Description
Product Description
Stainless steel long radius elbow means the bending radius is 1.5 times of outside diameter, whatever it is 90 or 45 degree elbow. Long elbow radius offers a better corrosion resistance and strength. It is long service life makes it cos-effective. It suits in many industries applications.

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.
* 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
* 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.
* 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.

Packing & Delivery
Elbows need to be packed in wooden cases when they are shipped.The total amount of small elbows does not exceed 1 ton,Large size elbows need to be packed separately.
In addition, the wooden box packing clearly indicates the elbow size, steel number, batch number, manufacturer's trademark, etc.
