Long Radius Elbow has a curvature radius R equal to 1.5 times the pipe outer diameter (R=1.5D). Taking a 90° elbow with nominal diameter DN200 as an example, the center height of a long radius elbow is approximately 305mm, making it significantly longer. This dimensional difference gives the long radius elbow a slender overall shape, with a smooth and fluid arc in the curved section.
Due to its larger bending radius, the fluid flow path in a long radius elbow is gentler, resulting in smaller velocity changes and reduced impact force and friction on the inner wall, thus minimizing wear. The stable internal flow decreases turbulence-induced corrosion acceleration, enhancing corrosion resistance. Additionally, the near-straight flow state of the long radius elbow offers less flow obstruction, providing significantly lower fluid resistance compared to short radius elbows.
