The ASTM F310 LR (Long Radius) Elbow is a type of pipe fitting designed to change the direction of flow in piping systems. Made from F310 stainless steel, this elbow is ideal for high-temperature and corrosive environments due to its superior oxidation and corrosion resistance. The long radius design ensures a gradual change in direction, reducing turbulence and pressure loss compared to short radius elbows. This fitting is commonly used in industries such as petrochemical, aerospace, and power generation, where smooth transitions and durability are essential for maintaining system efficiency and extending the lifespan of the piping system.
