for example : if we take a size of diameter 480mm fabricated pipe of wall thickness 3mm from this we going make a elbow by formula
CMof Circle X required degree by 360 X 2 X no .of cut needed
= 1520 X 90 / 360 X 2 X 3
= 64mm
make a divde four lines on pipe
mark of line of half of diameter = 220mm in two lines next to next parallel
mark 6.4 cm by one half to another half
on both lines
then u make cut it
u will get elbow
cut a 22 1/2 out of it
There are far too many variables to provide an answer to this question. But we do know that for linear welds, like the joining of steel plates in something like, say, shipbuilding, a robotic welder can outweld any human welder. And the longer the time a study is conducted the farther the machine outpaces the man. But in welding, say, small piping with many elbows and tees, the human can outpace any robot. Welding rates vary with the geometry of the material being welded, and according to who or what is doing the welding, and under what conditions.
" All bends are elbows but all elbows are not bends." Infact, the pipe is bent to form an elbow. Elbows are pre-fabricated and are firm in design. There are issues with bends since the tickness at the bend radius reduces as we bend the pipe. Sharp bends are normally called Elbows. Bends typically have a minimum bending radius of 1.5 times pipe radius (R). If this bending radius is less than 1.5R, it is called Elbow. Reference to any international / industry standard need to be traced. 1.5, 3 & 4.5 R are the most common bending radii in industry.
A pipe flange is used in the assembly of pipe to pipe or other things like valves, elbows etc. The flanges are bolted together, creating several lengths of pipe or other assemblies.
Yes... typically killed carbon steel is used. However, you will need to watch out that your lean amine system is not too lean. You want a level of H2S in there that will allow a protective layer of iron sulfide to lay out in the piping and not be removed. If the lean amine loadings are too low in H2S content, that layer can be removed and it will no longer be protected. In this case be watchful of higher velocity areas. Example: small bore piping, reducers, tees, elbows... pay attention to the flow directions and check your areas of "impingement" with Ultrasonic thickness measurements or profile radiography.
Put your hands in front of you with your elbows straight out to your sides and press your palms of your hands together. It works i promise!!!
Its really basic, you grab the bar while its on the rack and and shoot your elbows(by that i mean to not have your elbows facing down but instead straight) while its resting on or a little below the collar bone. Then squat down below parallel and then back up.

Giraffes don't have elbows.

anne murray gets cold elbows
Chafed Elbows was created in 1966.
elbows: codos (as in the elbow on an arm)
The plural form of elbow is elbows.
the Military press is an exercise that consists of standing straigh up, arms stretched straight out, then bend at the elbows so your hands point towards the sky, and there is a 90 degree angle at your elbows, then raise your arms until they are completely vertical, and repeat. many times.
This is one exercise that can help to enhance one's breasts: Stand straight; bend your elbows slightly, keeping your hands on your hips; try to make your elbows touch each other behind your back; stretch for 10-15 seconds. Repeat 8 times.
You keep your arms straight without bending any elbows and swing them, pushing yourself along with the poles. Almost like skiing on land.
