Butt Weld Elbow Pipe Instrumentation Fitting
Product Description
Butt weld long radius 90 degree elbow is used for 90 degree turn on piping in butt weld piping system. Long radius elbows are preferred due to their low pressure drop. They can also be cut at lesser degree if required in piping layout. Their centerline radius is 1.5 times the nominal pipe diameter. 90-Degree elbows with a straight extension at one end (long tangent) are still available in STD weight if required.
