An SS (Stainless Steel) Flange is a mechanical ring or disc used to connect pipes, valves, pumps, and equipment in a piping system, creating a strong, leak-proof, and reusable joint, known for excellent corrosion resistance and strength, making it ideal for harsh environments in oil & gas, chemical, food processing, and water treatment industries. They come in various types (like Weld Neck, Blind, Slip-On, Lap Joint, Socket Weld) and materials (like SS 304, 316) to meet specific pressure, temperature, and corrosive application needs, conforming to standards like ANSI, ASME, and ASTM. Key Characteristics:

• Material: Primarily iron, chromium, and nickel, offering strength and rust resistance. Common grades include 304/304L (general purpose) and 316/316L (enhanced chloride/corrosion resistance).
• Function: Connects components, seals pipelines, and provides a strong connection point for bolting.
• Durability: Withstands high pressure, high temperatures, and corrosive substances, ensuring system integrity.
• Application: Used across diverse sectors, including petrochemicals, pharmaceuticals, water treatment, and power generation. 

Common Types:

• Weld Neck Flange (WNRF): Tapered hub for high-pressure, high-temperature service, reducing stress.
• Blind Flange: A solid plate used to close off the end of a pipe or vessel opening.
• Slip-On Flange (SORF): Slips over the pipe, welded inside and out for moderate service.
• Lap Joint Flange: Used with a stub end, allowing for easy alignment and rotation.
• Socket Weld Flange: Pipe inserts into a socket for a clean, strong weld, ideal for smaller pipes. 

Standards & Grades:

• Materials: ASTM A182 F304, F316, F304L, F316L, etc..
• Dimensions/Pressure: ANSI B16.5, ASME B16.47, Class 150 to 2500 ratings.
