What is the center to end dimension of a standard long radius 10 weld 90 ell?

The center-to-end dimension of a standard long radius 90-degree elbow (often referred to as a "long radius weld 90") is typically 1.5 times the nominal pipe diameter. For example, if the nominal pipe diameter is 2 inches, the center-to-end dimension would be 3 inches. This measurement is critical for ensuring proper fit and alignment in piping systems.
