The ASTM A182 F316 threaded/screwed union is a fitting designed to join two pipes together with the ability to disassemble for maintenance or modification. Made from F316 stainless steel, this union offers excellent resistance to corrosion and high temperatures, making it suitable for harsh environments such as chemical processing, marine, and petrochemical industries. The F316 alloy, comprising 16-18% chromium, 10-14% nickel, and 2-3% molybdenum, provides enhanced protection against chloride-induced corrosion and oxidation. The union features male and female threads that allow it to be securely connected without the need for welding. It is designed for high-pressure applications, with mechanical properties including a minimum tensile strength of 515 MPa and yield strength of 205 MPa. The union provides a reliable, durable connection that can be easily assembled and disassembled as needed.
