Product Description: ASTM A105N Carbon Steel RF Weld Neck Flange (ANSI / EN1092-1 Dual Standard)
Product Overview: Globally Compatible, High-Strength A105N Weld Connection
Our Carbon Steel Weld Neck Flange is a high-strength component engineered for piping connections that demand international interoperability. Its unique advantage lies in its strict compliance with both ANSI (US Standard) and EN1092-1 (European Standard), ensuring versatility and seamless compatibility across major global projects.
The flange body is manufactured from high-quality ASTM A105N Forged Carbon Steel, where the 'N' denotes Normalized heat treatment. This process significantly enhances the material's mechanical toughness and impact resistance, allowing it to perform exceptionally well under high-pressure, high-stress conditions. The Weld Neck structure, combined with the Raised Face (RF) sealing design, offers the highest level of safety and leak prevention for critical services in oil & gas, petrochemical, and power generation sectors.
