Stainless Steel Forged Flanges
Product Overview
Stainless steel forged flanges are critical components for industrial and pipeline systems, providing high strength, corrosion resistance, and leak-proof performance. Manufactured from 304, 316, or 316L stainless steel, forged flanges are suitable for high-pressure, high-temperature, and corrosive environments.
Forged flanges offer superior mechanical properties, precise dimensions, and durability compared to cast flanges, making them ideal for oil & gas, petrochemical, water, and LNG pipelines, as well as industrial processing systems. They comply with ASME, ASTM, ISO, and API standards, ensuring global quality and reliability.
