The ASTM F304L Reducing Tee is a pipe fitting used to connect three sections of pipe, where two of the pipes are of different diameters. This fitting allows for the reduction of pipe size at the junction point, facilitating the transition from a larger to a smaller pipe. Made from F304L stainless steel, it offers excellent resistance to corrosion and high temperatures, making it ideal for use in chemical processing, oil and gas, and power generation industries. The low carbon content of F304L minimizes the risk of carbide precipitation during welding, ensuring robust performance and longevity in welded systems. The reducing tee is designed to maintain efficient flow while accommodating different pipe sizes.
