What is a 90 Degree Long Radius Elbow?
Pipe fittings that change direction in a piping system are called as elbows. The directional change is given in degree such as
45 or 90. 90 degree long radius elbow has the center line of elbow at 1.5 x NPS from eblow end. 3R elbow has center line at
3 x NPS from elbow end. A 90° elbow long tangent is a long radius (LR) with the centerline curvature equal to 1-1/2 times
the nominal pipe size (NPS) and a straight extension at both ends (long tangent) for 2 inch and larger sizes. Tangent elbows
provide a straight length at the end to accept a Slip-on Flange. The tangent end for the flange is not beveled.
