The Welding Neck Flange is a critical component designed for high-pressure and high-temperature piping systems, providing reliable leak-proof connections between pipes, valves, and equipment. Manufactured using advanced forging techniques, this flange ensures superior strength, durability, and performance under demanding industrial conditions.
This particular Welding Neck Flange is constructed from high-quality Carbon Steel (steel number 1.8845), corresponding to X10CrMoVNb9-1 (F91) alloy. This material offers excellent mechanical properties with exceptional resistance to creep and oxidation at elevated temperatures, making it ideal for power generation, petrochemical, and heavy industrial applications.
The flange complies with EN 1092-1 standards, ensuring precise dimensions, tolerances, and performance criteria that meet international requirements. It features WELD-END PREPARATION FOR FLANGES TYPE 35, which optimizes the welding process by providing an engineered bevel for strong, consistent weld joints.
