If your elbow is a short radius it is 1 times your nominal pipe diameter. If it is a long radius it is 1 1/2 times your nominal pipe diameter.show me the exact pattern of long radius
Rotate the pipe 180 degrees along a horizontal axis. Or look at the pipe from the other side. An angle that was not reflex will become reflex and conversely.
Elbow
The joint or bend of the arm; the outer curve in the middle of the arm when bent., Any turn or bend like that of the elbow, in a wall, building, and the like; a sudden turn in a line of coast or course of a river; also, an angular or jointed part of any structure, as the raised arm of a chair or sofa, or a short pipe fitting, turning at an angle or bent., A sharp angle in any surface of wainscoting or other woodwork; the upright sides which flank any paneled work, as the sides of windows, where the jamb makes an elbow with the window back., To push or hit with the elbow, as when one pushes by another., To jut into an angle; to project or to bend after the manner of an elbow., To push rudely along; to elbow one's way.
" 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.
Yes, the noun 'elbow' is a commonnoun, a general word for a joint of the arm, or something resembling a bent arm such as a piece of pipe or a bend in a river.
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.
When bending a pipe there are many different ways to do it. If you bend the pipe too much it can break and leak. So you need to make sure when bending pipe that you have the correct angle you want and don't over bend it.
Calculate as you would the surface of a cylinder who's height is the length of the central line of the pipe bend.(2*π*r*h)where:r is the (external) radius of the pipeπ is the constant 3.14159... andh is the length of the cylinder or the center-line of the pipe bend

wrought pipe bends means straight pipe bend using rotary draw pipe bender. or pipe bend by any method
You need to take what degreee turn you want divide that by how many welds you want that will give you the angle of miter cuts to find your starting piece a take the radius of bend muliply by tangent of miter cut
