The ASTM A182 F316/L 90° Elbow is a crucial pipe fitting used to change the direction of flow in a piping system by 90 degrees. This elbow is made from F316/L stainless steel, a material known for its superior resistance to corrosion and high temperatures. The “L” in F316/L signifies a lower carbon content compared to standard F316, enhancing its weldability and resistance to sensitization. This makes it particularly suitable for high-temperature and corrosive environments, such as chemical processing, marine applications, and petrochemical industries. The 90° Elbow is designed to facilitate smooth transitions in pipelines, helping to minimize pressure loss and turbulence.
