The function of a elbow is to change direction or flow in a piping system

　　The function of steel elbow is to change direction or flow in a piping system. By default, there are 5 opportunities, the 45°, 90° and pipe elbows, all three in the "long radius" version, and in addition the 90° and 180° elbows both in the "short radius" version.

　　Elbows are split into two groups which define the distance over which they change direction; the center line of one end to the opposite face. This is known as the "center to face" distance and is equivalent to the radius through which the elbow is bent.

　　The center to face distance for a "long" radius elbow, abbreviated LR always is "1.1/2 x Nominal Pipe Size (NPS) (1.1/2D)", while the center to face distance for a "short" radius elbow, abbreviated SR even is to nominal pipe size.
