The ASTM A182 F316/L Short Radius (SR) Elbow is a pipe fitting designed to change the direction of the piping system with a shorter bend radius compared to long radius elbows. Made from F316/L stainless steel, this elbow offers excellent corrosion resistance and high-temperature performance. The “L” signifies a lower carbon content, which improves weldability and reduces the risk of carbide precipitation during welding. The short radius design allows for a more compact installation where space is limited, though it may induce higher pressure drops and turbulence compared to long radius elbows. It is commonly used in various industries such as chemical processing, petrochemical, and marine applications where space constraints are a factor.
