Short-radius elbow problem
Thread Content
I saw on the forum that short-radius elbows (R=1.0DN) are commonly used in situations where space is limited. Its maximum operating pressure should not exceed 0.8 times that of a long-radius elbow of the same specification. I don’t understand what this means. For the same pipeline, my operating pressure is fixed; however, due to the large diameter and limited space, I am forced to use a short-radius elbow. So does this mean that, regardless of whether it is a long-radius or short-radius elbow, the operating pressure remains the same, but the maximum operating pressure (which is presumably the design pressure) is 0.8 times that of a long-radius elbow?
Mainly, the strength of short elbows is lower than that of regular elbows.
