The ASME B16.5 Class 600 Socket Weld Flange refers to a flange type where the pipe end is inserted into the flange's socket hole, and the connection is achieved through an outer fillet weld. Its structure is similar to a slip-on flange with a neck, but it features a small step on the inner diameter to position the pipe insertion depth and ensure welding accuracy. HT PIPE supply all different types and scales of flanges. Please feel free to contact us for further product information and pricing.
ASME B16.5 Class 600 Socket Weld Flange Key Advantages
Easy Installation: The pipe only needs to be inserted into the flange's socket hole, aligned, and then welded with a single-sided fillet weld to complete the connection. Compared to weld neck flanges, the installation process is simpler, requiring no complex beveling, significantly improving construction efficiency and offering a cost advantage.
Pressure Resistance: Designed with a Class 600 pressure rating, it is suitable for medium and high-pressure pipeline systems. Combined with the socket weld sealing structure, it can effectively withstand system pressure fluctuations, reducing the risk of leakage and making it suitable for high-pressure operating conditions.
High Adaptability: The size range covers NPS 1/2 to NPS 24, allowing for flexible selection based on pipeline requirements. It is also compatible with various sealing surface types, adapting to the sealing requirements of different media and operating conditions.
Economic Efficiency: Compared to welding flanges and loose flanges, SW flanges have lower manufacturing costs and shorter installation time, effectively reducing the overall construction cost of piping systems. They also offer good versatility, facilitating later maintenance and replacement.
ASME B16.5 Class 600 Socket Weld Flange Sealing Surface Types
Raised Face (RF): The most widely used type, featuring a raised sealing surface. It is used with spiral wound gaskets, asbestos rubber gaskets, etc., and is suitable for most medium- and high-pressure, non-corrosive, or weakly corrosive media applications.
Flat Face (FF): The sealing surface is flat. Primarily used for low-pressure, corrosive media, or applications requiring connection to flat valves or equipment. Sealing reliability is relatively weaker, requiring the use of suitable soft gaskets.
Raised Face (MFM): The sealing surface is divided into a raised surface and a concave surface. The gasket is embedded in the concave surface, which can effectively prevent the gasket from shifting and provide better sealing performance. It is suitable for working conditions with large pressure fluctuations and high sealing requirements.
