The ASTM A182 F304 Socket Weld Flange is a high-pressure stainless steel fitting engineered for critical piping systems requiring secure, leak-tight connections. Manufactured from corrosion-resistant 304 stainless steel to ASME B16.5 standards, this 3-inch (DN80) flange is rated for Class 1500 LB (PN250) service, making it suitable for extreme pressure applications in oil and gas, chemical processing, and power generation. The socket weld design provides enhanced structural integrity and flow characteristics compared to threaded alternatives.
