90° Elbow
90-degree elbow also called “90 bends or 90 elbows”, are
manufactured as SR (Short Radius) elbows and LR (Long Radius) elbows. SR (Short
Radius) elbows have a Center-to-Face dimension of 1.0 X diameter and are
typically utilized in tight areas where clearances are a problem. LR (Long
Radius) elbows have a Center-to-Face dimension of 1.5 X diameter and are the
more common type and used when space is out there and flow is more critical.
this is often a fitting device that is bent in such how to supply 90-degree
change within the direction of flow of the content within the pipe.
