This manufacturer produces ASTM A234 WPB 45-degree seamless elbows with long radius geometry per ASME B16.9 standards, enabling gradual directional changes that minimize flow resistance and pressure drop. The carbon steel construction offers excellent weldability and durability for standard industrial service. Sized at 22 inches (DN550) with SCH 10 wall thickness, these butt weld elbows suit medium-pressure piping systems.
