The ASTM A694 F65 WN RF NACE MR0175, ASME B16.5 flange is engineered for high-temperature, high-pressure, and severe service conditions. This product utilizes high-strength ASTM A694 F65 forged steel with a pressure rating up to Class 2500. Its unique Welding Neck design optimizes stress distribution and enhances pipeline structural stability. The Raised Face sealing design provides powerful gasket compression force, effectively preventing media leakage and ensuring project safety.
Due to its high-strength mechanical properties and silicon content, the ASTM A694 F65 WN RF NACE MR0175, ASME B16.5 flange offers superior high-temperature stability (-40°C to 200°C) and cryogenic toughness (down to -162°C) compared to standard stainless steel flanges. It maintains material integrity and performance under extreme temperatures, making it an ideal choice for demanding applications in the chemical and energy industries.
Manufactured using vacuum degassing and normalizing + tempering heat treatment processes, the flange exhibits exceptional resistance to Sulfide Stress Corrosion Cracking and Hydrogen Induced Cracking. Its outstanding corrosion resistance, particularly in environments containing H₂S and other corrosive media, significantly extends equipment service life and reduces maintenance costs.
