90 Degree Short Radius Elbow

90 degree elbows are manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows. 90 Degree Short Radius Elbow is generally used in tight areas. They are available only at 90 degrees but they can be cut to lesser degree if required as per piping layout. The centerline radius of short radius elbows is the same as its nominal pipe diameter.
