Elbow problem
Thread Content
Is the 1.5 times elbow we usually call a 90-degree elbow? 1.5 times refers to five times. In terms of elbow standards, why are the radius calculation results of the two different? Please share your opinions.
R=1.5DR elbow curvature
1.5D elbow is not necessarily 90°, but also 30°, 45°, 60°, etc. 1.5 means that the radius of curvature of the elbow (pipe center) is 1.5 times the nominal diameter of the pipe
Isn't it stated in the elbow standards? I've seen it in books before.
The radius of curvature is R=1.5D, but not all are applicable
Long radius elbow refers to its radius of curvature equal to 1.5 times the outer diameter of the pipe, that is, R=1.5D； A short radius elbow means that its radius of curvature is equal to the outer diameter of the pipe, that is, R=1.0D. (D is the elbow diameter, R is the radius of curvature)
