Carbon Steel Butt Weld Long Radius 45° Elbow ASTM A234

We offer Carbon Steel Butt Weld Long Radius 45° Elbows, manufactured to the stringent ASTM A234 Grade WPB standard, and are engineered for precise directional changes in critical piping systems. These elbow fittings facilitate a smooth, gradual 45-degree alteration in flow, minimizing turbulence and pressure drop while ensuring exceptional structural integrity and leak-proof performance across a multitude of industrial applications.

Key Features:

High-Grade Material: Produced from premium carbon steel (ASTM A234 Grade WPB), guaranteeing outstanding mechanical properties, excellent weldability, and resilience against operational stresses and pressures.
Long Radius Design: The "Long Radius" configuration ensures a gentler change in flow direction compared to short radius elbows, significantly reducing friction, erosion, and pressure loss within the pipeline.
Butt Weld Connection: Designed for robust butt welding, which creates a permanent, high-strength, and completely leak-proof joint, indispensable for systems operating under high pressure or elevated temperatures.
Seamless Flow Optimization: The smooth internal bore and long radius bend are specifically designed to optimize fluid dynamics, promoting efficient flow and reducing wear on the fitting itself.
Precision Manufacturing: Produced with meticulous attention to dimensional accuracy and tight tolerances, ensuring seamless fit-up and straightforward installation with existing pipework.
Versatile Wall Thicknesses: Available in a comprehensive range of schedules (e.g., Sch 40, Sch 80, Sch 160, XS, XXS) to perfectly match varying pipeline pressure ratings and wall thickness requirements.

Advantages:

 

• Enhanced Flow Efficiency:  The long radius and 45-degree angle significantly reduce hydraulic losses and turbulence, leading to more efficient system operation and lower energy consumption for pumping.
• Reduced Erosion & Wear:  The gradual bend minimizes localized velocity increases and impingement, prolonging the lifespan of the elbow, especially in abrasive or high-velocity fluid applications.
• Superior Durability:  Constructed from robust carbon steel, these elbows are built to last, offering excellent resistance to fatigue and stress, thereby reducing maintenance needs and replacement costs.
• High Integrity & Safety:  Butt weld connections provide the most reliable and secure joint possible, critical for maintaining system integrity and operational safety in demanding environments.
• Cost-Effective Performance:  Carbon steel offers an optimal balance of high performance, durability, and cost-effectiveness, providing a reliable and economical solution for most industrial piping needs.
• Full Compliance:  Manufactured in strict adherence to ASTM A234 and ASME B16.9 standards, ensuring global acceptance, interchangeability, and consistent quality.

Applications:

 

Our Carbon Steel Butt Weld Long Radius 45° Elbows are indispensable across a wide spectrum of industrial sectors, where a controlled, gradual change in pipeline direction is crucial:
