This 90° weld elbow is available in 304 or 316L stainless steel. This precision crafted sanitary butt-weld 90° elbow features a standard machine unpolished finish. This unpolished elbow is used to change flow direction in many applications across many industries when a sanitary finish is not required.

* In a long radius (LR) elbow the radius of curvature is 1.5 times the nominal diameter. In a short radious (SR) elbow the radius of curvature is 1.0 times the nominal diameter of the pipe. LR elbows give less frictional resistance to the fluid compared to the SR
* The LR elbow creates less less pressure drop i.e less friction on the other hand The SR elbow creates more pressure drop i.e more friction.
* The cost of SR elbow is more than LR elbow.

Difference in Design:
* Short Radius Elbow (SR Elbow): Has a centerline bend radius equal to the nominal pipe diameter. Has a tighter bend.
* Long Radius Elbow (LR Elbow): Features a bend radius at least 1.5x the nominal pipe diameter. More gradual, longer bending arc


Key Contrasts:
* Pressure drop - Lower in long radius for a given flow rate. Less turbulent flow avoids excessive fluid momentum changes.
* Material stress - Higher in short radius fittings with tighter bending. Potential for cracking over time.
* Pipe alignment - Long radius makes alignment with adjoining straight pipe portions easier and minimizes system stress.


Typical Applications:
* Long radius elbows commonly preferred for critical gas/steam/water flow for power plants, chemical/oil lines
* Short radius often used for non-binding, lower temperature/pressure lines where space is limited.
