittings is on a center to center measurement to take off the ID of the pipe you are using on each end of the pipe. Example if center to center measurement is 10 feet between a 1 inch tee and a 1 inch 90 ell. The end to end measurement would be minus 2 inches for a total of 9 foot 10 inches. If you are a industrial pipe fitter there is a pipe fitters blue book that covers all this and a lot more,but the formula we use is take the size of the fitting and break it down 4 times add the second and forth dimension together and there's your take off,ex. 10 inch 45 degree carbon steel would be like this,,,,,10-5- 2.5-11/4=6 1/4 take out.......

Depends on the stove, but usually not

Fitting take off is looking at plans and seeing how many valves ,tees ,and other fittings are needed for the proper installation

A broken PVC pipe that is glued to a metal fitting might be removed by applying heat to the PVC pipe. Heat should not be from an open flame, but a heat gun to prevent fire from the glue burning.

If that's where the freezing occurred and the compression fitting wasn't tight enough.

Where a single pipe tees off into 2 or 3 other pipes, like a Y fitting, a T fitting or a Double T or a Double Y

Take Off's are meant for what is the take off of a 10'' 90.that would be 15''.a standard long radius 90 will be one and half times the diameter of the pipe.8'' would be 12''a short radius fitting would be different.the system this is it= works well.

Use a pair of plyers and two small pieces of cork to grab the threaded pipe while you rotate the female fitting. Also, if you don't need the threaded piece anymore, you can use a whole cork inserted into the threaded pipe with a bit of apoxy or super glue.

The take-off for a standard radius 90 is one and one half the diameter of the pipe. Example: 6 inch 90 has a take- off of 9 inches. The take-off for short radius 90 would be the dia. of the pipe. Long radius 90 is 2 times the pipe diameter.

The take off for 90 degree pipe fittings is size of 90 plus half example 8" 90 8+4= is 12" take off 10" 90 10+5= 15" take off

Take cold inlet water pipe off tank. The dip tube sits below the fitting joining to the tank on the cold inlet side. You can pull it out and replace it.

It is located inside the smaller pipe or tube that is coming off the bottom of the evaporator. The pipe (tube) is under the bottom of the dryer. Disconnect the fitting and look inside the tube and you will see it. Take a pair of needle nose plairs and pull it right out.

An inside pipe wrench also called a pipe extractor. It drives into the broken off pipe and is then turned with a crescent wrench.Normally a extractor or inside pipe wrench does not work removing a pipe . What works best is the use of a hack saw blade and a chisel to cave in the threads after the threads are cut.. BECAREFUL not to cut into the fitting threads

The same as a short radius 90 of that same pipe size. I Rule of thumb, for example: 1/2 inch copper tubing you would take off 1/2 inch, likewise 3/4 tubing take 3/4 inch. Your question is 'pipe' are you actually using pipe, cutting and threading pipe? I am often asked questions and find that people are not using 'pipe'. Copper tubing, pvc, cpvc, dwv are quite forgiving when it comes to a slight miscut. Iron and galvanized piping is a different story, get it right the first time!

There is actually no question here

ok what is the inside diameter of a schedule 40 ,8" inch piece of pipe.? explain why pipe is pipe measured o.d and i.d.? how do you figure the travel for a 45 degree offset.10 inch pipe? what is the take out on a 6" inch short radius 90 ? 6"pipe flange 150 lb flange how many bolts ? what is the take off of a 6" 45 degree fitting. 1.those are some of the very simple questions you will find on a pipe fitters test am also nccer certified and that takes a company endorsement to get.and i think 68 or 70 is lowest you may score.that test has a sorted question's. **ANSWER KEY** **DISCLAIMER - I did not write the questions above and I seriously doubt that the "pipefitter" who did has ever seen an NCCER pipe test. However the questions which he asks are good, basic, pipe fitting knowledge questions. 1. 8" Nominal pipe size refers to i.d. on pipe up to 12" at which point the nominal pipe size refers to o.d. 2. Since pipe walls have a given thickness (schedule), it is necessary to consider both inside and outside diameter. 3. A 45 degree offset necessarily forms a 45-45-90 triangle with legs A and B being the same length and leg C (the hypotenuse) being the travel of the offset. There are a couple of ways to calculate the travel. The Pythagorean Theorem is easiest to remember...A2 + B2 = C2 Since A and B will always be the same measure in a 45o offset, it is only necessary to be able to measure one of the legs. Of course, remember to always measure from center line to center line of the pipes. Then plug into the formula and you get the travel from the center of 1 45o degree fitting to the other. Remember to subtract the take out for each fitting and you have the cut length for the pipe. Alternatively, you could also multiply the measure of the offset (A or B) by the number 1.414 and you would get the same result as C in the formula above. *Note: The pipe size is not really a relevant factor when calculating an offset, except when considering take out and center line measurement. 4. The take out for a 6" short radius 90o fitting is 6" In fact, the take out for all short radius elbows is equal to the pipe size. The take out for long-radius elbows is 1 1/2 x pipe size. So for a six inch long radius 90, the take out would be 9" 5. 8 bolts. The only time this information seems relevant is when you are making your own flanges. But it does seem to be a popular test question. Just remember that the answer to this question (class 150 flanges) is always 4 bolts up to 3" pipe, 8 bolts up to 8" pipe, 12 bolts up to 14" pipe, 16 bolts for 16" and 18" pipe, and 20 bolts for 20" and 24" pipe. Of course if its class 300 or above, just look it up. But honestly, you aren't gonna make many flanges. 6. 3 3/4" The take out for a 45o fitting is 5/8 times the pipe size. Some old pipe fitter will show you a trick of halving the pipe size, then halving that, then halving that and using the first and last number added together, but that's really stupid. Just remember that take out for 90's is 1 1/2 times the pipe size and take out for 45's is 5/8 times the pipe size.

It is the measurement of fittings for piping. It is the measurement of fittings for piping.

If it is 3 in. Then take off 3 in. and so on for what ever size you are use if it is 2 in. then 2 in.

It's your pipe size multiplied by 1.5

What it's the take out off 12 inch 90
