The ASTM F310 Concentric Reducer is a pipe fitting designed to connect two pipes of different diameters, with the smaller diameter pipe being aligned concentrically within the larger diameter pipe. This fitting is made from F310 stainless steel, which is known for its high resistance to oxidation and high-temperature corrosion. The F310 alloy, comprising a high percentage of chromium and nickel, provides enhanced durability and performance in extreme environments. The concentric reducer ensures a smooth transition between pipe sizes, minimizing turbulence and pressure loss while maintaining structural integrity in high-temperature applications such as those found in petrochemical plants, power generation, and aerospace industries.
