Quantity
The ASTM A182 F316 Flange is a premium-grade forged flange engineered for demanding industrial applications requiring exceptional corrosion resistance and reliable sealing performance. Manufactured from F316 stainless steel—a molybdenum-bearing austenitic grade—this flange offers superior resistance to pitting and crevice corrosion in chloride environments, outperforming standard 304 stainless steel . The 2-inch size with 150LB pressure rating conforms to ASME B16.5 dimensional standards, ensuring compatibility with industry-standard piping systems .
Design & Construction
This Weld Neck (WN) flange features a tapered hub that provides reinforcement at the flange-pipe junction, reducing stress concentration and enhancing structural integrity . The Raised Face (RF) sealing surface, combined with the flange's inherent stiffness, ensures a leak-tight connection when paired with appropriate gaskets. The forged construction process refines the grain structure, delivering superior mechanical properties including high tensile strength, excellent toughness, and resistance to thermal fatigue .
