The ASTM F310 Equal Cross is a pipe fitting that connects four pipes of the same diameter in a cross configuration. Made from F310 stainless steel, this fitting is designed to withstand extreme temperatures and corrosive environments. The F310 material offers high resistance to oxidation and high-temperature creep, making it suitable for demanding industrial applications. Equal crosses are commonly used in piping systems to facilitate changes in direction and flow, or to connect multiple pipes in a central hub. They are typically employed in sectors such as petrochemical processing, power generation, and aerospace, where reliability and performance under severe conditions are crucial.
