A 20# Steel 45 Degree Elbow refers to a pipe fitting made from 20# carbon steel that changes the direction of the piping system by 45 degrees.
45 Degree Elbow: This indicates the fitting is bent at a 45-degree angle, used to change the direction of a pipeline.
Steel: The material of the fitting is steel. The specific type of steel isn't fully defined by "20#".
20#: This likely refers to the nominal pipe size (NPS) of 20 inches. The "#" symbol is often used to denote NPS.
Long Radius (LR): The centerline radius of the bend is 1.5 times the nominal pipe size (1.5D). Long radius elbows offer less friction loss.
Short Radius (SR): The centerline radius of the bend is equal to the nominal pipe size (1D). Short radius elbows are more compact.
