ASME B16.5 Certified ASTM A182 F11 Flanges: Ideal for High-Pressure High-Temperature Applications

Our ASME B16.5 certified ASTM A182 F11 flanges are engineered for extreme high-pressure and high-temperature (HPHT) industrial applications. Crafted from 1% Cr-0.5% Mo alloy steel, these flanges deliver exceptional creep resistance, thermal stability, and oxidation resistance at temperatures up to 593℃. Compliant with ASME B16.5 standards, they cover NPS 1/2–24 and pressure classes 150–2500, ensuring universal compatibility for global pipeline projects. Produced via precision forging by Dingxiang Jinyu, each unit undergoes rigorous non-destructive testing, guaranteeing structural integrity for power plant boilers, petrochemical reactors, and high-temperature steam pipelines. Trust our reliable flanges to optimize your HPHT system performance.
