Stainless Steel 316 Weld Neck Flanges

A Weld Neck Flange is a critical forging component that is butt-welded to a pipe, providing a highly reliable connection point for assembling piping systems using bolts. The long tapered hub allows for stress to be transmitted smoothly from the flange to the pipe, making it ideal for high-pressure, high-temperature applications and severe services where integrity is paramount. While ASTM A193 B8M is the standard for the mating bolts, these flanges are manufactured under ASTM A182 Grade F316, which specifies the chemically equivalent Type 316 Stainless Steel. The forging process ensures optimal grain flow and strength. The Molybdenum content in this alloy provides exceptional corrosion resistance against chlorides, ensuring that the entire bolted joint, including the B8M stud bolts, maintains maximum durability in chemical, offshore, and power industries. Zeron Fasteners offers these flanges in various pressure classes (e.g., 150# to 2500#) and standards (ASME B16.5).
