The Welding Neck Flange is an essential component in piping systems, ensuring secure and leak-proof connections between pipes, valves, and equipment. Manufactured from high-quality forged material F51, this flange offers excellent mechanical properties, superior strength, and outstanding corrosion resistance for demanding industrial applications.
Available in Raised Face (RF) and Flat Face (FF) options, the flange provides versatile sealing solutions. The Raised Face design enhances sealing capabilities for high-pressure applications, while the Flat Face option is suitable for use with brittle materials like cast iron.
Compliant with EN 1092-1 Type 11 specifications, these flanges ensure compatibility and interchangeability in various piping systems. The product is also available in stainless steel variants including 1.4404, 1.4541, and 1.4571 for aggressive environments.
