The ASTM A182 F316/L Stub End is a type of pipe fitting used to connect a pipe to a flange. It features a short length of pipe with a flared end that fits into a flange, providing a strong and secure connection. Made from F316/L stainless steel, it offers excellent resistance to corrosion and high temperatures. The “L” designation indicates a lower carbon content, which enhances weldability and reduces the risk of carbide precipitation during welding. Stub ends are commonly used in applications where frequent disassembly and maintenance are required, such as in chemical processing, petrochemical industries, and marine environments. They are available in various sizes and pressure ratings to accommodate different pipe sizes and system requirements.
