Our ANSI B16.5 carbon steel blind flange is engineered to meet strict international standards, ideal for high-pressure pipeline systems requiring reliable sealing. Crafted from premium carbon steel grades (A105, Q235B, 20#), it boasts exceptional strength, temperature resistance, and wear resistance, adapting to Class 150–2500 pressure ranges and diverse working conditions.
Precision-machined to ensure dimensional accuracy, its flange face (RF/FF/Raised Face) delivers tight sealing, effectively preventing media leakage in oil & gas, chemical, power generation, and petrochemical industries. Designed for pipeline shutdown, maintenance, or terminal sealing, it offers seamless compatibility with ANSI-standard pipes and fittings.
With rigorous quality control through non-destructive testing (NDT) and pressure inspections, our product guarantees long-term durability and operational safety. We provide flexible customization for size, thickness, and surface treatment, supported by ready stock and prompt delivery to meet global project timelines. A cost-effective and trustworthy solution for high-pressure industrial applications.
