The ASTM F304L Equal Cross is a pipe fitting used to connect three sections of pipe at a single point, forming a cross-shaped junction. Constructed from F304L stainless steel, this cross provides excellent resistance to corrosion and high-temperature environments, making it suitable for use in various industries, including chemical processing, oil and gas, and power generation. The F304L grade, with its low carbon content, reduces the risk of carbide precipitation during welding, ensuring durability and longevity in welded systems. The equal cross design allows for equal flow distribution through each of the three pipe sections, facilitating efficient and balanced fluid handling in the piping system.
