What dimensions do 1.5D or 1.0D refer to when talking about elbows?
The classification method for elbows is based on their radius of curvature; they can be divided into elbows with a large radius and those with a small radius. A long-radius elbow refers to one whose radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D. A short-radius elbow refers to one whose radius of curvature is equal to the outer diameter of the pipe, that is, R = D. In the formula, D is the diameter of the elbow, and R is the radius of curvature.
The dimension from the center of one side of the elbow to the other side.
As mentioned above, a long-radius elbow refers to one whose radius of curvature is equal to 1.5 times the outer diameter of the pipe, that is, R = 1.5D. ”Not entirely accurate. This is because a radius elbow has a curvature radius that is often more than 1.5 times the outer diameter of the pipe, and it is also classified as a long-radius elbow.
