What do the elbow R=1.5D and R=1D codes mean?

Many customers receive pipe fitting drawings from the design institute and do not understand R=1.5D and R=1D on the elbow data of the pipe fittings. What do the codes of elbow R=1.5D and R=1D mean? Let’s learn together with you what the codes of elbow R=1.5D and R=1D mean.

The bending radius of the elbow is R=1.5D/R=1D, which is 1.5 times/1 times the diameter of the required bent object. D is the diameter of the object to be bent. R=1.5D is a long radius elbow, and the long radius elbow code is E (L). R=1D is a short radius elbow, and the short radius elbow code is E (S). In actual fluid pipeline construction, if we only talk about elbows without mentioning the long and short radii, we should use elbows with R=1.5D. The difference between these two types of elbows is that R=1.5D is relatively slow, while R=1D is relatively sharp. R=1D short radius elbows are mostly used in places where installation space is restricted, such as being too close to the wall or installation is restricted. This is the difference between R=1.5D long radius elbow and R=1D short radius elbow. I hope it will be helpful to you.
