SS Flanges, or Stainless Steel Flanges, are precision-engineered forged or cast rings designed to connect pipes, valves, pumps, and other equipment in piping systems. These flanges facilitate secure, reliable joints that allow for easy disassembly, cleaning, maintenance, or customization of pipelines. Manufactured from high-grade stainless steel, SS Flanges offer excellent corrosion resistance and high durability under extreme pressure and temperature conditions. Available in multiple types and sizes, these flanges support various connection methods, including welding, threading, and bolting, making them versatile for diverse industrial applications. Commonly used flange types include Weld Neck (WN), Slip-On (SO), Socket Weld (SW), Threaded (TH), Blind (BL), Lap Joint (LJ), and Orifice / Ring Type Joint (RTJ), each tailored to specific use cases from high-pressure petrochemical plants to low-pressure piping systems. Ideal for industries such as oil & gas, chemical processing, power generation, and shipbuilding, SS Flanges ensure robust, leak-proof pipe connections critical to system safety and performance.
