Seamless And Welded Carbon Steel Elbows For Cost-effective Piping Applications
Carbon steel elbows are robust pipe fittings designed for industrial piping systems, compliant with astm a234 and asme b16.9 standards. these seamless or welded elbows, such as astm a234 wpb, offer excellent strength and erosion resistance, making them ideal for boiler pipeline protection in industries like oil and gas, power generation, and general industrial piping.
Carbon Steel Elbows are robust pipe fittings designed for industrial piping systems, compliant with ASTM A234 and ASME B16.9 standards. These seamless or welded elbows, such as ASTM A234 WPB, offer excellent strength and erosion resistance, making them ideal for boiler pipeline protection in industries like oil and gas, power generation, and general industrial piping.
Carbon steel elbows are manufactured through hot-forming or cold-forming processes, ensuring durability in moderate temperature ranges (-29°C to 425°C). With a composition including carbon (≤0.30%) and manganese (0.29-1.06%), they provide good mechanical strength and moderate corrosion resistance. Available in long-radius (LR, R=1.5D), short-radius (SR, R=1D), and reducing configurations, these elbows support angles of 90°, 45°, and 22.5° for versatile industrial piping designs.
These elbows support welding, bending, and flanging, with good weldability. Available in sizes from 1/2” to 24” (DN15 to DN600) and wall thicknesses from SCH 10 to SCH 160, they meet diverse pipeline requirements. Rigorous testing, including tensile, impact, and hydrostatic tests, ensures compliance with ASTM A234 standards for reliable performance.
Carbon steel elbows can be coated (e.g., FBE, 3LPE, galvanizing) to enhance corrosion resistance, protecting against rust in moderately corrosive environments. Their cost-effectiveness and strength make them ideal for boiler pipeline protection in oil and gas pipelines, power plants, and industrial systems where high corrosion resistance is not critical.
For engineers seeking cost-effective and durable industrial piping solutions, carbon steel elbows deliver reliable performance, addressing challenges like mechanical stress and moderate corrosion in demanding applications.

Carbon steel elbows are first classified by their radius of curvature, which can be divided into long radius elbows and short radius elbows.
Depending on pressure rating, 17 schedule levels are available: Sch5s, Sch10s, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS, Sch80, Sch100, Sch120, Sch140, Sch160, XXS. Most commonly used schedules are STD and XS.
Based on the angle, common elbows include: 45°, 90°, and 180°.
Radius of curvature is a measure of how sharply a curve bends. It is defined as the reciprocal of curvature, which itself is the rate of change of the tangent angle with respect to arc length. A smaller radius means a sharper bend, while a larger radius indicates a gentler curve.
For long radius elbows, the radius of curvature must be controlled within tolerance. For instance, if R = 1.5D, the actual curvature should not deviate beyond the specified range.

Note: Carbon steel elbows, including ASTM A234 WPB, are designed for cost-effective and durable industrial piping. Contact a certified supplier for detailed specifications.
Formed by hot pressing or forging, directly welded to pipe with beveled ends for full penetration weld. Suitable for high pressure & high temperature pipelines.
Features a socket at the end where the pipe is inserted before welding. The actual end diameter is slightly larger than pipe OD for proper fit.
Similar to socket weld elbows but with threads inside for easy installation & removal. Ideal for repair and maintenance work in low/medium pressure pipelines.
