ASME B16.9 A234 WPB 180 Degree Long Radius Elbows
The main product in this order was the ASME B16.9 A234 WPB 180 degree long radius elbow for industrial pipeline systems, a commonly used butt weld fitting in high-performance piping applications.
What Is a 180 Degree Long Radius Elbow?
A 180° long radius elbow, also called a return bend, is used to reverse the direction of fluid flow in a pipeline system. Compared with short radius elbows, long radius elbows provide smoother flow transition and lower pressure loss.
The centerline radius of a long radius elbow is typically 1.5 times the nominal pipe size.
Advantages of A234 WPB 180 Degree Long Radius Elbows
Improved Flow Efficiency
The long radius design minimizes turbulence and pressure drop during fluid transportation.
Better Wear Resistance
Smoother flow characteristics help reduce internal erosion caused by high-speed media.
Suitable for High-Pressure Systems
The SCH80 wall thickness provides enhanced strength for demanding industrial applications.
Excellent Weldability
ASTM A234 WPB carbon steel offers reliable welding performance for field installation and fabrication.
Haihao Group manufactures ASME B16.9 A234 WPB 180 degree long radius elbows for industrial pipeline systems according to strict international quality standards.
