Information

Socket Weld Flange 3/4'' 316L 600LB RF SCH80S is a Socket Weld (SW) flange in 3/4'' size, manufactured from 316L stainless steel, with a 600 LB pressure class, RF (Raised Face) facing, and SCH80S wall thickness, in accordance with ANSI/ASME B16.5. It is intended for installations requiring high mechanical strength, excellent corrosion resistance, and reliable operation in demanding industrial conditions.

Where should this flange be used?

Socket Weld Flange 3/4'' 316L 600LB RF SCH80S is an optimal choice wherever small-diameter piping systems operate under high pressure and with aggressive media.

Typical applications:

• Steam and steam-gas installations in industrial boiler rooms (connections to valves, safety valves, and steam pipelines)
• Pipelines transporting chemically aggressive media (acids, alkalis, saline solutions) in chemical and petrochemical plants
• Marine and offshore installations (pipeline systems on platforms and marine equipment) – corrosion resistance in marine environments
• Heat exchange systems and heat exchangers using aggressive coolants and higher pressures

Key Features and Benefits

• Corrosion resistance: 316L stainless steel provides excellent resistance to intergranular corrosion and chlorides, making it suitable for marine environments and aggressive chemical media. The low carbon content (L) minimizes the risk of sensitization during welding.
• High-pressure performance: the 600 LB pressure class combined with the SCH80S wall thickness provides reliable operation in high-pressure systems.
• Leak-tight and durable connection: the Socket Weld system eliminates the need for pipe beveling and creates a durable, mechanically stable connection. The RF facing simplifies the selection and installation of gaskets (e.g. graphite or PTFE), providing reliable sealing.
