Stainless steel/Duplex steel forged flanges/ ANSI B16.5/EN1092-1/SABS-1123

Applications:

Oil and Gas Industry: Used in pipelines, refineries, and offshore platforms for connecting pipes, valves, pumps, and other equipment. Duplex flanges are especially suitable in environments where corrosion resistance is critical, such as subsea and sour gas applications.
Chemical Processing: Ideal for connecting pipes in chemical plants where highly corrosive fluids and gases are processed, with stainless steel providing excellent resistance to acids, caustics, and harsh chemicals.
Power Generation: Deployed in high-pressure steam lines, heat exchangers, and cooling systems where strength, resistance to thermal expansion, and durability under high temperatures are essential.
