ASTM A182/A240 ASME B16.47 Large Diameter Steel Flanges

ASTM A182/A240 / ASME B16.47 large-diameter steel flanges are engineered for high-performance pipeline connections, with key specifications and details as follows: – Size Range : 26″ – 60″ NPS (Nominal Pipe Size), including ASME B16.47 Series A (formerly API 605) and Series B (formerly MSS-SP-44) – Pressure Class : 75LB – 900LB (compliant with ASME B16.47 pressure rating standards) – Material Basis : – ASTM A182: Forged stainless steel/alloy steel (ensures high mechanical strength and structural integrity) – ASTM A240: Stainless steel plate (for welded flange manufacturing, meets corrosion resistance requirements) – Core Advantages : Large-diameter design with excellent pressure-bearing capacity, reliable sealing performance, and corrosion resistance-adaptable to harsh environments such as offshore and high-pressure industrial systems. – Application Scope : Designed for pipelines transporting liquids, particulates, and gases. Widely used in chemical processing, oil refining, boiler systems, power generation, food processing, offshore platforms, and other industrial fields requiring large-flow, high-pressure pipeline connections.
