Flat Face Welding Neck Flange ASME B16.5 Standard
Product Description
The Welding Neck Flange is a critical component designed for industrial piping systems requiring robust performance under high pressure and temperature conditions. Manufactured in compliance with EN 1092-1 standards, this flange ensures reliable and safe operation in demanding environments by providing secure, leak-proof connections between pipes, valves, and equipment.
Constructed from high-quality chromium molybdenum steel (11CrMo9-10 grade), this flange offers superior strength, excellent corrosion resistance, and outstanding mechanical properties at elevated temperatures. It is particularly suitable for power plants, petrochemical industries, and oil and gas applications where durability and long service life are essential.
Available in both Flat Face (FF) and Raised Face (RF) configurations, the flange provides installation flexibility. The Flat Face design prevents damage to equipment faces, while the Raised Face concentrates pressure on the gasket area for improved sealing in higher-pressure applications.
Rated at 600 pressure class with a long weld neck measuring L=697MM, this A182 F11 class 2 welding neck flange reduces stress concentration, improves flow characteristics, and prevents turbulence and erosion, ensuring extended service life for critical piping infrastructure.
