45 Degree Elbow

An elbow is a pipe fitting used to create a change in direction between two lengths of pipe or tubing, typically at a 90- or 45-degree angle. They have threaded ends (usually female). The fitting is referred to as a reducing elbow or reducer elbow when the two ends are of different sizes.

Another name for a 45-degree elbow is a "45 bend." It is a fitting that has been bent to change the direction of flow in the pipe by 45 degrees. It is sometimes referred to as a "quarter bend" and is used to shift the direction of pipes.

the radius of curvature of a carbon steel elbow is separated into long radius elbows and short radius elbows. The term "long-radius elbow" describes an elbow with a radius of curvature that is 1.5 times the tube's outer diameter, or R= 1.5D. A short-radius elbow has a radius of curvature that is the same as the tube's outer diameter, or R=1.0D. (D represents the elbow's diameter, and R represents the radius of curvature. Folds are another way to express D.) The same standards as in the U.S. tube are: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160. If there are 17 levels dependent on the pressure rating.
