The ASTM A182 Grade 347 stainless steel socket weld reducing tee is a fitting used to connect three sections of piping while allowing for a change in pipe size. Made from Grade 347 stainless steel, this tee provides excellent resistance to intergranular corrosion and high-temperature environments, thanks to the addition of columbium (niobium). The socket weld design ensures a strong, permanent connection, ideal for high-pressure and high-temperature applications. Its reducing feature allows for the connection of different pipe sizes, making it versatile for various piping configurations in industries such as petrochemical, chemical processing, and aerospace.
