What is the degree of a long radius elbow used in pipe fitting?

The degree of a long radius elbow commonly used in pipe fitting is 90 degrees. A long radius elbow is designed to provide a gradual change in direction when connecting pipes, which helps to reduce turbulence and pressure loss in the system. This type of elbow typically has a centerline radius that is one and a half times the diameter of the pipe, which is longer than that of a standard elbow.

A 90-degree elbow is particularly useful in applications where pipes need to be redirected sharply, such as when navigating around obstacles or changing the direction of flow efficiently. The design of a 90-degree long radius elbow allows for smoother flow than sharper angles, thus it is frequently the preferred choice in various piping systems.
