Product Details of the Shipment
The supplied products included:
| Product | Size | Type | Material | Standard |
| 90° Long Radius Elbow | 2″ SCH40 (60.3 × 3.91 mm) | LR (R=1.5D) | ASTM A234 WPB | ASME B16.9 |
| 90° Short Radius Elbow | 2″ SCH40 (60.3 × 3.91 mm) | SR (R=1D) | ASTM A234 WPB | ASME B16.9 |
All elbows were manufactured with butt weld ends and carefully inspected before shipment.
ASME B16.9 A234 WPB 90 Degree Elbows
The main products supplied in this project were ASME B16.9 A234 WPB 90 degree elbows for industrial pipeline systems, which are widely used to change pipeline flow direction efficiently and safely.
What Is a 90 Degree Elbow?
A 90° elbow is a butt weld pipe fitting used to redirect pipeline flow by 90 degrees. Depending on the radius design, elbows are divided into:
- Long Radius (LR) elbows
- Short Radius (SR) elbows
Both types are widely used in industrial piping systems according to different installation requirements.
Long Radius vs Short Radius Elbows
Long Radius (LR) Elbow – R = 1.5D
The supplied ASME B16.9 A234 WPB 90 degree long radius elbow features a centerline radius equal to 1.5 times the pipe diameter.
Advantages of LR Elbows
- Lower pressure drop
- Reduced flow turbulence
- Better wear resistance
- Improved fluid flow efficiency
LR elbows are commonly used in:
- Oil & gas pipelines
- Water transportation systems
- Chemical processing pipelines
Short Radius (SR) Elbow – R = 1D
The supplied ASME B16.9 A234 WPB 90 degree short radius elbow features a centerline radius equal to the pipe diameter.
Advantages of SR Elbows
- Compact installation design
- Space-saving solution
- Suitable for limited installation areas
SR elbows are often used in:
- Compact piping systems
- Mechanical rooms
- Industrial equipment connections
