Regarding the issue of the short and long radii of pipe elbows

Thread Content

I would like to ask everyone: the notation R=1.5D is used for long-radius elbows, while R=1.0D is used for short-radius elbows. Which standard specifies this notation? I couldn’t find it; it’s not listed in GB/T12459 either! Thank you!

It’s in GBT 12459-2017; check there again – there are also 3D elbows mentioned in it

Most of these are just conventional practices. .

It should be denoted as 90E(L) and 90E(S), right?

In GBT12459, there are 90E(L) and 90E(S); as can be seen from the table, the long-radius elbow has a radius of 1.5D, while the short-radius elbow has a radius of 1.0D
